Now I want to share with you the most interesting moments from my games in Dublin. I also asked other players to do the same here.
My report you can read in our forum:

In my site you can also find many photos:

14. 1-5?
Loses, escape is maybe possible after 14.1-6* - etc.

(Mac Banks sent me his remark:
Looks like the 1115 pitch right away will draw-Continue: 1115 1910 2-6 14-9 6-15 3026 7-11
9-5 3-8 2623 1116 2318 1519 1814 1923 2218 1619 3228 1317 1410 1722 1814 2225 2117 2530 10-6

10. 14-18 30-25 11. 10-14
Easier 11. 1-6 27-24 12. 7-11 – etc.
11…. 27-24 12. 1-6?
Now it loses, escape was possible after :12. 14-17 21x14 13. 7-11 16x7 14. 3x17 26-23 15. 17x26 31x22 16. 18x27 32x23 17. 2-6 – etc.

8…. 17-13?
Give the initiative to red. It needed: 8…. 25-22 9.18x25 29x22 10.6-9 17-13 11. 1-5 – etc.
9. 14-17* 23x14 10. 17-22 25x18 11. 15x22 27-23 12.10x17 21x14 13. 6-10 14-9 14. 10-14 32-27 15. 14-17 9-5 16. 22-26 31x22 17. 17x26 19-15 18. 11x18 23x14 19. 26-30 14-9 20.12-16 9-6 21. 1x10 5-1?
Mistake, White had to move first: 21…. 24-20 – etc.
22. 16-20 1-6?
Loses, White had to try: 22…. 24-19 – etc.
23. 2x9 13x6 24. 10-15 6-2 25. 7-11 2-6 26. 30-26?

In our second game Filip used his chance:

Red are better, white have to defend.
9…. 26-23 10. 16-19 23x16 11. 12x19 30-26 12. 3-8 27-23 13. 8-12 23x16 14. 12x19 31-27
14…. 32-27 – is stronger
15. 5-9 27-23 16. 19-24 28x19 17. 15x24 23-19?
I think that it is a solving error , maybe draw was possible after : 17…. 23-18 18. 10-14 18-15 19. 14-18 22-17 20. 18-22 26-23 – etc.

White surrendered after some moves - RW.

14. 11-15?
Solving error, red should choose 14. 3-7 19-15 - etc. with complications.
14…. 19x10 15. 6x15 25-21* 16. 17-22 23-18*
I did not notice such a nice manoeuvre

11. 1-5
Red set a trap: 11…. 21-17? 12. 15-19 23x16 13. 9-14 – RW
Better: 11. 7-10 12. 18-14 9x18 19. 23x7 3x10 20. 21-17 15-18 – etc.
11…. 23-19 12. 15x24 18-14 13. 9x18 22x8 14. 3x12 32-28 15. 7-10?
Loses, red had to play : 15. 7-11 28x19 16. 11-16 – etc.
15…. 28x19 16. 2-7 25-22 17. 7-11 22-18 18. 11-16 27-23* 19. 20-24 21-17 20. 13x22 26x17 21. 24-27 31x24 22. 16-20 18-15 23. 20x27 15x6 24. 27-31 6-2?
When all job was done, suddenly there came a vision from Russian draughts to me, I really thought that on 25. 31-27 - I could win: 25…. 17-14? 26. 27x9 2x13?? - Russian King can jump so… Easy wins 24….. 17-14 – etc.
28. 31-27
– now I remembered the English rules, but it was too late and I had to agree with Draw

Igor Martynov – Thomas Wien
QT 2010 (Rd.1, G2)

Image

10…. 27-24?
I was sure that red were good and started the calculations. To my dismay I could not find even a draw at first. For example: 12. 16-20 31-27 13. 11-16 18-15 14. 2-7? 22-18 15. 10-14 25-22 16. 7-10 29-25 – WW. Then I continued looking for the escape and found out the win(!): 14. 9-14* 22-18 15. 13-17* 18x9 16. 6x13 15x6 17. 2x9 21x14 18. 9x18 23x14 19. 16x30 – RW.
Red had to play here: 10…. 22-17 11. 13x22 26x17 12. 9-14 18x9 13. 5x14 25-22 14. 16-20 31-26 15. 11-15 19-16 – etc.
11. 16-20 31-27 12. 11-16 18-14 13.9x18 22x15 14. 13-17 – with an easy win – RW.

Now two games with comments of Shane McCosker (North Ireland) – the third best player of the World Qualifier 2010.

Black: Shane McCosker
White: Filip Kareta

11-15 22-18 15-22 25-18 9-13(A) 29-25 10-15(A) 18-11 8-15 24-19(B) 15-24 28-19 4-8 25-22 8-11 27-24 6-10 24-20 2-6 23-18 5-9 31-27(C) 10-15 19-10 6-15 32-28(D) 1-5(E) 27-24 7-10 24-19 15-24 28-19 9-14 18-9 5-14 21-17* 14-21 22-18! Draw

(A) A Secondary attack from the more usual 8-11 & 12-16 counterparts.
(B) 25-22 4-8 23-18 8-11 27-23 & 5-9 transposes into a CR Wagram.
(C) Now into one of Richard Pasks key landings the text move was taken in the Moiseyev V King 2003 WCM and may be slightly better than the more usual 26-23.
(D) 27-23 is the usual draw line here but my opponent finds another way to play this position.
(E) Red also has the unusual sacrifice in 12-16 cont: 27-24 7-10 26-23 10-14! 24-19 15-24 28-12 1-6 30-26 6-10 20-16 11-20 18-15 10-19 23-16 20-24 16-11 24-27 11-8 27-32 8-4 32-28 4-8 28-24 26-23 24-27 22-18 to a probable Draw

Black: Tom Watson
White: Shane McCosker

11-15 24-20 12-16 20-11 7-16 22-17 9-14(A) 25-22 16-20 23-19 15-24 28-19 8-11(B) 19-16 11-15 17-13 15-19 26-23 19-26 30-23 4-8 29-25 5-9 22-17 10-15(C) 17-10 15-19 16-11 8-15 23-16 15-19 10-7 2-11 16-7 3-10(D) 25-22 10-15(E) 21-17 19-24 27-23 24-27 31-24 20-27 23-18 27-31 18-11 31-26 11-8 26-30 8-3 30-25 3-8 25-18 17-14 18-15 14-5 6-10 32-28 10-14 28-24 14-17 24-20 17-22 20-16(F) 22-25(G) 8-3 15-10 13-9 10-14 3-7 White Win.

(A)8-11 is a great alternative here inviting the 17-14 dyke.
(B) 5-9 is given by Willie Ryan in his big league checkers to draw but recent improvements in published play would suggest that this move should be avoided for further play on this move see Wyllie Pro V A.Moiseyev or T.Canning V M.Banks.
(C) Red has a much simpler way here with 2-7 cont: 32-28 8-11 25-22 11-15 23-19 15-24 28-19 and the 10-15 exchange will draw
(D) After this series of exchanges white can force the win from here on.
(E) 9-14 22-18 14-23 27-18 1-5 21-17 5-9 & 31-27 WW
(F) This move allows a draw as red can advance his king to square 2 preventing white from ever crowning a third king.
(G) White can now force a win after this move

Now comments of Filip Kareta (Czech republic) who was the 4th in the Irish Open. As you can see, he also commented the games with me and Shane, just as we had done before. I found that it is very interesting to watch the games from both sides.

Kareta,F - Martynov,I
Irish Open 2010, 24.10.2010

1.11-15 23-18 2.09-14 18:11
In the first game, I jumped 18-9, so Igor wanted to play something different. I think he underestimated me a little bit. Diagram 1 after 18-11.

Image
Diagram 1

3.08:15 22-17 4.04-08 25-22 5.08-11 17-13
Igor wanted to encircle me, but I had a possibility of making a strong dyke on my left wing.
6.11-16 24-20
24-19 with the jump on 11 was probably better at this point. Diagram 2 after 24-20.

Image
Diagram 2

7.14-18
After the game, Igor said that he did not expect this move at all. I think it is stonger than 16-19.
20:11 8.18:25 29:22 9.07:16 26-23 10.16-19 23:16 11.12:19 30-26 12.03-08 27-23 13.08-12 23:16 14.12:19 31-27
Diagram 3. 31-27 probably looses, 32-27 draws.

And Igor did not expect this move too. 14-18, 32-28 draws.

I wanted to put pieces on 14,18,23, make an exchange and get into kingsrow.
24-20
This move made the position much more simple for me.
44.31-27 32:23 45.26:19
4 against 4. White resigns. 1-0

Kareta,F - Hannigan,M
Irish Open 2010, 24.10.2010

1.12-16 21-17 2.09-13 24-20 3.08-12 23-18 4.03-08
I like this formation, which is also used for example in Alma opening. Diagram 1.

This move was really good. :) See diagram 2.

30-25
[ 13...18-14 Should draw. 2-6 or 6-10 give some chances to black, but I think it does not win.

9-13 ? leaves the pressure and leads into draw.

My biggest weakness were the endings. I could win this game, but I did not see how to do it. Diagram 3 after 27-31.

McCosker,S - Kareta,F
Irish Open 2010, 25.10.2010

1.11-15 22-18

2.15:22 25:18 3.09-13 29-25 4.10-15 18:11 5.08:15

27-24 9.06-10 24-20 10.02-06 23-18
See diagram 2 after 23-18. Another possibilities were 19-16, but it is weak and 32-28, which leads into an even game.

19.14:21 22-18 Draws. ½-½

Kareta,F - Oliphant,D
Irish Open 2010, 26.10.2010

This game was played in the last round of Irish Open. I wanted to be in TOP 5, so I had to win.
1.10-14 23-19 2.14-18 22:15 3.11:18 25-22 4.18:25 29:22 5.08-11 27-23 6.06-10 22-18 7.04-08 26-22 8.02-06
Shane McCoscer played a similar formation against me (see the previous game) and I think it is quite sound here. 9-14 instead goes into a peaceful draw. Diagram 1.

Black controls the centre.

Now the games with comments of Michael Shabshai (Israel)– the third best player of the Irish Open 2010.

M. Borghetti – M. Shabshai

Image
White move
At first the position looks simple and does not represent any interest. Inthe calculations white were going to play 27-23, but refused because of the unwillingness to give a chance to the opponent of exchanging 3 to 3: 13-17 and 6-9 - etc. The game continued:
28-24 6-10 30-25?
And loses! It was necessary to play: 22-17 13-22 26-17 - etc.
10-17 25-21 2-6 21-14 6-9 22-18 13-17 26-22 17-26 31-22 8-11
In this position white realised that the situation was critical, and the only chance to continue the struggle – offering a man for the purpose of making a king.
24-19 7-10 14-7 3-10 32-28 4-8 27-24 10-14 24-20 22-18
does not escape, if 19-16, then 11-15 16-12 8-11 22-17 9-13 17-14 15-18 12-8 11-15 8-3 18-22 3-7 15-18, - etc.

Evident demonstration of deepest theoretical knowledge and the high realisation techniques from the new challenger of the World title, Michele Borghetti!

R. Tovagliaro – M. Shabshai

Red move

White has a winning position, but it is important to find the accurate plan in a short time. In the expectation of red - 25-29 white thought between two possibilities:
1st: 25-29 28-24 29-25 24-19 25-22 17-26 23-30 19-12 - etc.
2-nd: 25-29 28-24 29-25 17-22 23-26 22-15 26-30 15-18 – etc.
All of the sudden it followed:
18-22?
Red gives three (!) peaces at once!
27-18 - ???
Terribly, but from the unexpected last move white impulsively took a man 27. Touched and go! «Dura lex, sed lex» - «the law is severe, but it is the law» - as ancient Romans spoke, ancestors of Roberto Tovagliaro. It was necessary to go. Furthermore:
25-30 17-26 30-14,
And later red realised the advantage and won. So my crystal dreams of the big victories and medals in the tournament were broken.

Bashim Durdyev – M. Shabshai

10-14 24-20 14-18 22-15 11-18 23-14 9-18 21-17 8-11 28-24 11-15 17-14 4-8 26-23 8-11?
It loses, look the next diagram

Image

Red falls into the placed web of traps. Instead of 8-11 it was necessary to play 6-10 25-21 10-17 21-14 1-6 – etc.
30-26!
Red noticed too late that on 6-10 follows 23-19! 10-17 19-10 7-14 26-22 17-26 31-8 – with big chance for a win.
6-9 26-22 11-16 20-11 7-16 23-19! 16-23 25-21 18-25 27-11 9-18 29-15 12-16 31-26 16-20 26-22 20-27 32-23,
And further white realised the material overweight.

I invite all other players to join this topic. It will be our general contribution to development of Checkers.

Dear Igor,

before I start with analytical comments, there is a mistake I spotted:

Surely the game Martynov-McElhone ended in a White win, not a Red win.
Typo ;-)

And Martynov - Kareta games are probably from the IO, not the QT.
Typo ;-)

---------------------------------------------------------------------------------------------
Analytical remarks:

1. Webster- Martynov, IO 2010 (Rd.9, G2):

A)I think the position is already quite bad for red.
I think that 14. 1-6 might lose as well, and think that 14.11-15 19x10, 15.2-6 migth be better, but still worse for red.

B)Note that 14.1-5 is not a mistake, as after 14. ... 22-18 red may play 15. 13-17! with the idea of 15. ... 30-26??, 16. 11-15! and red might even win!!
But not so fast, as 15. ... 31-27!, 16.17-22 21-17, 17. 11-15! might give red a narrow escape, but at least the chance to ask for a long, technical difficut , but more likely still lost endgame.

2. C.Young - Martynov, QT (Rd.7, G2):
Note that your 12. ... 16-11 corrects an old Bryden-Searight game from the Scottish Ty. 1894, which ended drawn after 12. ... 31-27, 13. 7-11 etc.

3. Martynov-Kareta QT (Rd. 3, G1)

you wrote that 22. ... 1-6? loses, but your 22. ... 24-19 is not the right way, as 23.30-26! 1-5, 24. 26-22 5-9, 25. 22-18 9-5, 26. 10-15! still wins.

Best idea in my opinion is 22. ... 1-5!, but after 23.30-26 29-25 (denying the square 22) red is still very strong, might be even winning, but technical difficulties are still to solve.

4. Martynov-Wien, QT (Rd. 1, G2):

Note that this is a known theoretical position from Kear's encyclopedia, p. 422, v.12
The correct 10. ... 22-17 to draw is given there.
Monteiro - Rolander, US nationals 1980 is a further reference for that line.
Note that 10. ... 19-15? has been tried in Binsack - McRae, 1929 US nationals, Cedar Point, but lead to a dead loss.

5. Kareta - Martynov, Irish Open 2010, 24.10.2010:

5. ... 17-13 is indeed bad, and theory gives 5 ... 26-23 and 5. ... 24-20 to draw, but red is better in this line anyway.
Note , as Grover pointed out ("Let's Play Checkers"), the take 2. ... 18x11 must be followed up by 22-18 to secure an equal game.
I remember that the late Richard Fortman played the 3. ... 22-17 online on IYT against me for fun, and lost as well.
He later remarked to me that it might be close to a loss after the game, and certainly 3. ... 22-18 is stronger.

6. Kareta - Hannigan, Irish Open 2010, 24.10.2010:

Filip is right that 13. ... 18-14 draws.
It was played in a Hallett - Oldbury game in 1985 to a draw.
13. ... 30-25 is inferior and loses indeed.
But it's not 33. 27-31 giving away the win, but maybe 37. 17-22 20-16, 38. 22-26 15-18, 39. 28-32 18-15, 40.26-23 24-20, 41. 32-27 15-10, 42. 24-24 10-15, 43. 4-8 wins, even after the unnecessary exchange of the man on 29.

There is a rule in endgames for chess Filip:
take your time to exchange, make a few manouvers before, just to see if he makes a mistake, and to clariy who is the dominating force, and let the fish on the hook as long as possible, so the man on 29 did not have to be released from his prison that early ;-)

7. Kareta - Oliphant, Irish Open 2010, 26.10.2010:

Actually 7.4-8 seems to be new, 7. 9-14 has been played before, and after that your remarks are quite true.
8. ... 24-20 is indeed better.

8. M.Borghetti - M.Shabshai

The move 9. ... 30-25?
was also played before by Battersby against Henderson, Scottish Ty 1901, and Henderson went on to win,
see Dunne's "Modern Match Games".
It pays off to know the classics, and Michele knew.

Re: Dublin 2010

Postby Ingo_Zachos on Fri Nov 26, 2010 8:58 am

Dear John,

thx for your very god idea to publish the game animated.
Also thx for your fine blog.
It is appreciated by many checker friends.
----------------------------------------------------------------------------------
As for the game:

Kee, T. - McElhone, J., Irish Open 2010 (Rd. 1, G2):

A) Opening theory:
5. ... 18-15 is new, as 5. ... 17-13 had been played before.
18-15 is indeed a advance that is also essential in the 3. ... 27-24 line you mentioned.

After 6.7-10 you could have got back to games like MacCarrick, C. - Devlin, H., British Open 1986 ( a later white win) and McCarty, J. - Glennie, D., Home Internationals 1988 (a later red win)

your 6. ... 22-18 might be new play, and now there are many complicated lines like 7. 19-23 , but not 7. 9-14 , as in the game, after 8. ... 17-13 I also think white is strong, perhaps already winning.

As your suggestion 10.14-18 runs into the powerful 10. ... 13-9!, 11.6x13 15x6, 12.1x10 27-23!, 13.18x27 31x6, 14. 2x9, and as white is dominating in the centre and can advance to the kingsrow due to his minority on his "left wing", while red is blockaded on his majority wing (left wing) by the dominating white centre. I suggest it is a white win.

So if there is no improvement (note that 9.14-18 also runs into the 9. ... 13-9! idea.), I assume that 7.9-14 is the losing move, and 7.19-23 might be better.
------------------------------------------------------------------------------------------------------------

B) Midgame:

10. ... 28-24! is indeed a very fine and strong idea.
Good positional judgement on your side to see that you would win on your left wing!
And this is how calculation and positional judgement should work:

Calculate to a promising postion, and then either find the shot or the winning "plan", as the concrete moves can be traced later, once you reach that position.
Many games have been lost by trying to "push further" with calculations, but note that deep time trouble is the dead of the perfectionist.
Only make sure that your judgement is correct!
--------------------------------------------------------------------------------------------------------------------

C) Endgame:
Well, until the end when 3 vs. 2 is reached, there has been no endgame, but rather a transitorial phase that seems impressively easy, as you had the right plan.
---------------------------------------------------------------------------------------------------------------------


Summary:
A very fine game, with a fine positional sacrifice being the icing on the cake.

Great idea for a thread and i have loved reading the analysis and comments provided.
How do you insert the animated game? i loved it and i thought it was very instructional, whats the name of the program etc.
