Hi everyone
Many thanks for help ,I think that I am getting it now.
Here is my second game against King
12-16 ; 21-17 ; 9-13 ; 22-18 (A typical King move and threw me off book immediately) 13x22 ; 26x17 ; 16-19 ; 23x16 ; 11x20 ; 17-13 ; 8-11 ; 25-22 ; 4-8 ; 24-19 ; 10-14 ( With this and next moves my intentions are to try and overcrowd white in center and render useless to white the black man on 20) 18x9 ; 5x14 ; 29-25 14-17 !! Forms diagram :

Black Docherty White King

White to play

Image

As expected King plays 3126 ; 6-10 ; 22-18 ; 17-21 ; 13-9 (of course not 25-22) 10-14 !! ; 28-24 ?? ( 27-23 lets Black in for king ;; and if 25-22 I had up my sleave 14x23 ; 27x18 ; 812 and now 19-15 cannot be played for 21-25 shot ,, so white must give space to black ;;; and lastly 26-23 ; 14-17 loses a man eventually ) 14x23 ; 27x18 ; 20x27 ; 32x23 ; 8-12 ; 23-19 ; 16x23 ; 26x19 ; 3-8! ; 25-22 ; 1-5 ; 9- 6 ;2x9 ; 22-17 ; 7-11 Etc. Black won

Instead of 13-9 ; I would tend towards a move like 26-23 to obtain the draw for Ron

William, in your game with Mustafa 22-17 on his part was very weak, critical move (though draw still exists) and 17-14 was a losing move.

7-10? loses, 3-7 draw

In position on diagram Shane played losing 7-10? and game continued: 14x7, 3x10, 25-22, 10-14, 32-28, 5-9, 28-24, 11-16, 24-20, 16x23, 26x19, 14-17, 22-18, 18-22, 19-15, 13-17, 15-10, 17-21, 10-6, 22-25, 6-1, 25-29, 1-6, 9-13, 6-10, 29-25, 10-14 White Wins

An interesting and amazing fact is, that red still had a draw in position on diagram! Continue ... 3-7, 32-27, 13-17*, 27-23, 6-10*, 23-18, 17-21, 25-22, 10x17, 22x13, 7-10, 26-22, 10-14 etc Draw

yes Alex

This is one of variations that we analysed to draw , back in hotel , after your game with Shane.

Despite His result in Beijing , he is still among the most promising " younger" players , and will definately show more
positive results in near future tys , and world titles..

R. King vs M. Shabshai
Rd.9, G2

White to move
Image
11-15? draw, 22-18 WW

This is position from last round and last game which Ron King played against Michael Shabshai from Israel. Having time troubles and less experience and knoweldges in ending field, Michael played here 11-15? and allowed Ron King to survive after 12-16, took 2nd place and earn Challenger rights.

22-18 instead won the game.

Michael started analyze his games on Russian checkers site which is certainly a great news !

Alex

While on the subject of " oversights " , I will be posting a few of my own.

In fact in this ty. My mid-game play was meticulous , but on more than one occasion all that hard work was thrown away by

that " Unexplainable impulse " to move something else !!!!

This happened in , amongst others , one of the games I had against Allicock

R.1 G.2
Black -Docherty White - Allicock

Black to play and win

Image

I played 24-20 ?? , allowing 11-7 ; 3x10 ; 12- 8 ; then press the man on 10.

In fact 24-19 Obviously more natural wins , because if 11-7 ; 3x10 ; 12-8 Back posts his king on 15 (after moving single to 18) and paries thus the press 3- 7 by simply moving 18-23 ,, resulting exchange is still man up.

I did not drink during the ty. but I will call these moves " Heiniken beer moves"

Here is probably the most important oversight for me of tournement.
3 points in this round would have given me Silver , and the win is on the Board.
Once again , I wasted my mid game efforts , on one move innaccuracy!!
I didn't have beer as an excuse so I will put it down to lack of ty.play

R.9 G.1

Black - Docherty White - Moiseyev
Image

Alex has just slipped 27-23 ; 20x27 ; and plays 23-18 ; to which I reply ; 6-9?? and realising immediately my error offer draw which is keenly accepted by my worthy adversary!

Black should play quite simply ; 27-31 after 23-18 then 18-14 ; 31-26 ; 14x7 ; 26-30 and 7-2 will be met by 30-25 Black will win.
This is how i saw silver disapear!!

For a player ,it is difficult to swallow , and even admit that such things can occur at such crucial points in game , especially
when in mid-games or x-board opening positions , complexe timings or combinations in various variants are being seen at a glance and at deep levels.
One explanation that I care foster is that during a game , there are signs, like traffic lights, where a player must stop and say ""hold"" let's look again ,and if this is not done then we pass by the draw or win .

I will now have to work in this direction , paying more study time to phase changes in game , and also on late midgame early endgame themes.
This is the lesson I brought back from China :oops:

Dear William ! Don't hurt yourself - it is only game, no more, no less :lol: Sometimes is very painful, but you have to handle this properly.

Finally I putted this position into Kingsrow, 10 pieces ending database and find something interesting. After red moves 26-30, the program choose 17-14 !? instead 7-2. See diagram below. After then it took for program almost 1 hour on my computer going into 33 plies search to confirm a win. The game certainly would not end at this point and went into very complicated man down play with some drawn elements (mans on 4 and 5). This would be another test for your luck. :lol:

Noone is perfect and certainly I am last in this line :D Checkers are sport - that what we well proved in Beijing. I also said before that it is not a problem to beat me in match or game - just don't make mistakes ! All my responsibilities as World Champion are simple and obvious - make sure that I play my best. And anyone who plays checkers better than me will be a next World Champion - this is the way it goes in history for more than 70 years: from one champion to another.

Hope see you back with full arms in next title cycle 2009-2010 and play our MAIN match.

I'll give you two interesting quotes here:

1. In 2002 when I made a phone call from DisneyWorld to Las Vegas and congratulated Larry Keen with his fine victory in USA National, he said: "I made less mistakes than others!"

2. Great Marion Tinsley said once, that he wanted to play some day a perfect macth, but yet never did.

Hi Folks;

In my second game against Igor martynov , a very strong x -board Russian player , the following position arose ;

Black- martynov White - Docherty

White to play

Image

At this stage during the game In calculations I ran through a couple of variations leading to following positions ;

# 1. Black to play

Image

Arising from 32-27 ; 6-9 ; 21-17 ; 9-14 ; x ; x ; 15-10 ! ; 2-6 ; x ; 19-24 ; 28x19 ; 8-11 ; 15x8 ; 6x24 ; 25-22 ; 4x11 ; 29-25 ; (Going to threaten 2 for 1) ; 1-6 ; 25-21 ; 6-10 ; 27-23 , And I did not feel the need to deepen study into position as a breakthrough for white is coming with strong endgame possibilities...


# 2. Black to play

Image

I felt this had to be checked quickly " just in case"

Arising from 32-27 ; 7-11 ; 21-17 ; 18-23 ; 27x18 ; 11-16 ; 20x11 ; 19-24 ; 28x19 ; 6-10 ; 15x6 ; 8x24 ; 18-14 and White will still remain a man up , and no entry for king for Black...



# 3. Black to play

Image

Arising from 32-27 ; 7-11 ; 21-17 ; 2-7 ; 17-14 ; 6-9 ; 27-24 !! ; (Igor told me after game that in this variant he had only calculated 26-23 in reply to 6-9! ) 18-23 ( another sacrifice line spotted during game was 19-23 ; 26x19 ; 18-23 ; 22-18 ; 23-27 ; 19-16 ; 27-32 ; 24-19 and did not worry me at all) ; 15-10 (I did not see during game but 22-18 is another possibility! And probably a lot Stronger despite the shot threats to gain king!) 9x18 ; 24x15 ; 7x14 ; 26x19 and with black to play I felt that white had slight advantage in very interesting position.


The game Actually went like this ;

32-27 ; 7-11 ; 21-17 ; 2-7 ; 17-14 ; 6-10 ; 15x6 ; 1x17 ; 22x15 ; 11x18 ; 25-22 ; 18x25 ; 30x14 ; 8-11 ; 29-25 ; 4-8 ; 25-22 ; 11-15 ; 27-14 ; 8-11 ; 31-27 ; 3-8 ; and 14-10 Well drawn by Igor , I think that we will be hearing more from him in future!!!!

Hi William, very interesting games and analysis.

Incidentally, in a "what if" mode, if the Beijing Tournament had been decided on rounds won and drawn (instead of the discredited 2 points per game system, inappropriate for 3move ballots) you would have been placed 2nd.
