V. Shafir vs J. Tikhy, G1

Summary of errors in this game: White missed one strong continuation and one win, Red made one losing move.

See position on diagram #1. Kind of "phantom treats and phantom scares". Red just played 11-16 trying to trap white pieces and force them to run out of moves. it would be true to say that sometimes it works, but not in this specific case. However only deep, complicated calculations can prove one or another thing. So, potentiality to run out of moves was a "phantom scary" for white and they played here 24-20 which cleans the board, keep small advantage and ... missed a big winning chances !

22-18 in position on diagram #1 would force red to make several star moves in the row to survive. For instance, natuarl 5-9 after 22-18 loses by powerful 18-15 and now red runs out of moves after 16-20, 32-28, 17-21 (or 1-5, 23-18, 7-10, 18-14*, 9*18, 15-11*, 8*15, 26-22 WW), 26-22, 1-5, 23-18 etc WW

Here is a trunk drawn line on diagram #1 after 22-18 :

6-10, 18-15, 8-11, 15x6, 1x10, 24-20, 10-14, 27-24, 7-10, 13-9, 17-22, 26x17, 14x21, 31-26, 5x14, 26-22, 14-17, 22x13, 2-6, 32-27, 4-8, 30-26, 21-25, 26-22, 25-30, 22-18, 30-26, 18-15, 11x18, 20x4, 10-14 Draw

In position on diagram #2 red played losing 10-15? instead correct 11-15 and after then white played it perfectly until end of game where mistakenly agreed with draw in winning position !

Position on diagram #3 was a final position in this game where draw was agreed and ... white had a clear and the only win by 20-16* !

M. Bernini vs M. Borghetti, G1

In position on diagram #1 Matteo played suspicious 11-16? allowing white powerful 22-17 and danger ending. Michele immediately used all his chances. Instead 11-16, the program suggested waiting 4-8, however I personally would play more boring 9-13, 2-6, 6-9, 9-14 etc with Draw

After 11-16, 22-17, 9-13, 17-14, 10x17, 21x14, 13-17, 14-9, 5x14, 18x9 red had a first chance to play 16-20, 4-8, 7-10 to stop white King from coming back to center. Matteo played 17-22, 9-5 and they reached position on diagram #2. Here red had last chance to play 16-20 which leaded to some sort of very weak computer draw, but he played 22-25 (hence, I would probably do the same 9 times out of 10!) and eventually lost. Michele crowned his 1st King and came back to arena. Since then red didn't have a time to play 16-20 and eventually Michelly attacked it first 24-20 and crashed red position.

So far this game seems to me as best Miki game in this event where he played it perfectly at all stages - opening, midgame, ending phase - and won nicely an important game against strong opponent.

Bashim Durdyev vs R. Beckwith, G1

See position on diagram #1. Somehow important position which has a high theoretical value. Bashim played here over-aggressive but not accurate and critical 16-19?. Instead, 9-13 should give him an easy game after 17-14 (anything better?), 16-19, 23x16, 12x19 and noone has advantage here.

After 16-19 on diagram #1 game continued: 23x16, 12x19, 27-23, 4-8, 23x16, 8-12, 32-27, 12x19, 27-23, 19-24, 28x10, 7x21 and we reached position on diagram #2. Here Richard missed an important crucial tempo by playing 22-17 and allowing red to consolidate their forces 1-6*, 23-19, 6-10 etc Draw.

Instead 22-17, white should play aggresive 23-19 trying to break red position via center. Program shows a clear win now (after 23-19) which makes perfect sense. Red can't avoid white danger attack and everything goes up for white increasing their advantage and power. For instance ... 23-19, 9-14, 18x9, 5-14, 1-6 19-16* etc WW

D. Oliphant vs P. Faleo, G1

In this very interesting and instructive game red lost on time where they actually already had losing position. Most interesting things happened in midgame and ending phase of game. I am giving here just collection of missings.

On diagram #1 red already has very danger position but draw was still available by 4-8. Instead, red played 1-6? and after 27-23*, 19-24, 28x19, 15x24, 23-19, 24-28, 19-16, 28-32 the reached position on diagram #2.

Here white missed a win by 31-27? trade. Win was stil,l their after 16-11* and white crown King on time and "handle" red ducks on the right flank.

Continue from diagram #2: 31-27, 32x23, 26x19, 4-8, 16-12, 8-11, 12-8, 11-15, 19-16 ... See diagram #3. Another midgame masterpiece, 15-18 still alows draw, but 10-14? as played in the game loses.

U. Hydyrov vs S. Thrane, G1

Before position on diagram #1 gets on board, red played couple moves ago 16-20 which appears to be out of order. Position on diagram #1 appears as an earlier loss for red after 17-14*, 10x17, 21x14, 1-6, 19-15, 12-16, 29-25* etc Probably WW Actually there is much more play involve here and I am leaving it (and final verdict) for analysts

Instead 17-14 white played 27-23 allowing red 11-15 with even game. Instead, red played 9-14?, 18x9, 5x14 which appears now as another loss after 30-25*, 1-6, 22-18, 13x22, 18x9, 6x13, 26x17, 13x22, 25x18 ... see diagram #2. I was unable to find scientific draw for white. White just wants to play 18-14 and completely destroy red position. 11-15, 18x11, 7x16 can be well meet y 31-27* WW

Nothing this happened in actual game and after several moves they reached position on diagram #3. White played here 23-18?? and immediately lost after 3-7*, 31-27, 20-24*, 27-20, 11-16, 20x11, 7x23 and white man on 18 jeopardise.

R. King vs Bagtiyar Durdyev, G1

See position on diagram #1. Another earlier loss and nice addition to pulished play. White just played 17-13?? (17-14 is correct) and this looks like complete loss for white at the earliest stage of game !

In position on diagram #2 Ron played "provoke" move 8-11 and missed a win. After simple 9-14 white should run after move. The game continued from position on diagram #2: 22-18, 15x29, 20x4, 12-16, 20x11, 7x16, 8-4, 29-25 and they reached position on diagram #3.

27-24 should save the game by running this man to 12 and free King on 4. Instead, white played 28-24 and lost immediately after 16-19, 24x15, 10x19, 26-22, 25x18, 27-23, 19x26, 31x15, 9-14, 30-26, 14-17 RW

J. Jolliff vs I. martynov, G1

See position on diagram #1. Red played here losing 8-11? (7-10 correct) trying to prepare later 20-24 but in this particular situation it didn't work and seems to be a loss.

Due to health conditions (no other reasons!) Igor performance in Lille was well below his real level and strength (having a little luck and good physical form he can fight for medal). Even though he won this game, but it was more like his opponent fault, not Igor accomplishment.

Later they reached position on diagram #2. Here 32-27 should immediately finish the game where red just run out of moves. Instead, Igor played 29-25? which missed a win. Red can drew the game by 17-22, 25-216-9* etc Draw Instead 17-22 after 29-25, red played 20-24?, 25-21, 17-22 and now again Igor missed a win 32-27, 16-20, 30-26* etc WW.

Continue from diagram #2 ... 29-25, 20-24, 25-21, 17-22, 18-14, 10x17, 21x14, 16-20, 14-9 ...

See position on diagram #3. John lost it by 22-26??, 31x22, 24-27 etc WW. But simple 24-27 would drew the game without much troubles.

C. Freeman vs G. Owens

See position on diagram #1. Charles played here 10-14 and ... missed win - truly brilliant problem !!! When I first time looked at this position I didn't beleive my eyes ... Yes, red has a wonderful "problem-like" win here: 27-23, 7-2, 23-19, 16-11, 10-14, 11-8, 15-18**, 22-15, 19x10 - see diagram #2.. Here red have one King against two and "still can manage a capture of white man on 25 and win game. WOW

Red to move

O. Kolin vs S. Scarpetta, G1

8-11? and game is over - lack of PP knoweldges. This position is well known to PP where 6-10* is the only drawn move.

2nd game of 7th round will be processed later in different post.

Yes i was crowing in an earlier post that Bashim had found a NEW line in the SKUNK alas 23-19* blows it out of the water.

Richad played the 21-17 line which isnt g great against 9-13 with 27-24 the POWER going back into PP.I guess he didnt read Cannings Comp yet??

S. Scarpetta vs O. Kolin, G2

No errors and no blood in this game. However I decided to select it because it's close to perfect in my eyes ! Both partners played it right, with probably best moves though it wasn't a classic published play but original game. I diagrammed it where white went out of main line. I can't recommend this for variety because I think only red really may have some chances here, however it is very nice addition to checkers history ... at least I am unaware of play (game database may still have something).

Bagtiyar Durdyev vs R. King, G2

The game was opened by 10-15, 24-20, 6-10, 28-24, 23-19, 12-16!? ... see diagram #1 before 12-16. One time I also played this with Michael Holmes , got into very wreckless position but was lucky to escape. I saw this extremely suspicious move several times. often people make it in order to escape published play. However, red position is so bad after this trade that I even call status of this move UNTESTED and question it's soundness !

See position on diagram #2. Kingsrow opening book give here 25-22 as best with high advantage and I agree with this. Due to some circumstancies the main strategic idea in this position - red pieces are overdeveloped and trapped and often run out of moves.

After trade Ron played 21-17 which makes sense. He tries to take another corner and if red allows to do this - their position must be complete mess and loss. The golden rule says: "whoever controls both flanks - controls everything !" This game demonstrates prefectly how this rule works. In order to avoid white to play 17-13, red has only one move which may save game: 9-13!. After this red should OK. I am leaving it to analysts.

Finally, after several moves they reached position on diagram #3 where Ron won pretty with pitch: 12-8, 3x12, 21-17 WW. To disappointment of Bill Salot, I should say that position on diagram #3 cannot be call as problem, because white also had another (alternative) win here 23-18.

Diagram #1. Red to move ......... Diagram #2. Red to move ......... Red to move

F. Kareta vs J. Morrison, G2

To Bill Salot excitement: Attention - this is a problem !!!

Perfect example of problem happened in practical game. Red has the only draw in position on diagram #1 and if they play a wrong move white has the only wins. This wonderful midgame position combine several tactical and strategical ideas and is a perfect example to demonstrate complexity an beauty of our game.

From position diagram 31 game continued 24-20 (A), 23-18, 15-19, 31-27 (B), 3-8, 18-14, 10-15. 17-13, 8-12 (C), 13-9 etc WW

A. Missing a draw. Suspicious 15-19 was correct: 23-18, 3-8 (to avoid 18-14), 31-27, 16-20 (the only drawn move), 18-14, 10-15 converting into play happened in game. See comments to note C.

B. See position on diagram #2. 31-27 here misses a win for white ! 18-14 was correct in order to keep man on 31 and avoid draw in note C.

C. See position on diagram #3. And ... yes!, red had here a draw by 1-6*, 278-23, 8-12, 23x16, 12x19, 14-10, 5-9, 10x1, 9-14 catching white man.

Nice.

R. Beckwith bs Bashim Durdyev, G2

Richard played here 3-7 ?? and immediately lost after 22-17. Instead, 9-14 here is correct. In order to save electronic space and some money for ACF, I address you for details to Canning Compilations, 2nd edition, Pg.5 where this position is diagrammed (after 9-14) and analysed

Diagram #1. Red to move ........ Diagram #2. Red to move ......... Diagram #3. White to move
Image . Image . Image
P. Faleo vs D. Oliphant, G2

See diagram #1. Paolo find here a nice and the only way for red to stay out of troubles: 10-15!

See diagram #2. Here red played losing 16-20? Both 7-10 and 1-6 are OK. After red played out of center 16-20, white has a win by going through center and destroying red position. Continue from diagram #2: 16-20, 25-22, 8-11, 27-24 ?? ... Another surprising move which miss a win. What really scared white ? I'll take a chance and say that they didn't see the following play: 29-25, 11-6, 18-15, 14-18, 23x14, 9x18, 31-26*, 16x23, 26x19 and white wins a man at next move.

After several moves players reached position on diagram #3 and here white made a final mistake by playing losing 29-25?. Instead, 30-26 should still draw it. After 29-25, 3-7, 32-28, 13-17* Red Wins

!!! ACCORDING RECORDED TEXT, GAME #2 BETWEEN J. MORRISON AND F. KARETA IN 7TH ROUND JUST REPEATED 100% THEIR 1ST GAME !!!

S. Thrane vs U. Hydyrov, G2

In position on diagram #1 at the beginning of game white played here 22-18 going to the even game. However they had much better option: 19-15*, 10x19, 17x10, 7x14, 27-24 and red defence here is very delicate.

At the end of game players reached position on diagram #2. Usually I place diagrams at the moment where mistake made. However in this particular case I decide to place diagram several moves in advance to critical moment. Game continued from diagram #2:

12-16, 18-15, 9-14, 15-10, 14-18, 10-6 and ... yes!, 18-23 ?? and red lost.

I. Martynov vs J. Jolliff, G2

Position on diagram is drawn and actually noone missed anything and draw happened in game. However ... checkers is not game of win-draw-loss, it's game of chances ! Igor played here 21-17 etc to Draw. However, in terms of chances I would definetely try more poisen 22-17* forcing red to make several star moves: 8-12, 26-23, 12-16, 30-25, 16-19, 23-18, 14x23, 27-18 White better

Charles lost this game on time. In position on diagram, after 1-5? (1-6 correct) he missed "one second chance" to score a fine win after 32-27*.

Re Scarpetta v Kolin G2 - 10-14, 24-19, 11-16,

The game may have been "close to perfect", but at the 9th move 23-19 (instead of 22-18) leads to a much more critical and difficult game for Black and a difficult ending as per Oldbury v Tinsley Game 30.
This is supported by Fortman in Basic Checkers who commented:
"The 22-18 exchange is premature..... Red draws easily ...."

Yes, mea culpa.

Thx for pointing it out. I will look for the score sheets and try to mend that mistake in a future edition of the games.

If you found or suspect any further error, plz indicate it at once. A plan to revise the games based on the score sheets anyway at leas in that games in which the pnd ends with a remark that the rest was unreadable.
Sometimes it is unreadable, but with some time-consuming detective work the games sometimes can be reconstructed.
