EGC 3rd Round - More Exciting Happenings


In an electrifying match, Kim Youngsam ('Korondo' 9d on KGS) scored a win over Jeon Sang Youn 7d (they are both from Seoul, Korea). It was a very complicated game from beginning to end, where Kim showed great fighting skill. You can see their game here: please pay attention to B105 and the continuation; the result was impressive - Black killed the White dragons in the center! Kim's power must make his opponents tremble!

Catalin Taranu defeated Csaba Mero on board 1 by 15,5 points, and the young talent Thomas Debarre also pulled off another win (he beat Cornel Burzo today). But then, the game between Ondrej Silt and Alexander Dinerchtein stirred controversy...

Even though White (Alexander) made the game closer in yose, Ondrej was still a few points ahead. They were playing the final ko (nothing fancy, Black was leading regardless of its result) when Ondrej made a mistake (probably because of the pressure?): he recaptured the ko without making a threat!

Black had made an illegal move. We can't blame him, such mistakes can happen. Now the outcome of the game will ultimately have to be decided by the rules (Simplified Ing Rules).

If a player makes an illegal move, and if this is noticed within three moves, then the game should be unwound to the move just before the illegal move, and continued. The referee may allow an adjustment of the time.

     The referees decided that the players should continue the game, so Alexander resigned and wrote a letter to the appeal committee (which will meet tomorrow).

Ondrej Silt played a good game, so playing an illegal move was unfortunate... We can say that, if the appeal committee decides that he should lose the game, it may be "unfair", but it is important to keep in mind that that would not be the fault of the players, but rather of the rules.

If you play in the tournament, you play according to that tournament's rules. Unfortuantely those rules were not in your favor in this instance. It would be like arguing about an opponent playing suicide when you play in a tournament in New Zealand. It may be illegal in Korea, Japan, or China, but in New Zealand, that's the law of the land.

Penalized mistakes: Making two consecutive moves is against the rule of black and
white making alternate moves; recapturing a ko stone without an intervening play
violates the ko rule. In either case, the game is forfeited.

If the EGF document linked by Daniel Tom was indeed the rules in effect for this tournament, it seems clear that the referees made the correct decision. The games that Dinerchtein lists as examples are irrelevant, because they were played under the prevailing rules of that particular country or tournament and should not be considered as a precedent for judging a match played under different rules. This is even more apparent considering that the relevant EGF rule set explicitly handles the issue of playing an illegal move.

It would be surprising if the appeal committee decides to change their initial ruling in favor of Dinerchtein, since the situation was handled appropriately according to the rules in place at the time. Maybe the governing body will decide to change the rules for future competitions, but that shouldn't affect the result of this match.

Still a long way to go, and we look forward to more great games from you!

direct link to Cho Chikun vs Otake game from the Meijin title match:
http://senseis.xmp.net/?OtakeHideoChoChikun5thMeijinFinal1980IllegalCapture

"In this game, Cho Chikun recaptured the ko immediately, which is an illegal move that usually would result in a forfeit. However, because he had asked the scorekeeper whether it was his turn to take the ko and was told it was, the result was recorded as void instead of forfeit. Ko recapture forfeits are rare, but there are several examples in the history of professional Go."

And one more episode:
http://senseis.xmp.net/?Suicide

A very unusual incident occurred in the first round of the 15th Korean Kiseong tournament (2003-10-02). Cho Hunhyun 9p was forced to lose a game (against Choi Cheolhan) because of an illegal move. You can see the game record at the time of the infraction at go4go. Cho obviously intended to take the ko at a in the lower left corner when he made an illegal one stone suicide play instead

Few stories with similar cases:
http://senseis.xmp.net/?IllegalMove

Something similar happened a few years ago in the Meijin tournament in Japan, where Cho Chikun took a ko without making a threat. But on that occasion the game was annulled rather than forfeited, since Cho had asked the referee if it was his turn to take the ko and the referee had answered wrongly.

I was 3.5 points behind. I am not sure which kind of rules do we have on EGC-2011. At least, I never played under these rules myself.
In Korea and Japan the situation with illegal moves is clear.

"Moves that violate these rules cannot be made. The game is not lost by forfeit through such moves."
