Re: (for Guy Haworth?) Shortest legal mate
Well it seems 49. Kd5 is the only typo, should be corrected to 49. Nd5ernest wrote:it seems there are some typos.
For instance 48. Kc3 is followed by 49. Kc5
The DTM50 of my friend then agrees with your pgn (mate in 59)

Maybe clear your browser cache or try with a different browser? I think it simply has to do with the Posts Per Page option of the Rybka Forum. In my case, I have it at 70 .

Re: 3x3 chess
What kind of questions do you hope to see answered in 5x5 chess? Nothing in particular, Kirill, except that I enjoyed playing that game (through zillions-of-games) and that is the smallest chess with all pieces. And I am mainly interested in the variant with pawns on the 2nd and 4th rank, and symme...

Re: Mate in 15, How Long Does It Take To Solve?
The purpose of the test was to try and see if the time of 7:16 was "extraordinary" or not. OK Ed, I did the 3 consecutive tests, on the same Houdini 1.01 engine , but 32-bit and on my (lowly) Core 2 Duo @3GHz (2threads), 512 MB hash. 1st try: mate in 15 obtained in 26 minutes, at depth 31...

Re: Mate in 15, How Long Does It Take To Solve?
So there was some variance depending on the "state of the computer" at the time of the test. Hi Ed, I don't understand :o If those tests were done with MP, why do you relate the "variance" to the "state of the computer"? Isn't that the same as saying that the variance ...
