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)

Re: 7-men : all 43/43p EGTs created
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 . How much is it in your case? (maybe default is 60?) It is true that the side to move is different, but the colors of the piece...

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 ...
