Re: Who is who?

Hi all, thanks for your analysis. Finally we are coming down to the truth of this position. And yes, Kc6 is really not so far fetched as idea. My arrogance blinded me :evil: . Normally i do check with stockfish, but this time i simply skipped that, because i was so proud applying the fortress idea, ...

Re: Who is who ?

For those who believe in engine playing styles I want to challenge them to tell "who is who" in this recent LTC game between Komodo and Houdini And of course with arguments about style of play [pgn] [Event "T"] [Site "C"] [Date "2014.06.07"] [White "X"] [Black "Y"] [Result "0-1"] [ECO "D30"] [TimeC...

Re: What would you do differently

I have downloaded your test code and tried it and can confirm your results. Actually you had been modest, with other parameters i got a speed ratio as high as 5 to 1 (!). It is true that the stl library code gives strong exception safety, but that alone can not explain that whopping difference. Besi...

Re: Test Position: Gudmundsson - Fischer, Reykjavik (1960)

Hi Marc, i have looked at the game you had shown. Nice attacking game of Fisher, but unfortunately i don't think that has something to do with material imbalance. Consider: [d]4r1k1/pp3p1p/2p3p1/5P2/5P2/2PB2KP/P1Q3P1/R1B1r1q1 w - - 7 24 This is a critical position after the sacrifice. Lets look at i...

Re: Solving the KID

I told you, because of the King in th king side and the Bishop in h6. Totally dependent on pieces. Miguel Where should be the king but in the king side in the KID? Castling short is 95%.

Re: Solving the KID

Secondly, SF has no eval term for chain pawns It does. Have a look in pawns.cpp: the chain bonus is an increasing function of the rank. This is an important feature, because it incentivises pushing pawn chains in general (pressure term, gaining space and/or creating king attakcs, and/or creating pa...

Re: Solving the KID

I played a game against SF 5, looking at the Of course, my question is also to the forum at large: how many engines see the below position as winning for white?
