Re: Checks and move ordering

I have been working on my move generator and now I know if a move gives check before I make it. Now I am wondering how I should use this information in move ordering, e.g. should a winning capture that gives check be tried ahead of winning captures that appear to gain more material, or should disco...

Re: How to interface to chess engines.

It has been several years since I was last on this forum, so apparently my old account expired and I had to sign up again. I am interested in writing a program to interface to any chess engine for the purpose of doing chess analysis. I want to create a large database of tactical problems derived fr...

Re: Speedup with bitboards on 64-bit CPUs

I would not expect any speedup from bitboards compaired to mailbox, even in 64-bit mode, if you jsut use them to replace the move generator. For bulk move generation bitboards cannot beat mailbox. They are very much faster than mailbox for generating moves selectively (e.g. only captures, only chec...

Re: Speedup with bitboards on 64-bit CPUs

I think it has been reported here Rybka, which Vasik says uses bitboards, runs about 60% faster on a 64 bit processor. I think the speed difference will depend greatly on what is being represented with 64 bit values. 60% is a lot, but of course we don't know exactly what Rybka is doing. Does anyone...

Re: Software for Printing Games/Positions?

I've seen a fair number of questions about chess databases and such here, so please forgive the intrusion if it is one... I am looking for some kind of software that can take a file of PGN games (or some other set of games) and prepare them for print with a diagram of the final position at the end ...

Re: My draw with an FM on ICC

How could an FM miss that in a game 15 I wonder? Anybody can suffer "chess blindness", even the very best players. Possible, but it would seem dubious, I've seen and played combinations of that complexity often at G/5 and and even G/2! You must be very strong to be able to play Rxh7 here in only a ...

Re: Compiling PSWBTM (to Pradu)

Hi Pradu I have trouble compiling PSWBTM with Microsoft Visual 2005. What version of wxWidgets and Visual should I use ? It seems that according to nmake some targets in your makefile are missing (all-before for instance) so i tried to start from scratch in visual with an empty win32 project. In va...
