Questions in Respect to Code Release

I am going to release my engine sometime this month. Unfortunately I have never released code and also didn't originally write my code with the intention of releasing it or having it run on any machine aside from my own. This leads me to a few questions. I also suspect I might have more questions be...

Re: Will a human ever make 2900?

It might have been more interesting, but honestly I think Anand today is stronger then Fischer was most of his career. As previously mentioned however its a completely unfair comparison. Computers have massively improved human play in my opinion. The focus has also shifted, other traits have become ...

Re: Sweet, sweet home

I wouldn't waste too much time on specific PST values in different engines. The reason for this is that most likely the values in strong engines like SF will not be the result of some developer thinking a specific variable should be some specific value but much more likely is the result of some auto...

Re: perft(6) after e4 e5

Could you give the us the PGN of the game that failed? This evening I'll likely have time to run some perft tests that might prove useful for you.

Re: perft(6) after e4 e5

If you suspect you have a bug in move generation, I can recommend downloading the latest stockfish version and starting it in a terminal (not in a GUI). Then manually enter the position via UCI protocol and call it's perft function, which is extremely fast. The reason I suggest this is that SF actua...

Re: Knight Evaluation

Hi Lyudmil! Your evaluation terms seem to mostly be similar to mine (obviously there are many more terms one could and should consider) so I won't comment on those. I think it's an interesting thought that you could avoid a complex evaluation function for knights by evaluating bishops more precisely...

Knight Evaluation

First off I don't know what other engines implement in their evaluation functions, so if what I am writing here or in another thread yet to be written on piece mobility is common knowledge then I apologize. For reference the chess-programming wiki already mentions quite a few standard evaluation ter...

Re: Schlechter - Wolf

I agree out of a human perspective I wouldn't want to take the rook unless I had to. The only troublesome thing for me seems to be the knight on h7, which is awkwardly placed to say the least.

Re: Forward Chess Application

I don't use it myself but a friend of mine does and at least was very happy with it last time I saw him.
