Vas is ready to make a commercial business with Rybka. >Can you imagine how much damage your post may wreak, to Vas's future business? You are overreacting a bit here. Let's put everything in perspective. a) Rybka is an original engine and programmed by Vasik. Just already testing with it and after some days i figured out, note i do not dissassemble at all as that's illegal i just test a few positions at it and see how it reacts, i figured out it is a very unique program. I was amazed that what i tried myself in 1999 works so well for Rybka. He sure has tuned it very well! An amazing achievement. Though positional weak, it kicks butt strategical and tactical in a way we have not seen before! b) Rybka is freeware engine, so until he releases 2.0, you will do near to no financial damage in a forum with under 200 visitors or so, from which majority is not gonna buy anything anyway, except for chessmaster and fritz. c) what rybka is doing bitboards or 32 bits doesn't matter a shit. In fact i feel bitboards only slows it down there at the moment as it requires a 64 bits executable for bitboards. d) gcc is indeed ugly compiler according to some, but it's pretty ok for 32 bits code, like Diep. In fact it's faster for diep than visual c++. I hope you realize visual c++ 2005 compiles somehow do not work for me at quad opteron with server enterprise at it, when i tested it. Those exes do work at dual opterons and single cpu opterons though. So gcc is not a bad choice there. e) royalties made very few people rich f) Rybka is for sure currently strongest single cpu engine, no question about it. Whatever you say, that's not just taking over piece values from Fruit, that's a whole lot more than just that. g) Could you by the way explain to me how to use fruit mobility in a piece square table program?
