Hi folks, I've been playing a no-opening book tourni, just to see how the engines handle the opening stage of the game without a book (there four positions, involving first moves of e4, d4, c4, or nf3). I'll post the results soon, but here is something i've noticed. Rybka loves to fianchetto its kings bishop, and is more willing to get itself into a hypermodern position than any of the other engines. In contrast, when the other engines play each other, you get positions that look more like what was played in the 19 century by people like anderssen (you know, old forms of the guico pianos, or scotch game. crazy tactical positions, etc. Engines other than rybka want to be DOING something, NOW) Here is a game currently running with fruit as white and rybka as black. fruit thinks it has an advantage. Rybka thinks its about even 1. c4 (now out of book) nf6; 2. nf3, g6 (does any other engine play g6 this early without book help. maybe hiarcs hypermodern?). 3)nc3, bg7, 4) e4, (grab the centre. Every engine does this early except rybka sometimes doesn't) 4)....0-0 ; 5) d4 c5, 6) d5, d6 (rybka gets into a lot of kings indian formations when you don't use book) 7) be2, nbd7; 8) 0-0, a6; 9) qb3, b6; 10) bg5, bb7; 11) h3, qc7; I am looking forward to rybka being able to inform opening theory, rather than just following it. What would you folks rate this position? Does white have a solid +.6 advantage as fruit 2.2.1. thinks, or is it equal, as rybka thinks? best joseph
