can chess program see win for white after e4 h6 d4 a5?
Posted: Tue Mar 30, 2010 11:22 am
I wonder what is your opinion:
1)Is it correct that white objectively has a winning position after these 2 mistakes by black
2)Can chess program see a winning score based on deep search(the important thing is not a big score for white but seeing significant increase in score)?
3)Does white always win in comp-comp games at long time control between top programs(Naum4.2 Stockfish1.6.3,Rybka3,Firebird1.2)?
4)What is the best plan for white?
Is it Nc3 and Nf3 or maybe it should include at least one of c4 and f4 that fide master suggested in discussion in the following thread

Some analysis by Rybka3 does not show a significant increase in score but of course more time is needed and if somebody with good hardware can give chess programs 24 hours to analyze then it may be interesting.
