Only four games in my strong humans book, 50% score, and a losing score for White in six games in the Hiarcs powerbook (mostly engine games). Grandmasters would say Black has full compensation here. Whether White or Black is "better" is very hard to say, but the score should surely be quite close to zero, since even if White is for choice he has nothing like his normal first move advantage.Laskos wrote:Good catch! Komodo too evaluates that as very close to 0.00, sometimes even small Black advantage. I think most strong humans would prefer White.Lyudmil Tsvetkov wrote:

SF thinks black is better here, I guess Komodo would assess it similarly, when actually the advantage is with white.
[d]r1bqkb1r/pp3ppp/2n2n2/4p3/2P5/3P4/PP2BPPP/RNBQK1NR b KQkq - 0 2
white has small, but clear advantage
the game is still a draw here, but I don't know why you would consider giving -20cps score instead of +20cps a good evaluation?
those are full 40cps, almost half a pawn.
of course, c4 by white was weak, white has much better than that, but the point was to show some real-life examples, and this position was suitable.
you would be surprised to know that in each and every game one side has a pawn or 2 more, with other material being equal, Sf and Komodo would almost always display wrong evals.
for a human, that is evident.
I know very well you are proud of the way you managed to make Komodo play less materialistically, that is what actually made Komodo strong and is a distinction to other engines, but for such positions engine evals are clearly off.
