Re: Alpha Zero's 21. Bg5! revisited

Well, than don't come along with 3.59 for the one and 4.59 for the other one to prove, they are both equal. If they are, why then the difference in eval, if the difference doesn't matter (to you), why than does it prove from your side, the moves are equal? You didn't answer when I asked "If you ass...

Re: Alpha Zero's 21. Bg5! revisited

If you don't do so, you'll have to prove b4 winning in less moves on corr.- games of some quality. No, I don't have to because that's not what makes a move better when playing a normal game of chess where winning is all that matters. All winning moves are equally good. I'll grant you that there is ...

Re: Alpha Zero's 21. Bg5! revisited

It's a bad test position if you only consider one move to be the right solution (which is the case for most test positions and was an assumption for this one). If you assume that +4.6 and +3.6 are valid evals from SF at depth 66, what average results do you expect after Bg5 and b4 for 100 correspon...

Re: Alpha Zero's 21. Bg5! revisited

So you say b4 is better? No, I say that they are very likely equal. I mean, if you have to choose as a chess player, having seen many good lines after both moves, forgetting about "test positions" and their very many all subjective definitions of them. Want to play b4 with White in a corr. game? In...

Re: Alpha Zero's 21. Bg5! revisited

You don't like mate in x- problems, do you? And I know this one isn't one, but if you aren't able to find the mating distance for sure, won't you try to have other ways to dinstinct a good and probably winning move from a better one move winning with even more probability? And if you think a move w...

Re: Alpha Zero's 21. Bg5! revisited

Well, even if there were more then two moves leading to a win, there must be always one of them the best one. My bets are on Bg5!. Why? A mate is a mate, doesn't matter in how many moves. You don't like mate in x- problems, do you? And I know this one isn't one, but if you aren't able to find the m...

Re: Alpha Zero's 21. Bg5! revisited

Correct, Bg5 is the best move. Well, since b4 is +3.59, 99.9% chance they both lead to a win. So it's not really THE best move. It is just one of at least two winning moves. Well, even if there were more then two moves leading to a win, there must be always one of them the best one. My bets are on ...

If there is interest, I can generate some compilations for Windows / Android users.
Great news, thank!
Windows SSE4.1-popcnt would be great.

Re: Can we train a NNUE net for playing unbalanced game?

Stockfish uses the NNUE evaluation when the position is balanced, then move on classical evaluation when the position is unbalanced. Why does this happen? Can we train a particularly effective evaluation net for unbalanced positions? A net with intrinsic contempt! You haven't read about dkappes net...
