Re: What's up with this endgame?

The lesson for me here was about endgames with same-colored bishops being won for one side (no matter what engines say) Perhaps you have already realized this, but this non-drawish tendency is specifically about same-color bishop endgames with weak pawns (usually one weak pawn isn't enough) unable ...

Re: future of top engines:how much more elo?

A fun engine idea: Start out playing like full-strength Stockfish (in order to win some material) and then use near stalemate positions and self-smothering to force the opponent to checkmate it.

Re: What's up with this endgame?

My impressions and with using some backward analysis, you had totally equalize with move 28. Bd6 - always a good time to offer draw here ;>) The first weakness was 29 ...b5 which allowed Qa5, the next series of moves are pretty much straight foward, but 36.. Ra1 was not the best move I'm afraid. Af...

Re: What's up with this endgame?

You were lost after 38. .... Bxb4. If your opponent would have played 39.Kd1! the game was effectively over. I agree that Kd1 is a better move. However, what actually changes after Kf2? I have not looked at this in depth, only for a few minutes. In either case, white is marching the king to the que...

Re: What's up with this endgame?

A similar (but much simpler!) position occurred a few days ago in the US Junior championship game Li-Cervantes, and even in this simplified position, it takes SF a while to realize that black is winning. 8/4b1k1/4p3/3pPp2/3P1P2/4B1K1/8/8 w - - 0 51 (the conclusion to the game can be seen here: https...

Re: Chess & The Future Of Computing..Where Now?

Also, if you are doing analysis instead of using your engines to play other people's engines, a 2060 instead of a more powerful RTX card is more than good enough for most people. Even a 2060 will use up all of your RAM fairly quickly, so unless you analyze many positions, extra power may be overkill...

Re: buying a new computer

I am looking for a new computer since it has been a while. I saw a 2990wx with 16 GB ram, 2080ti, 500 SSD drive for 3k. Overall do you think this is a reasonable deal? Will this be a good setup for a few years? I know new chips are coming out, but will this be good "bang for your buck"? I know a fe...

Re: Any engines solve this one?

Fantastic position! I think the main problem for Stockfish is that it doesn't see Bxh7 and Rxg7 sac from far away. Even if you click the moves it takes a while to realize this is winning. Leela is clueless a well even if you show it both Bxh7 and Rxg7. Would you mind sharing the opening moves? I th...

Re: Why there is no interest in Computer with odds Vs Humans match?

Perhaps with a sufficiently lost position, the whole concept of evaluating in terms of win probabilities (derived from games where mistakes are made sometimes) is more fruitful than the AB approach of attempting to delay checkmate for as many moves as possible. This will look like a "bluff", but at ...

Re: Whatever is current - Amazing Leela

I think that falls outside of the scope of this thread (where I've been claiming you should focus on the relevant chess lines instead of generic chess lines, so if it's "not played as often in engine tournaments" that means the line is generic), but, sure, I'll see what I can do about those lines a...
