Andscacs - New version 0.92

[Tony P.]

I'm not a chess expert... how can Black try to make any progress in the following KRPPvKRP (it starts at move 53)? The only pawn that can be passed is the h-pawn, and the fact that it's a rook pawn decreases the winning chances dramatically, as a rule of thumb. Yet, both engines evaluated it as about -1. The Lomonosov 7-men TB confirms that it's a draw.

It looks like Andscacs did nothing wrong in the whole game (40/9 TC, corresponding to CCRL 40/4) - it was just drawish throughout (in particular, after Black committed to 14... Nc5 instead of 14... Qc7, both leading to an equal position, neither side could afford to avoid the opposite colour bishops) - but it made me think about engines' imperfect rook endgame evals.

Yes, it should be possible to code something about this concrete endgame, so it is recognized as drawish. Thanks.

[BrendanJNorman]

I'm not a chess expert... how can Black try to make any progress in the following KRPPvKRP (it starts at move 53)? The only pawn that can be passed is the h-pawn, and the fact that it's a rook pawn decreases the winning chances dramatically, as a rule of thumb. Yet, both engines evaluated it as about -1. The Lomonosov 7-men TB confirms that it's a draw.

It looks like Andscacs did nothing wrong in the whole game (40/9 TC, corresponding to CCRL 40/4) - it was just drawish throughout (in particular, after Black committed to 14... Nc5 instead of 14... Qc7, both leading to an equal position, neither side could afford to avoid the opposite colour bishops) - but it made me think about engines' imperfect rook endgame evals.

As a rule of thumb, in single rook endings where all pawns are on the same side, the position is a draw with best play.

The less pawns the easier - this one is child's play.

I suppose engines lean toward the "yeah its true, but if anyone can win, its black" mentality.

Most strong humans recognize it as a drawn ending immediately though.

[JJJ]

I wish you the best for this TCEC daniel, I m sure your engine will perform well. It seems as nice as you always are.

[abulmo2]

Congrats on the release and the strength improvement!

One interesting change that I want to comment, but interested people will have to work the details for themselves, is that it now saves two moves to hash.

This sounds excellent! Have you ever experimented with saving more than 2 moves per position? If so, did it work well?

Thanks. No, I have only tried with 2. I have not enough room for more in the current hash.

In Amoeba, I also save two moves per hash entry. If two moves made a (small) difference over a single move, saving three moves per hash entry was neutral in my SPRT test.

[Frank Quisinsky]

Hi Jose,

good news!
Thanks for your wonderful work!

Best
Frank

[Paloma]

Many thanks Daniel and good luck in the forthcoming TCEC S10

[Dokterchen]

Awesome progress! Thanks you Jose!

[JJJ]

It seems now than Andscacs might have reach the level of fire 5 ! That's nice !

[Tony P.]

There's Fire 6 to be released within the next few weeks, though.

I wish all the TCEC participants to play chess at a level as high as possible Thanks for the upgrades!

As a rule of thumb, in single rook endings where all pawns are on the same side, the position is a draw with best play.

Yes, exactly.

That said, today I read a long response by Tord Romstad on rook EG eval in SF, and it's perplexing - the addition of special handling of rook EGs doesn't improve the overall Elo because it's computationally expensive and the time is better spent on searching more nodes despite the engine misevaluating EGs arising deep in the tree.

Computer chess is probably still rather about brute force than about correct eval.
