"Peasant Revolt" Endgame Chess

[Uri Blass]

A small rating list of top 10 engines at Blitz 360''+ 3.6''. The error margins as shown in Ordo are really 1.7-1.8 times smaller using pentanomial variance. Syzygy 6-men in use for engines supporting them.

Observe the underperformance of Stockfish in this disbalance, although it used Syzygy 6-men from SSD.

I think that you observe underperformance only because you compare stockfish with Komodo or shredder.

It seems to me that the difference of stockfish from houdini is higher

Fern, do you have something like a link for me to somehow track it?

Btw, I hope your health is better, and even better with a glass of wine.

I am not sure, but I guess that all in all, compared to performance from regular openings, Stockfish underperforms, and Houdini underperforms even more.

Got it this morning to the door, many thanks! Already saw some new to me Greek and Roman "orgies"

It seems the things have changed with Houdini 6, though I tested at short time control:

Brainfish is just a very fast compile of Stockfish, no Cerebellum book or this stuff.
