Hi everybody. I've been away these last months but I'm here again and I still burden you with this subject. Smile

I tested persistent hashes at LSS server so far. It's a great correspondence games server and I recommend it to anybody who's interested to play correspondence chess for free.

I'm using the persistent hashes feature of SugaR (original code by Daniel Jose, based on an idea by HGM) and the performance is:

+19 =57 -0

I played 4 games against players who don't like engines, but all other wins were against 2000+ ELO players, so I consider this result really significant. The best opponent has been FIDE GM Igor Kovalenko, and I got +1 =2 -0 against him, but to be honest the win was due to a blunder in opening so I'd say I drew against Kovalenko.

I invite, again, the top engine programmers to reconsider the idea to include Daniel's code as an UCI option. It doesn't hurt anybody if it's an option...

Bye,
Rodolfo



With or without persistent hash...
is this an entirely unexpected result against human opponents?
