OpenTal - almost new engine

Post by PK » Sun Dec 17, 2017 7:53 pm

Since the next Rodent release will be delayed, I decided to present you a program with a proud name "OpenTal 1.0"

http://www.pkoziol.cal24.pl/opental/

In short, this is a shameless Rodent clone that does not expose tuning options to the user. It plays in one style only. To make matters worse, it uses internal opening book before main book. And the entire project hinges on evaluation weights kindly provided by Brendan J. Norman.

These weights are magic. OpenTal still plays at about 2500-2600 Elo, despite sacrificing pieces right and left. Despite apparent craziness it managed to beat RedQueen 1.1.98 in a short match. It won a couple of games with a direct attack, plus one crazy endgame rook down. It also lost a few because of unsound sacrifices.

OpenTal will lose to anything over 2800 Elo, especially untweaked Rodent manhandles it really badly. But this is not an opponent for engines. This is an opponent for you!

Would love to be able to weaken the engine by nps setting or to around 2000 elo

Weakened agressive personalities will be accessible within the full Rodent package. The whole point of OpenTal is to play against Tal at full strength (a young one, with both kidneys functioning) and get clobbered like that:

Nice, but not really Tal-like, because the sacrifices are sound!

These sacrifices work against humans or weaker engines. Default Rodent has beaten poor OpenTal like 19 to 1. This is even more than their rating difference, because search code is basically the same. These games were also entertaining in a way: most of them featured a declined sacrifice or a counter-sacrifice.

Re: OpenTal - almost new engine

http://www.pkoziol.cal24.pl/opental/

In short, this is a shameless Rodent clone that does not expose tuning options to the user. It plays in one style only. To make matters worse, it uses internal opening book before main book. And the entire project hinges on evaluation weights kindly provided by Brendan J. Norman.

These weights are magic. OpenTal still plays at about 2500-2600 Elo, despite sacrificing pieces right and left. Despite apparent craziness it managed to beat RedQueen 1.1.98 in a short match. It won a couple of games with a direct attack, plus one crazy endgame rook down. It also lost a few because of unsound sacrifices.

OpenTal will lose to anything over 2800 Elo, especially untweaked Rodent manhandles it really badly. But this is not an opponent for engines. This is an opponent for you!
Fantastic stuff, Pawel & Brendan. Thanks a lot, fellas :) Can't wait to try it out. :D

Cheers,
CL
