OpenTal v1.1 by Paweł Kozioł
https://github.com/bcm314/OpenTal

Not a new release but new compiles
"My head is filled with sunshine.
In the first game of my match with Botvinnik I will play 1.e4.
And I shall win."
Mikhail Tal (1936-1992)

OpenTal 1.1
OpenTal is an open source UCI chess engine that emulates weird and wonderful chess of "the wizard of Riga" - Mikhail Tal. It is based on Rodent, and
probably plays at 2500-2600 Elo level. The exquisite tuner of chess engines, Brendan J. Norman, transformed all the missing rating points into pure style.
OpenTal will sacrifice material, turning the chess board into a world of chaos, and will mount a reletless pressure on its opponent's position.

Against decent engines, OpenTal will overpress and lose. However, it is not meant to play against engines. It is meant to play against you. Install it under
Winboard or Arena, and go against one of the greatest attackers of all time. No tweaks, no options, only Tal inside!

OpenTal has a couple of quirks. You can supply it with a modern opening book, but it will consult internal book made out of Tal's games first. Its evaluations
are notoriously unrealistic and optimistic. It wants to win and expects it to happen.

Version 1.1 has been released on 2018.01.05. It uses unchanged eval, slightly better search and is capable of conducting a multi-pv search. This means you can
actually analyze with Tal!

A very strong (probably already top 20-25) program developed since end of '22.
Tested in an own OpenBench instance
https://chess.drpowell.org

A close version compiled by me was already playing in Carlos blitz tournaments here:
forum3/viewtopic.php?t=83657

In a recent own test with (just) 1200 ultrafast games it came just around 100 rating points below Obsidian 12.0.
(results and pgn in my download - this was a version slightly before release, but release version increased nps by roughly
10% due to some last code changes!)

As there are no win compilations for now, I made an avx2 and a sse4.2/pop compilation available.

More compiles (author's) here:

https://github.com/jeff-pow/Titan/releases/tag/v1.0.0
Which don't work here at least - issue extended
Hi Guenther

I too am having issues with author's compiles of Titan, as the the engine refuses to load in Fritz GUI.

Do you know if there is any solution to the problem ?
