Chess324 Tournament (Completed)

Post by Modern Times »

Back in January I ran a chess324 tournament, here:
viewtopic.php?f=6&t=81318

That was incredibly laborious - individual engine-engine matches one by one with all 324 positions reversed sides per pairing. Necessary because CuteChess won't run a gauntlet or round-robin in that way.


This time I took a different, less manual approach. I stumbled across Stefan Pohl's 3-move Chess324 books here. Another great initiative from Stefan:
https://www.sp-cc.de/anti-draw-openings.htm

I chose the Chess324_xxl_big_+090_+119 book which has 70355 lines. That meant that I could run gauntlets in the normal way. And being slightly unbalanced (evals per KomodoDragon 2.6), it made things more interesting.

The tournament is below:

I don't think there are any great surprises. Black wins at 4.6% and white score 68% reflect the advantage-for-white slightly unbalanced book.

Caissa 1.12 has replaced Caissa 1.11.

The result is a jump of 2 places in the tournament ranking - from 8th equal previously to 6th now - due to the approx +31 Elo improvement in performance.

Can you post all the 234 chess positions or Opening Book that you are using, where did you get the 234 Opening Book, did you created it yourself?

I should change the title, it is "Chess324 xxl" as created by Stefan Pohl. Not pure Chess324.

Chess324 xxl means: All Chess324 positions combined with 6 single-step pawn-plies
Example: 1. h3 h6 2. g3 d6 3. d3 b6
So more than 600000 different Chess324 openings were possible and evaluated!!!
The Chess324 xxl sets are around 30x bigger than the Chess324 64x sets...

I use this book
Chess324_xxl_big_+090_+119 = 70355 lines
