Cool tournament, thanks for including weiss

Weiss shows a nice progress last weeks. We are waiting for new versions

Thanks for testing the new version of Fab, very impressed by the results!!!

I will include Fab 1.16 to a new tournament with much stronger opponents such as Minic (non-NNUE), Winter, Combusken, Demolito, Pedone, Lc0-CPU (and may be even stronger: Roc, Defenchess. RubiChess, Nemorino (non-NNUE), Schooner, Booot) etc. That would be a really tough testing for the new Fab and other rapidly progressing engines (such as Koivisto 4.0) at an ''almost elite party''. The tournamed will be called ''Winter is Coming''. I will report the results in approx. one week.

Thank you for organizing this tournament, and thank you for your interest in my little engine Orion

Nice, thanks for involving various versions of Francesca. Note that the difference between 0.29 and 0.29a is just a bugfix when pondering is on.

I know, but in my previous tests 0.29a was weaker than 0.28. I suggested that something was wrong with 'bugfix' and tried 0.29. Unfortunately (and surprisingly), the same tendency in comparison with 0.28

Thanks for including both versions Seer in the tournament! It's very exciting to see the improvement going from 1.0 to 1.1.
