invitation to a new deterministic no opening tournament

[Uri Blass]

What's that? You promised that "it [RubiChess] is too slow to participate in my tournament".

Unfortunately I did not find faster candidates to win against stockfish 3M nodes per move or berserk 5M nodes per move but maybe I did not make enough tries.

I may try later stockfish developement version but unfortunately it has no contempt and I will not be surprised if it get only draws even with 100M nodes per move.

stockfish developement version could win with 100M nodes per move
