Open Swiss Tournament 40/40 (4CPUs)

[Sergio Martinez]

Wow, what a swindle. Quark has a bug that also used to be in Myrddin long ago. It fails to see if the move that would result in a 50-move draw also results in checikmate.

Thanks for the tournament, Sergio!

Yes its true

but it really loses the game a few moves before, the losing movement is 145. Qb4...

Thank you very much John

[JVMerlino]

Actually, it turns out that the losing move was before that. I should trust Myrddin's eval.

[D]8/6pk/5p1p/5P1P/4q1PK/4r3/6RQ/8 w - - 78 137

137.Rf2?? loses, and Myrddin's eval jumps up to +4.5 (from the +2 that it was before then, due to very crappy king safety eval terms).

Thanks Sergio, This is the first result in which RomiChess P3n performed up to potential. Finishing with 5 points tied with Floyd and the rest in that group is not bad. And just to show that it is not a fluke here are Romi's results against Floyd on HGM's ICS server.

Floyd : 6 (+ 3,= 1,- 2), 58.3 %

Romi has the +3.
