PHCEL

Post by Rubinus »

Tournament with all opening moves. 1.g4 seems to be really lost, 0:28 so far, and no surprises in the form of White's gains in the remaining two games. Yet 2.5 years ago Stockfish didn't lose a single game, here White has lost all four so far. Coincidentally, today is Mr. Grob's birthday!

Next 1.f3. Estimate around midnight CET

90+30, Intel i7-12700H, no ponder

Ideally a disturbed balance for the stronger to assert themselves.

More boring than last time. Seems like it will be all draws until the best moves are played at the end, there might be a favourite somewhere.
