Bb5 wins.

bought Ṁ0 of YES

g4 has the best stockfish evaluation (assuming I didn't mess up the analysis board)

bought Ṁ50 of NO

@jack depends how deep you go. I think g4 leads to a quicker queens trade, which benefits black.

bought Ṁ95 of YES

@deagol Hmm, it ran to depth 36 for me and it toggled from preferring g4 to Bb5 and back to g4.

predicted YES

Of course, stockfish might not be the best evaluation to use considering we're playing against sf-3, but considering how bad at chess I am I can't do much more than blindly follow stockfish

sold Ṁ6 of NO

@Jack2 as a said, both might evaluate similar with perfect play, but keeping the queens on the board makes a big difference against a crappy opponent who’s a piece and more ahead

bought Ṁ1 of NO

@Jack2 also consider your (alt’s) profits
