Thanks Vincent. I got it know. Actually I get +5 score now after 3. Bg3. But now Yace suggests 3. c6. I don't find a win here for black. Can you suggest a line? I tried grabbing the a-pawn, then going with black K to f5, then pushing a5. Black will capture on a5 with the bishop, and give the g-pawn for free. [D] 3B4/8/p5p1/1p1b1kP1/1P6/4Kp2/8/8 b - - a5 Bxa5. And from here, I cannot find progress. Of course one can push the g-pawn a bit, But I didn't find more. Can you, or anybody else show a line?
