Yace can see that white is winning after seeing the right moves. I told it 1...Bxg2 2.e4 f5 3.gxf5 exf5 4.a7 fxe4 5.d4 quickly and took the move back slowly. After doing it Yace's main line is 1.Bg2 Bxg2 2.e4 c4 3.a7 cxd3+ 4.Kxd3 f5 5.a8Q Bxe4+ the score was only +1.43 for white so I took these move forward and took them back slowly and it could see score of 3.40 when it returned back to the original position. Main line after all this learning is 1.Bg2 Bxg2 2.e4 f5 3.gxf5 exf5 4.a7 fxe4 5.d4 exd4 6.a8Q with 3.40 pawns advantage for white Uri
