In the first game, CM just continued to get a better position. However, 35.Rb1 is a disaster -- CM's eval jumps from about -1.3 to -8.5 with that move. Additionally, 31.Qxa7 causes an eval jump of about 0.5, 34.Kf1 also causes a loss of about 0.3 points. The ending position is a Mate in 6. In the second game, CM likes the position right out of the opening, giving it a +0.75 eval. But Kamberi fights back nicely and by move 16 the eval is almost zero. However, by move 20, the eval is back up to around +0.7 again. The position at Black's 26th move is an excellent test position. There are four ways to take back. Which is best? [D]r1b1r1k1/1p3p2/2p1nq1b/2P1p1pp/1PB1PB2/2N1QN1P/3R1PP1/1R4K1 b - - 0 26 CM thinks Nxf4 is best (eval -0.13), and the move chosen by Kamberi (exf4) is the worst of the four (eval 0.68). At the end of the game, the eval is only about 1.60, but as of 47.Bd5, White's passed pawns are too strong. jm
