Movei blundered by 69.Rxa5 that leads to drawn KRP vs KR and had to draw against knightX. [D]8/6B1/8/7P/R4K2/2pk3r/8/8 w - - 0 67 am Ra3 bm Kg4 Movei blundered by going to drawn KRB vs KR(again I did not check if Kg4 is the only winning move). [D]rnb1kb1r/pp2pppp/1qpp4/3nP3/3P1P2/2N2N2/PPPB2PP/R2QKB1R b KQkq - 0 7 am Qxb2 Movei blundered against Horizon by capturing the pawn. [D]5b2/5P1k/p1q3pp/4Q3/1p5P/5R2/6K1/8 w - - 0 59 bm h5 Movei missed h5 against kingofkings. h5 force a draw when 59.Qe8 probably losing. Movei against esc(not sure if it blundered) [D]8/5k2/R1N5/2P3pp/P3Kp2/2r2n1P/8/8 w - - 0 58 Movei forced 3 time repetition by 58.Kd5 Was it better to avoid the draw by 58.a5?(I did not do serious analysis to know and my Fritz8 gives positive score to 58.a5) Uri
