Dragon defended this position bad and was lucky to get a draw. White had a won tablebase ending later on. [D] 4rk2/4b1pp/p4p2/1p1r4/8/5P2/PP3BPP/2R1R1K1 w - - 0 27 27.Bb6 was a very bad move in a drawish position (27.Rc2 for example). Ruffian got two connected passed pawns and won easily. [D] 2r5/5kp1/p3pn1p/2N1R3/1p4P1/7P/PPP5/7K w - - 0 29 Black is better but white should be able to draw the game after 29.Nxa6. 29.c4 +0.02 is not a good move with a completely wrong score. Michael
