[D]7k/3r3p/6P1/8/1BKR2N1/6r1/8/8 w - - 0 1 In this one, also by Troitzky, Fritz 5.32 and Fritz 6 (old) don't play g7+ because they don't know that KRB vs. KR is a draw, so they play Rxd7 with an eval of +2.xx. F6a, Shredder 4, Nimzo and Crafty pick g7+ quickly, while Tiger, Hiarcs and Junior have to find it through search and take much longer.
