It means that Junior outsearched Fritz by some plies Here is the evaluations of the programs: 58.b5 1.94/14 50 58...Qd5 1.30/17 14 (kh6) 59.b6 2.69/13 26(Qc7+) 59...Rxg2+ 1.57/16 1:55(Qe5) 60.Qxg2 5.78/14 17 60...Qd6+ 1.57/17 41 61.Qg3 1.66/16 1:01 It is clear that Fritz did not see the tactical problem with Rxg2+ when it played 59.b6 and it found it only at move 61. Fritz expected Qe5 when it played 59.b6 based on the pgn and even after 59...Rxg2+ it could not see the problem based on the evaluation inspite of the fact that it searched 14 plies when it searched only 13 plies for move 59.
