Subject: Difficult Test Position(Takes Chessmaster over 12 hours to see Draw)

The following position is from the Kasparov -Kramnik match (London 2000)
[D]Q/8/5pk1/PpP3p1/6n1/3qB1PK/1P3P2/8 b
In this position Kasparov played 62...Qf5 and later drew .For some reason this
move is hard to find even for modern chess programs and fast hardware.It takes
12 hours and 50 minuties for Chessmaster 9000 on a 1.8 gig machine to find
62...Qf5 and with it a 0.00 score.It does this at ply 16.At this ply it gives
the PV 62...Qf5 63.Kg2 Nxe3+ 64.fxe3 Qc2+  65.Kh1 Qd1+ 66.Kg2 Qc2+.
Please indicate the result for your program.
