Go up one level in this thread

Very interesting and deep analysis.

A few additional notes:

1.) The Fritz mainline probably simply transposes:

19.Qf1 Nxe4 20.Qf4 cxb2 21.Rh5 Nf6 22.Rh6 Ne4 23.Qf5 Ng5 24.Qg4 Be4 25.h4 + -

2.) Fritz has no clue this position can be won.

Its decision is obviously based on the easy draw it can get in this line.

3.) I suspect many programs will see the possible draw after a long search -
1.Qf2 should be just as good as 1.Qf1.

Some output of "Der Bringer" on Athlon 1.33:

0:12:41.2  (14/41)   195699042  -0.27  Rg5 Rxf7  (Mat=-235,50=0)
0:16:14.3  (14/42)   253463460  -0.26  Qf1  (Mat=-135,50=1)
0:19:53.3  (14/42)   316068616  -0.16  Qf1 Nxe4 Rh5  (Mat=-235,50=1)
0:32:02.6  (14/44)   511646825  -0.15  Qf2  (Mat=-135,50=1)
0:35:39.2  (14/44)   571380871   0.00  Qf2 Nxe4 Qf4  (Mat=-235,50=1)
0:47:09.2  (15/47)   760060287   0.00  Qf2 Nxe4  (Mat=-235,50=0)
