I would like to know because Nimzo7.32 moved of opinion regarding Qxc2. Could
be the learning function?

Below the Rebel-Tiger analyzes on a PIII-450 and HT=64Mb:

00:00:00.9	0,40	7	44021	Qxc2  Qb6  Qc5+  Qxc5  dxc5  f6  g6
00:00:00.9	0,28	7	77971	Qxc2  f6  g6  b3  Qc7  Rac1  Qa5
00:00:02.6	0,24	8	229124	Qxc2  Rac1
00:00:03.7	0,16	9	402564	Qxc2  Rac1  Qxb2  Qb6  Rd8  Qc6+  Ke7  f6+  gxf6  Ng3

00:04:35.2	-0,06	13	31039778	Be7  Nc3  0-0  Rac1  Qa5

End of depth 13 aproximately 6min.
