Re-tested 6b to make sure my output was right:

Bird,S - Fritz 6
r1bqk2r/pppp1Npp/8/2bnP3/8/6K1/PB4PP/RN1Q3R b kq - 0 1

Analysis by Fritz 6B:
12...Qe7 13.Qxd5 Rf8 14.Rf1 Rxf7 15.Rxf7 Qg5+ 16.Kf3 Qe3+ 17.Kg4
  -+  (-1.88)   Depth: 12/36   00:00:55  14346kN
12...Qe7 13.Qxd5 Rf8 14.Rf1 Rxf7 15.Qxf7+ Qxf7 16.Rxf7 Kxf7 17.Nc3
  -+  (-1.78)   Depth: 13/40   00:02:25  38418kN
12...Qe7 13.Qxd5 Rf8 14.Rf1 Rxf7 15.Qxf7+ Qxf7 16.Rxf7 Kxf7 17.Nc3
  -+  (-1.69)   Depth: 14/42   00:07:12  113611kN

(Bird, Scarb 01.09.2000)

Still not there so I assume it will take roughly same as first post.
So seems to me clearly in this position 6B is slower.

Thanks.
