I do not think that White has a won game after 29. Nxb1, but he does after
Black's blunder 29 ... Qb8? That's the killer mistake (or so it appears to me).
I quickly checked this with Junior 6a (PIII 500MHz) and it immediately shows a
large advantage to White after Qb8? Whereas after 29. Nxb1 the edge was only
about .9 to White. After ... Qb8, the edge jumped to 2.48 after 2+ minutes of
search.
