This position is from my Valentine tourney from round 20
Gambit 1.0 v Shredder 5. Gambit choose the rep by 48. Qh6
instead of what Shredder expected and appears to be winning
48. Nd7+ Qxd7 49. Bxd7 Nxd7 50. Qxa5 Bg6+.
After manually playing the moves Gambit sees white winning
but even to depth 18 will not play 48. Nd7+
The two PGN's from each follow. It should be noted that the Gambit PGN
shows the book as Ct.tbk when if fact in use is Gambit.tbk, this is an
interface bug.
Shredders PGN.
