boards away, I did not see it and missed out on some useful knowledge going
into the game.  Steve assumed I had, and so he was looking to vary at some
point -- which is probably what inspired the brilliant sac he came up with.})

the b-pawn.  After all, having said A, Black must say B.  But I thought the
Knight sac with Nxd5! was scary.  After the game, Steve could not demonstrate
a win for White to either of our satisfaction, and Fritz seems to only come up
with a draw as well.  But a little looking through the following variations
suggests that it isn't something I'd want to venture into over the board, so I
probably made the right decision.  Here are some lines:} 13... Qxb2 $1 14. Nxd5
