Connie in an effort to Blitz her way out of defeat quickly replies with...

putting all of her pieces on dark squares rendering the White B impotent

I play 51.Qd7+. At first I wanted to play 51.Kg2 but then the plan of ...N-f7-e5 looked like a clear improvement of Black's position. So I should focus on keeping the knight from reaching e5.

I play 52.Bd3+. If Black blocks with the pawn at least I'll have a target. I think it is likely that zugzwang may play a role soon, it may be the key to winning. I still have the problem that even winning knight plus "f" pawn for the bishop is not enough to win. I do expect to win, but I don't know if the position is won yet against perfect defense.

Guessing the Connie will push the f-pawn creating another weakness, the simple 53. Kf2 should begin to bring the game into it's final stages aiming for Zugzwang.

Once again Connie blocks + by advancing her P with...

52..f5

I play 53.Kf2, giving the option of going to g3 or e3. Now Black could consider the maneuver ...N-e4-d6 to centralize the knight, but Connie won't play this as I could win a pawn by taking on e4 and checking on e6, although I wouldn't do this as the resultant ending looks drawn.
