One of the interesting things about Twixt to me is that, despite all the chaos, clever moves, and tricky endings, the idea of "having the upper hand" still exists, and it is possible to just check a few variations to get a sense of it. The better you are, the fewer variations you have to check. In this game, it looks like White has the upper hand by move 34. It would be interesting to prove that wrong.
Diego's suggested line: |34.i535.f536.h737.e838.f8 is of course followed by 39.d6, or White would lose immediately. Then Black makes good on his threat and creates the gauntlet with 40.h9. Now White has the first-mover advantage, but has a lot of empty space to cross down the left side. The immediate threat is F10, so White can't go far on the next move; 41.e13 is about as far as he can stretch. That actually looks pretty good. Let's feel it out:
|34.j8 35.h11 36.g12 37.l9
|36.l4 37.j7
|36.j4 37.n4
|34.j9 35.l8
|34.i7 35.i8
|34.i7 35.i8 36.k10 37.k9
|34.i5 35.f5 36.h7 37.e8 38.j9 39.f13
Correct?
But what if |34.i5 35.f5 36.h7 37.e8 38.f8 ?

I don't see a victory for Black in there, but I could be wrong.
I was actually thinking of |34.i5 35.f5 36.h7 37.e8 38.f8 39.d6 40.h9 41.e13 42.g16 . Your line looks interesting though.
