(Considering the handicap, I too would have played F2 rather than resigning, but it's still worth mentioning that)

Now Black wins even if it's White's turn again.]

G4 would have won locally, rather than needing to climb to D8+H8.

Now White can connect F2 to the K-edge, since I9 gives a ladder escape.

Black is still winning, but White can make that win require the A1 corner.]

I probably would've just kept this part of the board simpler, although I guess White may have been hoping that Black would waste a move here, so that White would get the A1 corner too.]

This wins without the A1 corner.];W[h3]

Now Black plays H5 or I5, and in each case, connects via G5 or to H8.]
