I think F6 or E7 or D8 would be better.

(A corner move or the center.)

;B[e6]C[Eric\: It's better for Black to play in the wide-open corner, say at h7.

I sometimes  try this sort of block, but I think White has too much room on both sides here.  I guess I suggest i7 instead.]
  ;W[g7]C[Eric\:


I had to try some lines with ghosts to be certain about the A-edge, but can now prove that White wins.

White keeps this win for the rest of the game.]

 (;B[h8]C[Thomas\: Does Tom's move work here?

Peter\: No, because Tom's move is for parallel ladders on the 2nd and 4th rows, not 3rd and 5th rows. (There is a version of Tom's move for 3-5 parallel ladders, but it needs much more space than this.])
 (;B[f9]C[Black can also push the ladder one more then then climb.]

(;W[e7]C[Eric\:


This is better, since due to D6, is still connects.
