   ;B[h4]C[Peter\: This is similar to what happened when Black played h3 instead of h2, but the important difference is that now Black only gets a 2nd row ladder escape, and not a 3rd row escape as in the actual game.

In general in this situation, there is an even better move, called "Eric's move"\: j4 instead of h4. See https\://www.hexwiki.net/index.php/Climbing#3rd_row_ladder. But I'm not sure if it works here, due to g7.]
