;W[d4]C[Peter\: Now Black connects in the a1 corner area.

d3 would have ensured that White at least gets a 2nd row ladder, which would have probably been good for White (although White still had a weakness in the k1 corner).]

;W[d8]C[Eric\:

b5 and b6 are equivalent here, and they reverse c3 (similarly to https\://www.hexwiki.net/index.php/Peep#Automatic_peep).

So White should've played one of them, to guarantee a ladder escape.]
