Hrewsahgs:
In the D2 descent variant after defender plays D4, what if the attacker plays B6 instead of C6?

This problem had just one (incomplete) correct sequence and it was all. I added 2 alternative sequence (one from the next problem, and one invented on place (the white nobi to the side). Also added couble of white refutations. If someone strong can check my moves and refutations, it would be appriciated.
