more blindfold (can you draw?)

remember this is to be solved blindfolded, so please do not post diagram.
from susans wonderful blog, black to move, can you draw?

black: b7, Kc7 white: b5, a5, Kc5

1. ...b6 2. axb6+ Kb8 or 2. a6 Kb8

Dunno if I'm right heh.

1...b6+ 2.axb6+ Kb7 with taking pawn on b6 in next move which leads to draw.

If 2.Kb5 then 2...bxa5+ 3.Kxb5 Kb7 with draw.

Ok yeah I didn't see the check. Having a board would have helped with that. 🙂
