Dacha Tactics #72 - Carlsen hiccup!! dark pawn dacha.

I saw this game in a Titled Tuesday tournament, Carlsen is black vs a strong NM. Carlsen misses the correct plan and only draws! This may be a pawn endgame but make no mistake – colors come in prominently in the planning. Find the win! Hint – dark seems to be a key color. Ke5 would be juicy and winning....the b6 push seems to be important too, both for white and for black as it will decide just who is in zugzwang...
