Fold preflop. You'll be drawing to a one-way hand against a player who will bet the button at every opportunity.

I don't mind this postflop. If Button's range is random, and he is loose enough to still hold many one-way draws after calling the turn, the river bet is fine value-wise. It will be rare for Button to scoop, even if he did so here.

You might want to consider check-calling or check-raising in spots where you have a good two-way hand that might induce a river bluff (followed by a weak call) from an aggressive player's weak hand.
