Preflop: Fine in a 2/3 blind structure

Flop: Since opponent is capable of betting a draw in the circumstance and a checkraise won't lose anybody, a call is fine.

Turn: I guess betting here is reasonable, since you probably will go to showdown anyway, betting is better than calling.

River: Since he probably doesn't raise unless you're beat, the gating factor on check/bet is how often he bets a busted draw vs how often he checks behind with a hand he'd call a bet with.

edited to add: I bet the river. Checking after betting the turn looks suspicious. I think you miss a bet way too often by checking here.
