Villain seems semiloose pretty aggro. 33/20/3 (AF). The turn is a missed check/raise since I figure floats are a pretty big part of his range and I dont hate giving a free card. The river confuses me. The flush is obviously much less likely since I hold the A. So it seems hes just repping a FH/Quads. Whatever hes repping it beats me, but its a pretty thin range and my hand is underrepped. Whats my action?
