Did I just get lucky on the river here, or did I play this right given my reads?

I think you got lucky, and you played it fine. Against a LAG I think that's the right amount of aggressiveness. Only after the turn raise does it seem like he's got the best hand (unless he's extrememly LAGgy), nothing for you to do but call and get lucky on the river /images/graemlins/smile.gif
