I like the flop bet, particularly since a card that makes your hand is unlikely to improve his so much that he'd want to call your value bet later in a tiny pot. I don't like the second barrel though - the main problem is that it's sized just so he'll call it all day with anything reasonable, as well as some draws and some completely unreasonable crap. I like a check here, but if he's the kind to pounce on a check, make a better-priced bet there. I'd prefer to see you bet $1.00 or .40 instead. .40 is probably better EV-wise since it's about the price you'd want for your draw, and you only have to get paid a little more to profit when you hit. 1.00 or so is the only reasonable second barrel bluff amount. .60 is the sweet spot of suck - it's a bad price for your draw and he probably seldom folds to it.
