Flopped Straight on flushy board?

Good line? I'm still having problems with bet-sizing.

On the river, villain would be all in for $7.

Looks good. I think you can also raise more on the flop and then push any turn card.. if your opponents like to gamble with a flush draw or straight draw, or think this is a bluff-line and calls with TP/overpair this can work.

i would raise more on flop, probably closer to $3, try to get the pots really big when you have big hands

Gabe is right, betting more on the flop would be nice to increase the bet sizing for later streets. But your line is fine, personally I only bet what villian has got left on the river to make the river call seem easier for him (I dont know if it makes a difference though :))
