No1 folds 2p here, and some wont fold 1p since to a player at these stakes u rep AA blockbetting at best. So id only bet vs some1 that folds everything but like QQ+. Since ur bluff only needs to work 33% of the time its prob an ok bluff exxept vs a decent reg or aggro reg.

Seems like a lot of ur posts involve bluffing off a stack...perhaps its time to keep your image in mind before firing the last barrel next time?

Once you bet ott firing a blank river seems to be reasonable. But it does depend hugely on how villain is playing his draws and what he thinks of your value betting range in that spot.
However I'm not sure if betting otf is such a great idea, against someone who is raising a decent amount of flops it seems bad to be folding with an open ender and live cards.

I think the riverbet is to small because it gives villian 3-1 for his money and for that price he will never fold a made hand.
