In these games, a lot of times your opponents will tell you that they have a draw and the rare times they miss on the river it gives you the opportunity to bluff profitably. At least I think so. Here are a couple of hands where I had jack shit, but fired on the river tonight pretty confidently that a fold was coming.

Hand 1
When he check calls this turn, I already know that I'm definitely betting any card that doesn't put a flush or straight on board. That river 2 might have been the BEST card in the deck (except when I make the nuts).

-------------------

Hand 2
Much smaller pot. He tells me he either has an OESD or a worse flush draw. As a bluff I'm betting ANY card that doesn't put a straight on the river. Basically, I'm only NOT betting a non-heart J,6, or 8 (8 would be a shitty spot though).
