bluffing w/ outs, taking it too far?

[fire_fly]

I think this kind of hand is getting me into tons of trouble.

Flop, sb checks, so I assume he has nothing. Am I wrong in taking the odds here and betting out hoping they fold? It only has to work 1 out of 3 times to be profitable (and the draw will come in sometimes too.)

Is this a bad bet here? I'm guessing yes. Again, just taking the odds and hoping they fold...

, SB calls.

<font color="#CC3333">SB bets</font>, Hero calls

Does this call suck? I'm guessing yes. Man this was a terrible hand... But I'm bringing it up because I run into this type of hand alot at sh.

I'm curious to hear what everyone has to say.
