Re: 20/40 high: Marginal
 

I like the raise on 3rd st with the live hearts & high cards. 4th:If you still consider the hand good enough to call now in this small pot after bricking, it must have been good enough to raise 3rd. Personally, I would fold with this small pot but would have called if I had raised 3rd. 4th:Don't like the c/r against the 3-straight in this small pot. Betting out is plenty, imo. 6th:He thinks you have a better hand than you do, & he still raises. You're dead. Fold. 7th:Fold.

I think that villain doesn't have the straight or trips on 5th, or he would reraise there.

On 6th he is claiming to have the straight - he may have nothing at all, especially given the two threes that are already out. Personally, I would check/call 6th, and then call 7th, given that hero has made two pair, and villain most likely needs the case 3 for his straight. I don't see any real advantage to raising here.

You're right, guys. He put the play on me on 6th, & I fell for it like the fish that I am. I was a dumb shat to fold. Thanks.
