Call or fold to this all-in bet on the flop?

[Buddy Love5]

Earlier in the tournament this same situation happened between MattyButts and another player. MattyButts calls the PF raise and then goes all-in on the flop. It was then folded to him/her.

I felt like I was holding the best hand since I have seen this before, and assumed it was a bluff.

I was just wondering what ya'll would do in this situation.

standard play is to fold, no one has your read but you. if he has a pair you're about a 3/1 dog, worse if he has something like AT. You are getting a decent price but still you need to be pretty sure you're ahead.

What I don't get is how you know he was bluffing the first time.

The fact that he has called half his stack pre-flop smells like a big hand to me.

You could be completely crippled and dominated here, so easy fold for me.

I wouldn't rely on the bluff read you have there either. He could have held a monster there too, in which case he's making a risky but somewhat profitable play if his opponent misses the flop or catches tp.

I never said I thought or knew he/she was bluffing the first time. If I did say something like that I didn't mean it. I have no idea what he/she had earlier when he/she did the same thing earlier in the tournament. All I was saying that I felt like it was a bluff on the hand I was against.

In that case fold. It's probably a fold at other buyins too. You may be folding the best hand but IMO it's not worth the chips that it will take to find out.
