Interesting raise...very tempting to call

What do you guys think? I figured it's still early in the tourny. and sometimes people like to play 22 a lot and A2. so I'm thinking he has trips(which would be the only 2's left in the deck which is unlikely but possible) or also two pair Aces over dueces. So what do you guys think? Would you call this all-in?

he also could have 45 or a pair of clubs. I think if he had an ace, he bets flop, if he had 22, i would try to raise pot a bit so that its a heads up situation.

If he had 22 that would mean there were 5 2s in the deck

The only reason to fold that hand was if you thought he had 45. My guess on this one was that he had an ace or hit two pair at best. He couldn't have put you on trips, because there was no betting until the turn. Yeah, it was only level three, but that was a far too conservative play on your part. Even in the BB if you get a pair or any other solid starting hand, you have to raise to see where you stand. You get no information from calling & checking.

I would have either doubled up or gone broke on this hand.
