Big decisions in level 1

I had this one in the Open tonight. The villain is completely overplaying his hand, but his line just didn't make sense to me, so I thought I was ahead. Even so, would you call here?

jdnorway calls $640 <------- Reraising all in here accomplishes nothing imo. I get rid of hands I'm dominating, but the only two hands I really fear (22 and 33) will call.
Dealing Turn <------ You always hate seeing an ace with KK, but I can't really put him on AQ after the limp pre or A2 or A3 after the reraise on the flop.

Hak215 bets $1,730 (all-in)
jdnorway has requested more time
jdnorway: 22? 33? 45?
jdnorway is using the time bank
jdnorway has 65 seconds remaining in the time bank

I would prefer a reraise on the flop, in the open you will often see calls with a fair few hands you have crushed, KQ, QJ maybe mid pairs too.

I am more inclined to call here as played my gut says something like 9s and he sees the A as a scare card and shoves....hard to know in level 1 of the open, but its worth a risk here IMO to try and get a stack.

Big decision for sure, but what kinda tournament was this? SnG? Buy-in?

Just for completeness, I was right, but it didn't matter:

I hate to have such a big decision to make early on, but if he had raised to 80 preflop, I would've been much more likely to believe he had AQ - but of course then I also would've shoved the flop, so it wouldn't have changed much.

Your play was correct, just unlucky really. And I can see why he raised you, he had a top pair and for many (poor ) players a top pair is a way to go. It's hard to lay down KK in this situation.
