Whats the right play?

I will say that villian has not been very active in the time I've been at this table.

If I call and win, I'm chip leader. If I call and lose, I'm in the middle of the pack and a little below average.

My thoughts: Why is he pushing here instead of making a standard raise? He clearly doesn't want to see a flop or he's representing a steal with crap.

Now Button shouldn't be desperate IMO (m=7.2). He's not in horrible shape given the blinds and not in need of pushing weak out of desperation. but surely he wants to accumulate some more chips.

So which is right? folding and not risking 1/2 my stack? OR calling and trying to move into 1st when chip stacks matter most?

Please give detailed thoughts on your action. Enough of these "call" or "fold" posts with no explanation please.

I have a very strong opinion on this which I will keep to myself for now.
