I've not played much for ages, and have always been pretty crap, but I actually felt quite comfortable at this point.
On Mansion. a $2 MTT re buy. During the re buy I was lively, but since the break I've been tight - played only one hand. I was on the button with




10 seater table
I'm in seat 5 for this hand.
Blinds 800/1600 with 160 ante.
SB is playing well and has a big stack
BB is loose and has a similar stack to me
Player to my left has been playing well, but has recently taken a hit
Player in CO is probably the best player on the table.
Both have me covered.
I have 19,000 chips.
I get dealt


It's passed to me, I raise to 4,800
It folds round to the BB who flat calls.
Flop



BB instapushes.
I'd have put him down for a preflop push with an Ace, or a pair. So either he's hit his mid pair or he's playing a stop and go on me. Because of the speed of the push, I have it down as a premeditated move and suspect the latter, so after taking the clock down I call.
Poor thinking? What do you reckon? I know you guys think on several levels more than me, so , if possible, can I get a view of the proper way to think about this, but also maybe a may I could think about it, given my lower skill set ATM. IE should I just make a standard push or fold preflop, until my thinking gets better. Or maybe always fold postflop in similar circumstances?
Cheers
