puny push and a supcisous caller, I have A9o 3.5 M effective stack

[pat3392]

I'm really have no clue if I made the correct play here. I decided to fold because of two reasons:
1) BTN call suggested he had a monster hand
2) If I called in order to hit my A and go all in with it then I'd miles push all in preflop, because if I thought my A on the flop was good that means I am most likely ahead preflop anyway and hence, should push it.

1) BTN call suggested he had a monster hand

this is more when ur a bit deeper and he flats it, calling a 1.5bb shuv isnt necesarily strong, this is KT+/A rag hand a lot. i would shuv bcos you have the best hand a lot of the time and he might even fold if hes terrible.
