I'm in a unfamiliar casino , no familiar faces. My desired 50p/£1 table is full but there is a seat on the £1/£2 table which i sit down at , buying in for £160.1 guy has approx £500 4 guys £200+ 2 guys just over £100.
After 20 mins it goes.
Seat 3 raise to £16
seat 4 call
me in seat 7 re raise to £50 with

, i do this to prevent any other flat callers and to get it heads up.
All fold to seat 3 who flat calls
seat 4 passes.
Flop is

seat 3 bets £70 ,action on me.
Seat 3 in the 20 minutes ive been sat has been involved in all pots bar one.He's also the guy with £500+.
In all honesty i didn't have a clue what he had in his hand but i decide to shove what i had left which was £94.
He duly calls the extra £24.
Cards come

Expecting him to table Ace picture or ace something , my kings took the pot , he showed pocket 9's saying he hoped i would pass on the flop.
I think my pre flop play was Ok but what about my post flop play? I was fortunate he didn't have the ace this particular time .
Given that i had put a third of my money in preflop is the shove of £94 with an ace there Ok as an all in preflop would have yielded the same result.
If i did decide a fold , would that be ok too?
