i prob 3bet or fold pre. as played you cant fold when you beat his overpairs, AKcc AQcc anything but 10x and 1010, 

assuming he is competent he will be raising super wide on the bubble with the chip lead, equally he will be barreling pretty wide if people are laying down hands like yours.

you should put down stack and pot sizes so its easier to get a feel for the dynamics at the table.

i dont like jamming flop because you fold out his weaker hands that will barrel turn, i prefer letting him barrel it in and keep his range wide. raising turn is prob better because he is priced in to call with alot of his A high hands. only advantage to raising flop is you may fold out like 55-77 which currently crushing us, but 88+ and J10 Axcc 109 are all calling regardless so we may aswell not narrow his range. on turn we are basically crushing everything but a tiny few combos of his range so snap him off, the 4 is actually a good card for him to bet for value with any pair and prob bets his A high expecting to get us off a split, plus it lowers the combos of hands that connected with that flop that we flat pre and flat flop to basically A4s/J10s/109s which is a super narrow nut range. so we have alot more floats just to float in comparison to value hands.

i'm 3bet shoving here against this villain's perceived range ; the old guy is probably folding(obv. unless you've seen him flat/trap with big hands before-dolts are gonna dolt)…are you the BB in this hand?  You are not deep enough to be flatting here vs. guy who will prob cbet 100% of range here and knows you are missing most flops anyway(if you are focused on ICM you should be folding pre and not hoping to connect with flop).  Fold or ship pre, imo. 

3b pre or fold.  Never folding once we make our hand, just not deep enough too.  If there is an ICM mistake it's in calling pre instead of playing a 3b / reshove game with that stack.
