5 handed in super deepstack stt, not played a hand for about 20 hands.

utg, not great 9 or 10 handed but 5 handed worth a raise and if nothing else, happy to take blinds.

But A4? How much do you need to raise to get the sb to lay down A rag? Maybe I should have re-raised on the flop but I'm thinking if I'm gonna win I need to turn good spots like this into chips and you don't get many better spots without flopping the nuts! If I re-raise on the flop, and he hasnt got an A he is folding and if he has an A he's gonna call whatever. Should I have folded after his bet on the turn? But if I fold spots like this then I may as well give up? Is the re-raise all in a terrible play?
Maybe its just me running cold at the moment. Oh and of course he won the tourney! lol
