$Freeroll NLHE MTT: Should i have pushed all in after the flop?

Below is the hand history as supplied by poker stars. I am aware that with my hole cards i was a 5% favourite, and right after the flop i was 75% favourite to win, after the turn i was still 70% ahead, that was when i raised , I wonder if i should have pushed all in? after the flop, i did not know the players styles as i was just moved from different table. Thus i tried to play cautiously .PokerStars Hand #184522614218: Tournament #2235055039, Freeroll Hold'em No Limit - Level III (40/80) - 2018/03/29 15:16:30 CUST [2018/03/29 9:16:30 ET]

AT o from OOP can cause a lot of post flop problems. Here I would advocate a pre flop 3 bet of 8-10 BB or a fold, with my preference being a fold.

Once you get to the flop, the initial pre flop raiser checks. I do not think that they would give up the betting lead with a strong hand. Flop check raise all in might be the best play, but you would have to go all in and still have to worry about AK, AQ, AJ, A4 suited, JJ and 44. AK and JJ are less likely, as most people will 3 bet those hands pre flop.

Long term, fold AT o OOP pre flop this early in the tournament
