Preflop
I kind of want to 3-bet here to thin the field. But its sort of awkward, because you would need to go very large, and if someone call, now you are playing a massive pot out of position with AJ. Or if the original raiser 4-bet, you have to fold, unless you know something about him. So I guess, its ok to stick in a call and see a cheap flop. But I am not excited about playing AJo 4-5 ways out of position, so I could even see myself making a tight fold here.
Flop
I would not chase after just a gutshot in this multiway pot. If you hit an A or J instead, you have no idea, if its good, and you might end up losing a lot of chips.
Turn
It seems like, you are mentally playing all your
hands backwards and making up your mind about the correct action depending on, which cards come later. But this is not, how poker works. If you would be ok with your fold, if the turn had been 2s, then you should also be ok with it, when turn is Qs. Poker is all about math and probabilities, and the chance of nailing a gutshot on the turn is only 8,5%.
