pre is w/e, just gotta make sure you know what range youre actually 3b in this spot (ie if you had 47s, 58s would you have 3b)- this is more of a bookkeeping question. suited one gappers i think are fine here to get some coverage on lower boards against a good player/hand reader who is gonna peel light, and who you want to 3b a wide value range against (bc he is opening so wide).

flop float again is okay, but only if you think he is going to donk/barrel with a lot of his air (which he has a ton of) which he will c/f later. i think a flop raise okay too, he will probably only continue with 5x for the most part and gutters are decent air to include in a flop raise range if you are gonna raise some overpairs (TT-KK)

calling this small turn bet is standard, raise here would be horrible. The Ah is good for your range if you peel with most of your AQ/AK (as you probably should, although maybe calling with more pairs on the flop is better if you do this), but it doesnt really make sense to raise any of these hands here and described villain will know this

river fold is pretty bad, agree he can be valuebetting worse. i would almost be relieved that he overbet bc then i dont have to consider raising a normal sized bet which would be super thin (probably too thin, hard for him to have much of a calling range that we beat). if youre gonna fold this river then fold the turn

someone above you said clicking it back to 380 or 400, thats more my style, because hes smart enough to know im going to bomb any river.

i guess i forgot to mention a key element in the situation.
i basically took 900 off him an hour before. I didnt feel inclined to give him action, It was my ego trying to outplay him in ALOT of the pots that we were playing.

like i said earlier but wouldnt clicking back the turn to say 400 make him play is hand face-up..

amen to that. I feel like ive gotten some pretty good advice though.
my next hand that i post will not contain the results until after discussion is over.
