H1 probably okay after reading what you say. iunno bout river

H2 I'm confused why you are flatting pre and folding THIS flop??? this seems absolutely silly to me. dunno why u r only making it 9bb pre v someone you say are never folding to 3bs. you alrdy tightened up now make it like 12bb or more possibly

H3 reread what u said it doesn't make sense. anyway readless it's rly tough to say what he can have and I probably just muck. he can easily have like 66-88 and probably 65s for 2 more combos, this isn't a tonne of combos but probably all get played exactly like this. if he's checking back 98/j9 on the flop he obv has those too at this point. not really sure what air he'd have now that doesn't have showdown value and didn't decide to bet flop. I expect all overs to just bet the flop when checked to but Iunno how these games play now

H4 I'd check a hand like this back because of all the backdoors if he's really aggro then u'll have a lot of turns to peel with or you can raise like A/K turns just to see how he's going to react to this since you'll probably be checking back quite a bit if he's as aggro as you say.

as played I think raising doesn't look credible at all. you're probably rarely cbetting Ahigh if he's aggro like you say and if you're checking back quite a bit he'll know you are just super FOS when you pop this turn. this is why I like check back and raise A turns though cuz it looks a lot more credible. also your sizing is silly I think you should just jam your entire continuing range unless you can get him to spazz which you don't want him to do when you have Qhigh lols

just my 5c
