If he has the AA KK type hands - you will get him anyway.
disagreeeeeeeeee
the guy likes pot controlling and its not inconcievable that he checks back flop with AA cuz if he checks back its so much harder for him to lose his stack which is huge for him and he can now bluffcatch or get value on turn/river. in general it just makes playing the hand more comfortable for him if he checks flop, not to mention if our image is crazy he knows hes gonna be put in rly tough spots if he gets checkraised on flop and the worst that happens if he checks back is he has to call 2 streets which is much more appealing to him.
if he cbets and pleno calls and he has AA no spade and a brick spade rolls off on the turn, you think we're 'getting him anyway'? if any 9TJ7 or any spade rolls off on the turn we dont stack him imo. if pleno checkcalls flop and top pair pairs the board he prob just checks back even if it is better to bet just cuz he knows it sucks balls if pleno checkraises. and if any of the others roll off straight/flush/2pair possibilities just got way higher. and even if these spots are all better to bet/fold aces the last thing anyone wants to do is betfold aces vs someone checkjamming a turned draw but they dont wanna bet call aces drawing dead either.
in conclusion i think its REALLLLLY FRIKKIN HARD to stack aces in this spot vs a guy who hasnt shown much aggression and enjoys potcontrolling
tbh i think his most likely line with aces here is gonna be check back flop call turn call river...in which we dont stack him. he has to cbet for us to have any chance to stack him and i rly dont know if he does cbet that often
