Reggish table

BU good aggro-reg vs who I've history.
A little sticky/catching

Preflop

Not an auto-3bet oop, but my hand is a good hand

3bet doesn't seems me awful, but calling oop with a hand with playabilty ok but not awesome, A suited, good pair (not that big) and make some nut straights seems me ok

Flop

Trips good kicker.

cbet it obv, for value, for protection vs FD, vs Axxx low kicked, for the times I'm not having Axxx but rep it etc...

Not sure about the sizing.
paired locked board when I'm repping strong, I put a ~55% size bet, but maybe too heavy, I could have bet lighter (7-8bb)

When BU calls, he's not that heavy as ip, and vs me in a board I'm cbetting very often, he will try often to catch etc...
Good flush draws, intermediate pairs catching (especially if he gets FD with), all is Axxx obv

Turn

not the best turn of course.
I'm dead (and oop) vs AKxx
He could have some KKxx that bink this turn

But I've still value/protection vs FD (which he would fold often here now), midpair (same, even if he doesn't have much because with my QJJx I'm blocking lot of them. Stay KKxx that is full now)

River

SPR ~0.5
not the scariest river

I'm giving my money vs AKxx
I'm valuing / giving him some headache vs undertrips (even if here, with my AQJJ, I'm blocking lots of trips with big kickers)
I may hope he fold / giving an headache vs A5xx. Not this 5 is the most terrible river. But as he's aggro preflop and he's opraising almost all his Axxx and not fold very much oop vs 3bet, if he has Axxx he would have any cards with it

check/decide doesn't seem me a good option.

check/calling, I think I don't have much value (bluff catch) with check/calling as if he's catching to here with some middle pair, he's not bluffing now.
And he wouldn't bluff with draws (who are very rare here I think).

check/folding seems me not possible with that SPR and that hand

so bet for value lower Axxx
