55 BB vs steal

[MrEngenic]

party 10/20
29/21/2 lag/tag, wtsd 36, steals from button. He plays good and is a bit unpredictable and a good hand reader.

I 3bet 55 from BB, he caps.

Flop 236r
I check, he bets, I cr, he 3bets

Turn A 7BB
I check/call

River 7
I check/fold

I would call river if turn was anything but an A. Do I donk or cr river if I improve?

looks good

go for the c/r

you could easily have something like 99 here
