Hello,
Why do we minraise preflop? I think it's an easy 3bb raise here.
On the flop I'd bet around $0.2.
I think we can bet the turn as well here.
We are likely to get called by 7x/99-88 and also could make him fold some ace high king high floats.
On the river I think your sizing is good.
Best,
Plamen
