Hero ???

villain was 19/16/2 over 400 hands. 3bet 5%.
My stats are almost the same.
No particular history between the 2 of us.
On the river there are only some hands he can have: sets (4 or 5 only), AK/Qx.
How much to bet on the river? $15? Should we c/f river?

Not sure what's up with your turn sizing when you wont alter his continuing range much if at all by betting like 11 at least.

No idea why w'ed ever c/f river just bet like 2/3rds and hope to get called by KQ QJs etc random Ax if he's floated the flop.

A2s/A3s peels flop. Just bet.

yea you wanna bet bigger on the turn so you can ship on the river. you probably need to pay more attention to stack: pot ratios

turn 10$, river now 23$

11 on turn as played i d flip a coin to decide between 17 and 21

^^ I like 21

Yup, you guys are right turn sizing is bad. Thanks!
