Whenever someone is showing a lot of strength, you should feel better about raising your strong hands harder/bigger than you normally would, without being worried about losing their action.

The other hand was because he was betting into a big field, and this hand is his turn bet sizing. He's betting pot which makes me feel like he's not going anywhere. I'd probably raise to around 21-22ish.

ul though, but you'll punish the fish in the long run!
