$0.5/$1 No Limit Holdem
Both hands are against the same guy. Haven't been playing too long, he seems pretty decent. We've been talking in the chat and he says he plays a lot of HU. Seems to call 3bets very regularly and folds to continuation bets in single raised pots a lot.

Hand 1)
I guess getting it in here is super standard. 3bet the flop or call and get it in on a later street.
