Anybody struggle to win in live games while beating online easily?

BTW, a small note. I've only had 4 sessions of IRL play, total of 20-25 hours, 3 2/4 sessions and today was my first 4/8 session. Although in that timeframe I'm down like a lot, $500ish :/ Some of those sessions were back before I was even playing seriously however (2 of them were before even reading 2p2 and realizing what a TAG was etc).

Back to the hand.
The TAG had limped behind others and decided to slowplay a set of 9s.

It was national slowplay day at my table (I'm not sure anybody who flopped 2-pair or better bet/raised the flop the entire session). I obviously didn't put him on the set of 9s, my big problem with calling/re-raising the river is that people at this table just weren't bluffing, or so I've seen. I figured he had to at least have a K he slowplayed and I was worried about my kicker at that point.
