Nit is basically a shark bro. What you are suppose to do is play intelligent maniac. Meaning raise 2.5x 30% of
hands preferably from late position and c bet 75% of flops at minimum. Of course this is just generally speaking. play small pocket pairs from any position, 24s,53s,56s,64s,74s,63s,76s,8Ts,JTs AKo,AKs,AQs,AA,KK,QQ,JJ any pair lower for sets, avoid suited aces and careful with AQo or lower.

C. Making them looser preferably in the 9 to Q range and then cracking them with your hand.
D. Winning run outs with effective flips.
E. If its a cash game just table switch since it is a NLH grotesque plateau table.
