Me vs. tricky LAG

iPoker 50NL, opponent is insanely tricky 55/5/2.5. He seems to be capable of floating, check-raising air, checking behind with the nuts, bluffing good, three-barrelling, the lot. He once stacked off with TPTK but often he shows down sets and TPGK played fast. He seems to be owning quite a few people apart from when he's got the worst hand vs. a 0th level thinker.

I'd seen him make this $1 donkbet before and I thought he was FoS.

if you see him play good stuff fast then he prob doesnt have a 9, so i would bet turn and bet river

Check behind on hand 1. You only have a PSB behind and you wont fold KJ+ against that villain, so wait when you have a real hand.

Hand 2, yes bet turn and river and win

hand 1 - I don't mind the bluff raise so much, but once he calls, give up.
2 is interesting, case could be made for leading or c/c or c/r turn. once he checks behind, I would bet river, although inducing a bluff isn't crazy either.

In general, against a tricky 55/5 I would bluff less (especially on wet boards, since he is going to show up with all sorts of crazy connectors) and value bet him to death.
