5/5NL
LJ= 500; crazy old white lady postflop; will shove entire stack when checked to with any draw
CO = 2k; 60's E European guy sitting on a massive stack; seems to play pretty tight pre but solid postflop
folds to LJ who opens to 15
H in HJ 3b 9
9
to 55
CO cold calls, LJ folds
Flop 8
6
4
(125)
H 80, CO calls
Turn K
(285)
V readies a big stack of chips to my left
H 145, CO calls
River 3x (560)
I check, CO snaps 500
I go deeeeep into the tank...
Is this a spot where, being OOP, I should bet small OTR to avoid getting bluffed by draws here?
