Opponent is a total nit at 10.x/4.x/2.xx after many many hands. Usually when I get tricky I have position but I think this is the only way I get his stack if he has a lower pair than me or hits the flop good enough to give me his stack. Only the 6th time I haven't reraised it in over 166k hands of full ring. I think running bad atm may be clouding my judgement . Comments welcome on the huge overbet as well but I was trying to rep a draw.
