Theme of my life - what to do with the 2nd nuts.

Villain is Mr. Mole, 28/20/9.1. What I think is relevant is that in the chat before this hand we had been discussing how bad I have been doing - I had lost like 2 coolers and then two flips in the 20 mins before this hand all 200 bb deep at this table so I was stuck a ton on the session - . I really think them knowing that will change how they play versus me and bluff me less since they think I'm tilting. I think shoving here would be bad...calling is close and folding is probably best. It's pretty simple...he's just never bluffing and these guys probably only c/called 66 on the river since my river value betting range is actually pretty polarized so no need to raise it since I'm never b/calling AK and probably checking KJ.
