I'm not the villain in the hand and i've crossed out the name of the villain in question as i'm sure he'd like to remain anon. I was just on his table and was interested to see a check-back with top set here

Struggling to find many hands besides AK/KK/JJ that he'd play this way? Certainly not enough club combos for us to be checking back this river imo.
