i think the key problem here is that you go for a check raise instead of a normal cb.
when you check raise, your hand is basically a bluf. you hoping that he has hand like AT or 66 and just calls. so you can hope for a 2 ott.
i am not a fan of a check call either. I think when you, after raising pre flop to 8,bb, check call you are exactly telling him that you have an overpair and want to potcontrol.
so i would just take the normal line and cb otf. especially live tournaments, people most of the time play very honestly.
just cb flop and take it from there, imo
