it was about the fifteenth hand on the final table ,just the hand before mp+1 doubled and now i'm second shortstack on the table .MP is good reg on the tighter side i would say ,and it seems very good spot for him to be openning quite wide in this spot since every player in position has smaller stack ,and he was playing tight this final table so far so i would put him on the range of hands like QJo+KTo+A8o+T9s+JTs+QTs+K9s+A5s A8s+

So i have 9c7c seems standart defend from BB against the range i'm thinking he has here.

So he c-bets 71k to 200k pot and now it's 271k and i have 503k behind . So i decided to jam since on the small sample i will not lie (about 80 hands) but all this hands were on the semi final table about 45mins ago he had 100% cbet flop and against his preflop range with 100% cbets i'm doing very well on this board with my hand.And i'm definitely think that he would be barelling on any big card wich is very bad for me obviously.
But i wonder if it would be better to just call on the flop and call turn pretty much all the time since after we calling he's giving up some rivers with bluffs and taking some weak showdowns with Ax high because of paired board and i'm still having a lot sixes in my range and still can call down with my nine on some runouts .
