Villain is not bad small stakes reg - 20/16/4 in 260 hands.
Only relevant preflop notes is he flat-called AJ BTN-CO with similar stacks pre-ante.
He never restealed bvb in 5 opportunities. His flop AF is very high but he never raised (or c/r-ed) cbets on a good sample, folding 80% to cbets.
Turn sample is small but he floated ott once.

I was active, no dynamics or history with villain in this tourney.

Hero...

I think his flop calling range is stronger than your average competent reg`s at this spot.
Seems like he has more KT,QT,Jx than KQ,QJ and he has more Jx than Kx.
Guess he also often checks back pair+decent_diamond card ott, so I`m kinda torn between b/f and c/c.

Thoughts on turn line and plans on rivers please.

b/f turn and chk/f most rivers since if he calls turn he prob has at least some sdv(maybe as weak as A hi but still) and if he bets i would imagine top pair med kick will be a solid loser.

I would keep up the aggression oop - he's got a lot of diamonds in his range to.

c/f turn

you really think he calls with dry A high ott? seems extremely ambitious.

pretty close to x/f myself, but prob choose to b/f to protect

Naked or pair+Ad is a call on turn IMO but that's a very small part of his range and if we removed it entirely I still like b/fold. I was just using it as an example that bottom of villains range has sdv

+1 (not including the Ah part)

900/f seems good now OP. Plan to x/f the ugly rivers.

Yea, still some value bvb.
B/f
