I've only played with villain (CO) the past two sessions. Has been aggressive preflop with 3/4bets but I haven't seen him do anything too aggressive/unusual postflop. I've folded to his preflop aggression and I don't think we've played any big pots together. On this table I've been straightforward after the flop

110bb effective stacks

2 folds
CO raises to 1.50
1 fold
Hero (SB) 3bets to 5.00 [Qs8s]
1 fold
CO calls 3.50

Flop:

Hero cbets 5.50
CO calls 5.50

Turn:

Hero: ?


There seem to be merits to c/c turn as well as b/f turn with the intention of c/f most rivers.

If I bet the turn and get called would you bluff a diamond/K/A river?
