CO has just sat down but he seems very fishy and is 86/14/1.3 over 7 hands. The first hand he raised was a click raise from UTG w/JJ

Button is the player from my 910s hand, a solid winning TAG

Hero (MP): $422.55
CO: $196.00
BTN: $405.10
SB: $129.85
BB: $202.00
UTG: $201.30

Pre Flop: ($3.00) Hero is MP with T Q
1 fold, Hero raises to $6, CO calls $6, BTN calls $6, 2 folds

Flop: ($21.00) T 9 J (3 players)
[color=red]Hero bets ?

I think in this spot c/c is okay.
However, I wouldn't c/c on 567 w/ 78. I'd cbet there since I c/f almost always with OCs there and only cbet overpairs. So I take not-so-strong, drawing hands to balance this very exploitable cbet behaviour. Also I sometimes like to cbet with backdoor draws on non-std cbet boards in HU spots..
