KK overpair, river play?

[kickass]

how does it cost us money if he cant call when we bet bigger? it costs us money when he folds 77+ and when he raises us we've lost more. his range is small pairs looking to bluff catch Tx flush draws 6x sets/quads maybe JJ QQ.on this river only QT can call a bet if we bet half pot+ everything else folds or raises. unless he's a hopeless station which wasnt mentioned in the OP.

He'll call like $6 with all the hands we're vbetting against which is the majority of his range. 44/8 suggests hopeless station to me. Folding 5/7 cbets is consistent with fit or fold (where for station fit=pair). How is Tx from a 44/8 folding to $6 and calling $4?

Hence it costs us $2 when he has that part of his range we're vbetting, unless he folds Tx to $6 but calls $4. I'm not giving a 44/8 $2
