Should I just be betting myself?

SB posts SB 0.4 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.4 BB) Hero has T♠ K♠

Hero raises to 2.8 BB, fold, CO calls 2.8 BB, fold, fold, fold

Flop: (7 BB, 2 players) T♦ 7♠ Q♥
Hero checks, CO bets 3.32 BB, Hero calls 3.32 BB

Turn: (13.64 BB, 2 players) Q♣
Hero checks, CO bets 6.48 BB, Hero calls 6.48 BB

River: (26.6 BB, 2 players) J♦

I mean the J is one of the worst river cards imo - he is a 38/8 and played a set like this

I usually check/call a lot of middle pairs and weak top pairs.

The AK hand I kinda like playing a strong top pair like this sometimes - because it gets them to bluff
