1 you cant call with that hand every time preflop. its better if villain can think you can call a 3b with strong hands like AK/AA. i would rather c/c on J53 more than K53 because they are more likely to barrel you on K53 when you have the best hand
2 hate the flop sizing. i like checking QT and betting bigger w KQ
3 i would bluff turn with worst stuff (67, 79, q9dd) and then follow through on river with those hands. with QJs i like checking and raising river when you hit and probably on an 8
