back to the QJ: a 4x raise seems too big, 0.8 seems fine as it gives him more room to 3ball

QQ - fine

KQ - weird line by the villian, sweet line on your part.

AA - This is fine as long as people 3b bluff rarely and call off a 4bet shove with enough weak hands. In general this will fold out a lot of his range tho and more importantly takes away his FE (from his pov) to 5bet shovel himself.

77 - This is okay. There will come a time, where u cant play it that hard on a flop this dry, where u cant rep a load, as long people stack off on TPGK+ its a cool line to take.

KK - I like, Im experimenting with smaller bets on dry boards as well. If you get caught doing this with strong hands, you can bluff here with smaller bets as well.
