BB is a solid 3-bet heavy low-stakes reg

Preflop (60) Hero is BN with K Q

3 folds, MP+1 raises to 120, 2 folds, Hero calls 120, SB folds, BB raises to 440, MP+1 folds, Hero calls 320

Flop (1,020) T Q A

BB bets 500, Hero calls 500

Turn (2,020) T Q A A

BB bets 1,000, Hero calls 1,000

River (4,020) T Q A A 7

BB bets 2,820 and is all in, Hero calls

combos that beat me:
AQ (4), AA (1), QQ (1), ATs (2) = 8 combos

combos that I beat:
AK (4), KJs (3), AJs (2) + bluffs (?) = 9 combos

Very close decision. What's your view?
Thanks, very much appreciated
