8 players post ante of 0.13 BB, SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 2.5 BB) Hero has K♠ A♦

fold, fold, fold, fold, Hero raises to 2 BB I felt stuck here and didn't know if I should just jam 16bb, fold, fold, BB calls 1 BB

Flop: (5.5 BB, 2 players) J♥ Q♥ 7♦
BB checks, Hero bets 3.5 BB, BB calls 3.5 BB
I know BAD BAD BAD flop bet when the board hits his range and I could check behind with my GSD

Turn: (12.5 BB, 2 players) 8♠
BB checks, Hero checks

River: (12.5 BB, 2 players) 5♦
BB bets 7 BB, Hero???

So how do you play this preflop?
