Less than 20 hands on villian so no reads.

Ok so ignoring the fact that i should have 4-bet pre (yeah tricksy tricksy retard i am lol) can i ever fold this oin flop ? If we calling flop bet then we have to call a turn shove that is less than PSB.

Poker Stars $0.05/$0.10 No Limit Hold'em - 5 players

UTG: $10.30
CO: $14.65
Hero (BTN): $10.00
SB: $9.35
BB: $7.30

Pre Flop: ($0.15) Hero is BTN with A A
2 folds, Hero raises to $0.30, SB raises to $0.90, 1 fold, Hero calls $0.60

Flop: ($1.90) 6 K 3 (2 players)
SB checks, Hero bets $1.20, SB raises to $2.70, Hero?

EDIT : Also how do i get my signature to show the actuialy image instead of the link ?
