This is sorta a hypothetical, but what is the worst hand you call with on the flop facing this weird stop n go line?

2/4
$400 stacks

SB is 24/18, seems pretty good and aggressive pre flop.
so far this session he's folded a lot to late position raises, so maybe a higher chance he 3bet light.

Hero is 22/19, and very aggressive pre flop, usually 4betting AQ+/JJ+ but sometimes like T9s/Axs.

Pre Flop:
3 folds, Hero (BTN) rasies to $14, SB reraises to $48, BB folds, Hero 4bets to $150, SB calls

Flop: K 9 4

SB gos all in for $250. Hero...
