This hand is from the first $550 Deepstack event (Brag:which I FT'd, Beat: agreed to a 9-way chop, Variance: got a decent deal), and it's been bothering me because it's seemingly simple, but I'm not sure what is the best line vs. an unknown.

This is the 2nd hand of the tourney, everyone still got their 10k starting stacks, blinds 25/50.

I open to 150 in MP w/ KQo. In his 30's guy calls behind me, BB calls.

Flop (pot:475) KQJr

BB checks, I bet 300, 30's guy min-raises to 600, BB folds, I?

Do I 3bet-call a shove? 3bet-fold? 3-bet to set up a turn shove? Call and c/r blank turn? Call and c/c blank turn? Call and lead blank turn?

Call and c/c blank turns.
