BB: $300 eff, stationy preflop, tight postflop
HJ: $1500 eff, LAG preflop (opens way too much, like 65%), tightens up hard postflop, capable of folding/not paying postflop

I cover in CO. My image tight/solid. HJ opens to $25, I 3b to $100 with J♦ J♥ BB and HJ call.

Flop: Q♣ T♣ 9♠ Pot $302 Checks to me

What should we do and what's our plan for the hand?
