$23+2 poker.com - how do you play this?

[BDPOD]

Sorry - I can't find a hand history convertor for poker.com so I will go from memory.
1-20 paid (11-20 get $30 then the payouts start to escalate at the final table.)

120 players to start.
11 players remain with 6 at my table.

I am average stack with 14,000
Blinds are 750/1,500 with a 50 ante.

I'm UTG with Ah Kh and raise to 4,500.

All fold to BB who calls.

BB seems to be TAG but not really noticed him doing much and has about 12,000 when the hand started.

I have been playing tight at this table - only played 2-3 of the last 20-25 hands

Flop is 10 2 4 rainbow.

What now?
