BB bubble hand.

Table had tighten up due to being on the bubble my chip stack was about 16k, 20th out of 63, second or third at the table.

Blinds 800/1600

MP limps - about 12k in chips
SB limps - table chip leader
BB (hero) do the cards even matter here? Should I be making a raise here or just limp along and hope to catch something on the flop??

On the hand in question I had 72o.
I checked.
Flop is 237 rainbow.
SB checks, Hero??
