2 pair in the BB on the first hand of the Tournament

[juris]

Home game, 4 tables. First hand of the night.

I'm in the BB, starting with 2000 chips. Blinds 25-50. I'm dealt 7s-9h. 3 limpers come along, SB completes, I check.

Flop: 4d-7d-9d.

SB checks.

I should . . .

I bet about 3/4 of the pot, and I reraise any raise. If they flopped the flush, at least I have outs.
