Or they're about to double up, putting you about even and wishing for a hand as good as 77 to push with.

IMO, folding up to JJ is weak thinking unless the chip leader is a verified rock. There are a lot of hands that a good player would use to challenge a completed SB or minraise.

The case for pushing into the BB (prior to the reraise):
The BB has a random hand, and 77 will dominate about 70% of all possible hands (any pair less than 7 or any two non-paired hole cards where at least one card is 7 or lower). About one fourth of the hands (about 16% of all hands) that 77 dominates will be two cards behind.

77 will be a slight favorite (say 53:47) to fair percentage (27%) of hands (two overcards). Consider that AKs is behind 77 preflop (48:52).

Only 3.4% of all possible hands will dominate 77.

That said, 77 is a vulnerable hand that could use folding equity, and it is difficult to play post flop unless it completes a set. By raising all-in preflop, you get folding equity and avoid having to play it when it misses. Although in general situations (ring game, early in a tourney) you would prefer not to push all in since you won't get called unless you are significantly behind or only slightly ahead, it is reasonable to expect calls from hands you are significantly ahead of in this situation. Getting a fold and T$300 would be a great result, too.

Bottom line, when you're playing 4 handed with only 6xBB, 77 is a great hand.
