Pocket jacks in early position

[sirtemple]

I've been troubleshooting some possible leaks in my game, and I came up with the following hypothetical.

Blinds 100/200 you have 5000

You get pocket jacks in early position and raise a it to standard 800. Folds to a late position player who re-rasises to 2000. He has 10000 more. It folds back to you. What do you do?

Ignoring obvious reads - what do you do?

I would go all-in in this spot most of the time, but I think I might be misplaying it.

Any thoughts?
