Complete third. I can't see any justification for limping, either to reraise or not. Bet 4th, and don't be too upset if you are raised by either the player with TK or the 3A guy. It may be what you need to narrow the field, and with the money in the pot, you can go to the river.

If you decide to check/call 4th, why bet out fifth? Sixth and seventh are fine.
