Short stack calling 2 all-ins with TT?

$65 Paris 9:30am tournament and we're down to 6 players. Top 3 get paid and the blinds are at T400, going to T800 in 5 minutes. Short-stacked 2nd position goes all-in for T2000. Small blind has about T10-12K and calls the all-in. In the big blind, I have 2400 and have pocket tens. There is one other big stack, a medium stack of about T4-6K, and one short stack less than T2000. What to do, all-in or fold, with these generic facts? I'll have some an orbit before getting hit with the 800 blind, but I need a spot to shove soon.

My read on the first all-in was that he had small pocket pairs. He had called with big hands earlier and made a small raise with AK. He did not look like he wanted a call and was somewhat deflated when the small blind called.

Small blind was a good player. No solid read but I felt his range here was pretty wide. I was thinking almost any suited Ax or 2 face cards on up. If I trust my reads, what's the play? Is my range on the small blind too big or small?

I personally would go allin with this without even thinking. Tens are a big hand 6 handed and you only have 6BB soon to be 2-3BB after the blind increase. If you trust your reads you would have to dodge 8 cards out of the deck (the short stacks small pp for the set: 2 cards, the other guys overs: 6 cards at the most). Of course you could be way behind but at this point with that little of chips and only 6 handed that is a risk I'm willing to take. Even if your reads are bad I would still be shoving my chips in the middle because I doubt you're going to find a better postition than this. You could be in better position than you think also with both players have in Ax or both smaller pp's.

Thanks for the response.

It didn't feel like a no-brainer at the time, but getting 2-1 on my money and really only hating bigger pocket pairs, I was all-in. Friends were split over the right play since I was so close to the money. Other short stack had 8s, which I loved, but the small blind rolled over AA for the third time in the tournament.
