This all depends on what MP2 have. Since he was pushing all in he may not need a very strong hand. But he probably has at least two pair.

Alternative holdings:
1. The straight. We have three outs to a split. Disaster.
2. KQ,KJ: 3 outs (= 1 out + 4 outs to split). Bad.
3. A king + flush draw - four outs. We barely have the pot odds.
4. Only K (not Q/J kicker), K two pair, or a set < KK. All six outs are live and we have some overlay. Nice.
5. T9 (or worse) two pair. We have 12 outs against MP2. Very good.
6. MP2 is actually just on a draw and we are ahead at the moment. Improbable but would of course be wonderful.

If this was HU I would call, but this all assumes that UTG will either fold or just call and not have a hand that interferes with any of our outs. That is assuming a lot.

What do we think UTG has? A king seems probable, and a hand like KJ or KQ is very possible, in which case we are in bad shape. I think a reraise is better than a call. This assumes UTG will fold a king for a raise here or fold on the river to a continuation bluff into the side pot (which I think is a reasonable play against most opponents).

The reraise might be the right play if we had a read that MP2 was a maniac, so that there is a fair probability we are ahead.

My opinion (unknown opponents): fold > raise > call
