There are a couple of things going on in this hand.

First the pot is large and that's key. Second we know that a call is right, and a fold is wrong. THe question is will a raise be better?

We can raise for several reasons:
1) Get more money in the pot (not likely what we want here)
2) Knock other people out
3) Get a free card on the next betting round
4) bluff(we aren't going to bluff in large 5 handed pots)

I believe what Ed is getting at is raising here will knock other people out, and possibly get this pot to heads up.

Why is that good?

Well let's say you have an 15% chance of winning and the original better has a 40% chance with 5 players. Your raise to heads up makes you closer to a 30% favorite and him a 70% favorite. Your expectation from what you will get out of the pot is now higher than the extra bet you put in. In otherwords you benefit even though you like don't have the best hand.

Now my percentages are really rough, but we could deal out real world hands and show were this situation comes up quite a bit, though it does happen a little more often in stud.
