Do i put my chip leader stack at risk?

[bsiu5]

ok, first thing is first this is not a bad beat story so if your gonna make a comment like that then don't comment. my ?, has nothing to do with the way i played cause i would have not done the same if it was a SnG game but this is a tournament.

button with Q10o. EP(weak tight-shortstacked, like to raise and see the flop), raises 3xBB. right now i'm the chip leader, 2nd chip leader is to the left of me on the small blind (diff. in chips is about 1000, BBs are at 500 right now). i decide to min. raise hoping the blinds will fold and i can go heads up. usually i wouldn't raise but i was mixing it up this hand to add deception. to my surprise SB, 2nd chip leader, calls as does EP.

Flop is AKJ all clubs. great got the straight on the flop, all checked to me. i bet 25% of my stack which would have put EP all-in, as soon as i put my chips in the SB 2nd c. leader goes all-in. EP folds back to me. This is what i'm thinking since i've played with him for a very long time. i know he didn't have the flush because he would have slowplayed no matter what 2 clubs he had so i put him on a set or 2 pair.

here's my ? i know i'm winning right now but he may be on a flush draw with one of his cards being a club or he could hit his outs and make a boat. in an SnG game i'd instantly call but in a tournament you can't rebuy. Right now, 25% of my stack is an all-in for the rest of the 8 players on the table except the 2nd chip leader. if i lose this hand i'm basically all-in the next hand. if i win, i pretty much win the tournament. I tell him, "i got the straight but i'm not sure if i want to let you double up and outdraw me. i flip over my cards and told him, i'm laying this down cause your goonna outdraw me. everybody on the table was pissed and told me i was an idiot for folding. I told him i'll beat you when i know luck ain't gonna save you. sure enought he had AJ for 2 pair. everybody on the table, wanted to rabbit hunt and sure enough a Jack came on the river and would have made his boat.

i ended up winninig the tournament when he had a boat to my 4 of a kind.

But i really want to know cause i think at one point in a tournament i'm put to a decision and know that i have the best hand but i dont' want to get taken out by a lucky turn or river and have to watch from the sidelines, was that the right play in folding this hand? Granted i made the right decision at the time, but is it better to call his all-in when i know that one hand could decide my fate in the tournament?

please, i would like to here your opinions.
