calling a raise to go all in with KT with small stack is it right?

[recondite7]

My thoughts were that I was behind, but the blinds and antes add up to 725 and that paying 925 to win around 2500 was worth it. Is this an instant call for most of you or should I wait for the button next hand. I obviously want the BB to fold here, but how often do you think the BB will call and check it down with the button?
