i think its an ok question because it reminds me of a recent situation..

me: kk
some other guy preflop bet from early pos
me: 3bet
other guy: all in
my: "looking at this guys tightness and ultra fast all in this stinks to high hell of AA, but i have KK so ill give it a crack" call
other guy wins with AA

im only laying down KK in this situation if something stinks that bad again. and even then im tempted to call
