Another example is the first round of a freezeout tournament when an opponent goes all-in and you hold KK. Unless you know your opponent may make this move with a range of hands you cannot call. KK is not a good enough hand on which to go out of a tourney in the first round - only AA qualifies on this score.
I totally dont understand this? Your behind to 1 hand. I would be licking my lips at the chance of a first hand double up.
