kk foldable pre-flop?

[wrestler_118]

If you under the gun against 9 opponents and you hold KK, you will be against AA aprox 4.3% of the time or 1 in 23 times.
If you "know" you are up against aces, you should check your pot odds before you call in an all in.
But since you cant "know" you are up against aces, guess at his possible holdings, calculate the probability of aces, then play accordingly.
Remember, KK will still win 18% of the time.
