In general, the only hands that should be Cold-calling a raise are hands that are too strong to fold (b/c they are a favorite against villains range, have too good of implied odds, etc.) but can't stand a 4-bet.

For example, if a player in MP makes is 4xBB and I have JJ on the button, I could re-raise, but assuming we are deep enough, what am I going to do if he shoves? The short answer is, I have no clue. We've put ourselves in a pretty bad spot. If we can't stand a 4-bet, just call PF.

The key though is to make sure the hand you are cold-calling with is actually ahead of villain's range PF (better than the middle most hand in his range).
