happens a lot to everyone.  no one is immune.  i just hate it when it's kick the kat day. 

Just understand in the long run the odds will straighten out.  Sewage happens that is why man invent the toilet!  K K is the second best hand to start with.

I also have learned the hard way not to limit my options.  All ins take away every thing ( position and options ) when you do it, and most likely there is only going to be a 50 - 50 chance for you to win.  Pocket Aces have a 80% chance of winning pre flop.  Which means in reality with Pocket Aces you will be in big doo-doo 20% of time!

A way I think about all hands since they are just 2 cards and the flop tells the true strength.

You are in doo -doo 20% of time with As before the felt shows cards period.  So I look at chip stack of the all inner first , then their position before looking at where and from bubble are we.

Free roll or real money I try to play same way!  Unless I am sharpening my poker senses by doing poker exercise such as just playing top 20 hands of my choice and nothing else.  You do fold some good other hands but I know my discipline and patience have to be kept in line so every here and there I just do it.  I also reevaluate my latest play which will tell me to do this.

Hope that answers your question without confusing you!
