Being OOP sucks so hard, I really don't hate just c/f'ing.

Raise preflop with K3... WTF?!?

C/F. We are out of position and have reverse implied odds. We are never going to be able to play aggressively enough to realize the full equity of our hand. The pot is tiny. This is a c/f against almost all opponents.
