Bottom line: Unless you intend to steal with that starting hand (by representing a much better hand), you must fold K2 pre-flop. Calling simply to see a lucky flop with that junk is not an option.

Saying you "always get this hand" just means you've conditioned yourself to notice when you're dealt this hand. Try ignoring K2 and looking for how often you're dealt another random junk hand like 94.
