re: Poker & missing flopster
Either a bad run, or you're getting bluffed out of a lot of pots. You should have the best cards, on average, about 15% of the time (whereas you've won only 5% of the hands). Do you suspect you get bluffed out of many pots? Otherwise, I'd qualify this as variance, and keep playing.
If you want to plug leaks, post some hand histories (tip: use http://www.zerodivide.cx/converter/
and choose Format: "Bet the Pot" and it will look very pretty and be easy to read!). Pick hands where you feel that you might have gone the wrong way, some way or other. It's a great way to learn new things.
