If you keep putting yourself in a situation that you opponents has 15% to win the hand and you have 85% to win the hand you are playing excellent poker. the cards are going to do want they want. but if someone needs to hit a card to win you playing good poker and eventually the cards will fall in your favor and you will take a tourney down.

IF you cant buy a hand, take a break or watch poker or read about poker. or move down in limits and build you bankroll back up.
