Don't you just hate it when you get a bad beat in a big spot? It's never good for morale when your flopped set doesn't hold when your opponent nails a runner-runner flush.
Or what about complete coolers? It can hurt when you get your kings in against aces and you don't get there. Sometimes it seems like when this is the other way around, your opponent always gets there but in fact the percentages usually even out over time.
We can't promise you a holiday present of no more bad beats or coolers. This is all part of poker and something even the top pros in the game get frustrated by.
