Why can't cashgames be 10bb deeep?

Ok so its offical, i really suck at cashgames.

Since ket makes $8394058349058 an hour playing 3/6, and he sucks at poker, i figured i'd give cashgames a go. WOW it was just me losing money. I have no idea whats up with mu cashgame play, most of the times i got stacked ket said he'd play the same as me, but jesus he runs sooooo much better than me.

In other news i came 2nd in the 35k 10r last night, lost HU pushing 20bb vs a button limper with 55 (terrible i know...) and QTh looked me up for 1/3 of her stack? LOL I race good and obv lose and come 2nd.... covers my cashgame loses tho.

I really don't know what to do with poker right now. I rape sngs so badly, my tournament game is pretty good (im a proven winner at both) but i suck so bad at cashgames. I guess it would make sense to not play cashgames, but meh all the money is there.

I move house 29th june, and the plan is to get a 3rd monitor and start playing a bit more seriously. Whether that means 10 tabling sngs alongside 4 mtts, or whether i can actually get good at cashgames, who knows.

PS - OXY HOW CAN YOU NOT BE PWNING SNGS ALREADY?! EVEN ASTROMECH DONKEY CAN WIN AT THEM (i kid!)
