Ive had a few decent tourney results, however i really dont know if im suited to tourneys. All they seem like to me is just races and who gets lucky and for a while now i dont win the ak v JJ or whatever....everytime. Some ppl i watch appear to run really hot in those and others dont. I just dont get how you can succeed in tourney poker when you race poorly. cash games just never or rarely all in preflop. Can you adopt a style in tourneys that avoids all ins? I am moaning a little i know, i would just like to know how you do well at tourneys when you lose a lot of races.

Yeah, MTT's require a large bankroll due to the un-godly variance that comes along with it. Just play MTT's that are within your BR, you should normally have 100x buy-in to play a particular tourney comfortably. But going on huge stretches of not cashing in them is very common..so don't be too discouraged.

I guess i expect too much from tourneys...i did win quite a lot on betfair, but it is the deepstack tourney so i guess you were right when you said stick to slower games...they just take so long and pokerstars and full tilt have like 1000 ppl or more every fucking tourney?

I don't think you should completely rule out tournys. As some one quite rightly said above, the variance just kills yah! The way I deal with it, is to mainly play cash games, but online I like to get in on the 6 seater 3/4k garunteed reg/fast blinds as they suit my tourny play to a T! So just play the structures you do well in and stick to those...
Choose the battle field that gives you the advantage is the way i see it :P

Well, that's two different types of poker. Cash games often have a quite slow structure, it's a little more about strategy and reading the ppl on the table. Most tourneys (especially online) have a fast structure and you don't have much time to play strategic or wait to check out the others on the table. It may be that cash game are your cup of tea but it won't hurt if you try to improve your tourney game.

should i stick to cash games?

Yes

I was a steadily losing donkament player up to a couple of months ago and I can assure you that these cheap tournaments are very beatable, there's just a few concepts you need to absorb that aren't used a lot in cash games. Maybe you're just blindly 3xBB or pot raising instead of adjusting your raise size to account for the stack sizes of yourself and the players left to act? You could also be playing too tight once the blinds are relatively large and the antes have kicked in, especially once you're in sight of the bubble. If you're constantly shortstacked then you will always be just a coin flip away from elimination. You need to take some calculated risks after the early madness is over in order to get your stack to a comfortable level so you can play aggressively without putting your tournament life at risk. Most tournaments will still have a sad ending no matter how well you play so turning a profit is a matter of scooping the top tier prizes on those occasions where luck favours you

Tourneys are MUCH more luck intensive and MUCH less reliable. Most successful tourney players are backed for just those reasons. You can expect long losing streaks in tourneys but in cash games if you are good you can have much more control over it.
