Something that is happening to me almost every MTT game I play is that I manage to get in a very nice and comfortable position, like top ten in a 500 players tournament, but then I just lose some hands by defending some raises when I'am on small or big blind position, generally bad beats, and I start to lose it, I mean, start to tilt after a while.
Some guys says that it's better sometimes to take a break and even leave the game for a while if the blinds are low and your stack won't be bleeding that much by losing them, but I just can't do it, basically because there will be times that I'll have monster hands and it would be really kind of dumb to let a hand like AA just go away because you are sitting out.
Anyway, I'm really depressed because it happens all the time. I was in such a good place at one of those weekly chromestars freeroll on Pokerstars and lost it all by calling an all-in with AA vs. 88. If i hadn't played that hand I would win a considerable amount of money, it always hit me like a rock when that happens.
