i keep getting it with the best hand doesnt matter the acr/global/pokerstars i cant win a damn flip and when i win the flip i getting guted on the turn and the river 8 out of 10 hands over my last 250 hands
First of all 250 hands is a completely meaningless small sample. Even over 25.000 hands there will still be significant variance in both cash games and tournaments. So the main thing is to adopt a long term view on poker and stop worrying about short term results. I know, its easier said than done. But really try to reduce the amount of times, you check the balance in the cashier or open your tracker to study your results.
For instance its probably common for a lot of us to always check our results at the end of each session. But try to force yourself to not do it. Just close your tracker without even looking. And then spend your time and energy to review those hands, where you are unsure, if you made the right decision. Maybe post some in the forum and hear the opinion of others.
Now for this to have a chance to work, its important to be well bankrolled, so that short term variance dont mean huge swings in the
bankroll and the potential threat of either having to move down, go broke or make another deposit. So try to play overrolled. Like maybe 100 buyins for cash games and 300 for MTTs. For many people that will calm them down and make them worry less about a few losing sessions.
