Poker - is not like chess !
How do you play if cards are very poor? and all tournaments you dont have good cards? what you do?
Ahoy there - stranger !
Think, I`m a little bit older than you, so - listen up.
In poker all of player`s deals by random cards, sometime they good - but rare, sometime they just `live` cards (that can win in some cases), sometime they bad (or - very-very bad, depending of your position at the table).
So, nothing matter what kind of game you are play - at the beginning (first 2..5 of circle`s) simply take a deep look to the play of your opponents : how they play specific hands, how often they use 3bet, how often they defends their blinds & etc.
Anyway, the 1st one rule here : patience and attentiveness.
That`s the point !
When you define weak player - mark him, then - try to isolate others and play with him `mano-a-mano`, using his weak. That one of the way - how to make your stack bigger.
Carefully watch - against which player you try to defend your blinds (big a small) : maybe better let him go, when you have the garbage..
And remember all the time : win huge, but lose small !
In other words - if you have the good hand, don`t try to win a little bit. All the time - bet for value !
And vice versa - when you deal by marginal hand, try not lose so much ! You don`t need to anything extra tears and frustration.
That`s the point !
Good luck, brigante !
