So, first two cards are handed over, and it is necessary to make
the first decision. Thus it is necessary to consider following
factors:
Force of your cards (the more strongly, the better) - usually it
is necessary to play no more than 30 % of hands, only the strongest.
Your position (the later, the better) - in the end at you
already is the information on rates of opponents, you can make more
exact decisions and not be afraid raise.
Bets before you (the more limpers (limper - the player
speaking call on preflop), the better, raise - is worse) - the more
than players, the sweat if your card will drop out not there is
more, you lose only small bet but if to you will carry on flop, you
will win much.
Type of game (passive/aggressive, tight/loose) - aggressive
players can lift with mediocre cards, loose players will answer
yours raise with a bad card.
Your image behind a table - if you behave as tighter (tight
player) against yours raise maniacs or owners of really good cards
will play only.
Force of game yours and - the is better you play opponents in
comparison with opponents, the it is possible to play hands more,
you receive the at the further stages of game.
