playing position

is there anything online that anyone could recomend or any tips you have to share about theory of position play.

Uh have you been reading FTR at all?

Like any other part of poker, you can't just take position as a discrete strategy - it is too tied in with stack sizes, table texture, villain aggression, your image, etc. etc.

Perhaps try asking a more specific question or two, maybe giving an example, and we might be able to tailor our responses to your needs.

basically you want to only play out of position with really strong hands, AND as the aggressor.

The problem with being out of position is that any bet or raise you make shows extreme strength, and any check you make shows extreme weakness. Decent players in position use these cues to efficiently read your hand.

You counter this by sometimes checking good hands and bluffing weak ones, but generally you'd rather be in position, where your actions do much much less to reveal your cards.
