re: Poker & Gap Theory. Good, Bad, what is it?
Here is the POSITION thing in my humble opinion.
If you are early to act, you can not play hands because folks may raise behind you. You have less information as to who is coming and who may raise, and what the action maybe behind you. Ther for, if you are going to play from an ealy position you need a hand that will stand up to any action from players to your left. As you get closer to the button, there is less of a chance of action making your hand unplayable, so you may enter pots more liberally.
The gap theory states that a better hand is required to call than to raise.
For example if someone bets and you have AA, there is safety in calling. You have the best hand so there is less worry. You may choose to raise, but you are safe to call. Your hand is thht good, if you called all the way you are stating that you believe you can win a showdown. If on the other hand you have AQo calling a bet gives you concern. The possible holdings of the betting player may have you beat. A call serves no purpose and your hand is vulnerable. A raise however could get your opponent off of many of the possible holdings, giving you an extra way to win by him folding. Also, you decrease the action behind you. They would be coldcalling a bet, and a raise, which gains you better postion.
So the gap theory states that it takes a stronger hand to CALL with, than it does to RAISE with.
(by the way I am not condoning raising with AQo as a general practice. It is there to demonstrate a point)
Great topic and posts, I live for this stuff!
