re: Poker & Position explanation needed.
Other random stuff I left out of my previous response.
Value betting OOP sucks. If you bet your cards are as good as being face up, if you go for a check-raise that too turns your cards face up and it also risks letting the other guy draw or just check being a marginal hand he'd otherwise be willing to check-call to the river with. - Of course, range balancing comes into play here but having a significant portion of your range being bluffs when OOP is dangerous without being against sophisticated opponents.
Way ahead/Way behind situations suck OOP. Bluff catching across multiple streets sucks at the best of times, having to do it OOP is just unpleasant. You can turn your hand into a bluff, which I prefer most of the time in these situations, but it's value is still minimal.
OOP sucks. I still haven't figured out wtf I'm doing when I semi-bluff flop and turn and miss on the river. Check/folding sucks, bet/folding is even worse.
Overall, playing OOP isn't good.
Also, and this point is really important, the guy closer to the button has the best equity on his raises pre-flop because of his chances of taking the pot down uncontested.
