Best position: On Button. Next best positions are the seats to the right of the button. Worst spot are those to the left of the button. Position is important because of information. You gather more information by acting last.

Best strategy(tight, loose, etc.): depends on the players you are playing against, stack sizes, position, table image, etc. (there is no definitive best style).

Changing gears:You can do this throughout the game with or without less players. It's good to change it up to keep your opponents off track on what style you are playing that night. The less players = hands worth more. example: KT is shit with ten people but a monster with 3 or 4.

Play small pockets for sets only early in the night. Later on though, they tend to be strong hands.

Suited connectors: see the flop for CHEAP ONLY. Don't call big raises with them.
