Short-handed NL holdem?

I like to play tournments and SnGs alot. The problem with that is that after awhile the statisticals change when there aren't as many around the table. Are there any good information on how one should play heads-on, 3, 4 and 6 players. I realize that the way to play got to change alot between these situations. At least more then it is between 10 and 9 players (it's just a drop with 10 % from 10 to 9, whereas 3 to 2 is 33% drop ).

Have you read the books Harrington on Hold'em vol 1&2? Otherwise I can really recommend those, as they cover both play from the start and then have a good, large section about the endgame (that one is vol 2). They are only about NL tournaments, both big ones and SnG's. Get them if you can!

HOH I and II are THE books that anyone with any skills you've played against has read.

How funny, I ordered them yesterday without seeing your replies.

Thanks alot anyway.

I play at Paradise. I like doing the 5-max and 1-on-1 tournaments as practice for bigger ones. Now when it gets to the end of a tournament, I feel like I'm just getting into my comfort-zone.
