3 random things you can do to improve your no limit game
1. Watch Ripptyde play an SnG. When he's on his game it's a riot to watch and will open your eyes to just how closely most hands run in value, how many pots are up for sale even against fairly call-happy opposition and that tourney poker is as much a game of stacks and blinds as it is about cards. One of the great moments in my Vegas trip was watching Eric (a move-in specialist) in utter shock as Rippy kept moving-in in front of him. Eric's brother was also in disbelief.
2. Learn to play limit hold'em. It will given you a far greater understanding of the odds and quickly beat you into learning to cope with bad beats. Also, it's far easier to find a live cash limit game than a no limit game.
3. Read Mike Caro's section on 5 card draw in Super System, and/or his section in Super System 2. Lots of great stuff on value and thinking beyond just cards + action. Consider that Mike mastered a game with very little action to base his decisions on.
