No-limit Texas Hold'em Tips
Playing too many starting hands:
In a $2-$4 NL game you should have a 20-30% view of the flop percentage. This means folding AJ in first position, KT in middle position and QT in late position.
Table selection:
Only play in games where you have an advantage. You want a few weak players at the table when you sit down.
"Playing the players":
Make sure to quickly assess the opposition: who plays inferior hands, who folds at aggression, who bets with draws, who calls big bets with weak hands and draws, who can be bluffed, who bluffs, etc.
"Pump it or dump it":
Fold or bet/raise (if the odds are with you). You should avoid calling unless you have a good reason (like trapping an opponent).
Respect most big bets and raises: this is particularly true on the turn and river as most players do not bluff.
Basic Pre-flop Strategy
Most of the time you should raise or re-raise with top-pairs (AA-QQ) and top connectors (AK, AQs) in order to make low-pairs pay to see flops against you. Remember, they will often have the opportunity to double up on you if they hit.
Stick to premium hands. You will pay severely to "chase" with second-best hands in NL.
Keep most raises down to between 70% and 100% in order to save money when you get re-raised or called by stronger holdings. If there are limpers in front of you, raise to about 4-6 times the big blind.
Have respect for strong tight players (ie, you should drop AQ if a strong player raises under the gun).
When very weak players have entered the pot, be sure to call and take flops with them.
Tournament Strategy
Tournament poker is one of the world's hottest fads. In 1972, the grand prize at the World Series of Poker (a $10k buy-in) was only $80,000. In 2005, Joseph Hachem took home $7.5 million. The reason for this major increase in prize money is the number of players that have entered tournaments. In 1972, only 8 players entered the world series of poker, in 2003 there were 839!
Game Structure
Don't forget that blinds increase during the tournament, The bigger the blinds the bigger the pots. It's not only about winning big pots but about stealing big blinds. The players become tighter, they're not ready to risk with their big stacks. The players choose between "fold' and "raise". This is considered to be the best tournament strategy. All calling stations go to hell at early states of the tournament.
As the blinds increase, the number of players decrease - so you should be not only tighter but also be more aggressive.
Big Stacks Vs Small Stacks
Take the size of the big blind and multiply it by six. Say, the big blind is $100. $100x6 = $600. If you have more than $600 then your stack can be called average. Big stack = average multiplied by two. If your stack is less than $600, you can't scare anybody with that. And it's not the only disadvantage. The other thing is that youreally can't harm those with the big stacks.
If you're a lucky big stack holder then you can be like Doyle, tight-aggressive. But keep in mind that it's very easy to make the stack small, but it's much harder to make it big again. You'll come to the conclusion that it is rather safe than sorry to call a player with a small stack.
