I should do a post or so on poker since my moniker is Poker Player...

In Texas Holdem, here is some basic information to start thinking about. If it is of interest, I'll do more.

The best way to double your money is to go the cashier's cage. Stop. Take out your money. Fold it over and put it back in your pocket. Go home. (Same will work for Craps, Slots, Blackjack, etc....)

The game was designed for the "drop." That's the money the house takes from each pot and drops down a slot. This pays for them to run a safe, honest, secure game.
Now the drop will vary based on the size of the pot, with a maximum amount. Let's say that would be $3.00.

Look at the number of hands you will play per hour. Multiply that times the drop and you have what you can't win. The typical mid limit game, say $15-$30, will have about 35 hands per hour. That's $115.00 that you can't win, but if you play no hands, you can't lose. If you play say 10 hands, that's $30 you can't win. Let's say you win 3 hands for a combined total of $400, less the drop, or $391. Let's say you loose 7 hands in which you have invested $400. Broke even, right? Wrong. You lost $9.00. To break even you need to win $409. Now I know that doesn't sound like much, but over time it adds up.

Note - A "fast" Internet game can run up to 80 or more hands per hour. So if you are playing on the net you will see a bigger impact.

BTW - Some casinos charge "time." Time is collected on the half hour, say $10, or $20per hour. That's $160 for a 8 hour stint, so you may need to think about playing more hands in a shorter period of time. This is one of the reasons "time" games are looser than "drop" games, irrespective of the dollar size.

Look at the size of the pots you win vs the size of the ones you loose. If your winning pots are all small compared to the pots you loose, then you should consider quitting that game, or change your strategy, if you can afford to. If not, quit.

Card value changes with the number of players. In a 5 handed game big pairs and big cards are more valuable than in a 9 or 10 handed game. But also consider this. If 4 people average seeing the flop in a loose 5 handed game and 4 people average seeing the flop in a medium 9 handed game, the result is the same, right? Wrong. In the 9 handed game there are more hands out, thus it is more likely that the hands will be better on the average. Big card value is inversely proportional to the number of players.

That's a start.
