How Much Do I Think That Player Will Call?


Having a good idea of how much another player will call is important to successful wagering. The goal is to figure out what kind of player you are facing and his current mood. If you cause another player to get upset or emotional, that person will probably call must more frequently. If you are playing against a tight player, you may need to bet smaller amounts in order to keep him in the pot and get more money out of him or her.
Always pay attention to the betting patterns of opponents. If a person is betting large, you may want to increase the size of your wagers a bit. Also, be aware of check-raises so that you do not get led into betting when you should realize you are probably holding the losing hand.

Right-sized Bets

Using a strategy to betting the correct amounts to get the most value from your ahnd is important. In No-Limit Hold'em, this can really pay off. In a short-handed game with a maximum buy-in of $600 and blinds of, let's say, $3/$6, there are some very effective techniques you can employ.
$30 raise - Use this really big raise in pre-flop situations only when you hold a prime hand. Because it is an even number, it seems to make other players want to call with ease. If you throw in a $100 chip, that will surely intimidate other players and fail to draw them into seeing the rest of the hand by calling your raise.
$24 raise -High pocket pairs work well with this raise; use it when you hold a 10-10 or better. It's a bit smaller than the $30, but more intimidating than a $20 raise. Odd numbers, like $23, seem to be scary to players, so raise in that sum only when you want to reduce callers.
$12 raise (double raise) - Don't use this raise frequently or avoid it altogether. Never use this raise with pocket pairs of Aces or Kings. This raise simply gives you a poor table image.


Ascending Bets - This is a truly b wagering technique. When you hold Aces or hit the hand you want on the flop and seek callers, keep betting a little bit more every betting round. Get those your opponent committed to the pot and it is likely the player will stay until the end. You goal is to have the opposition so pot-commited that by the river you can pull him all-in and take the stack.
These are only a few examples of how to improve your wagering skills and results. Try them out, use them where they work best for you in your personal style and table image and win that extra money when the cards fall just right.
