re: Poker & Poker Calculators...work?
Totally agree with Grumble. Don't become reliant upon these calculator programs. All they do is prey upon the public's eternal hunger for the easiest way out. The basic information they're giving you isn't anything you can't learn to do rather quickly for yourself. Take that $29.99 and apply it towards a solid poker book, like "Super System" or "How to Play Poker Like the Pros". Or take advantage of the numerous free sites which post http://www.learn-texas-holdem.com
There's no guarantee that you'll win a dime more with these calculators than without them. You can get all your money in on an 80% hand and still lose. The only real guarantee is that you'll never be able to think on your feet, or make your own judgements. Online poker makes you lazy enough anyway by shuffling and dealing, keeping up with your chips, your opponents' chips, bet sizes, betting increments, pot size, etc. My advice is to avoid further atrophy of your "poker muscles".
