From Beau Geste Data:
Texas TEAMMATE is your personal partner for your live or on-line Texas Holdem games. You simply enter your cards as they are dealt and Texas TEAMMATE instantly provides easy to understand advice and information. As soon as you enter your Hole Cards, specific guidance is given...which you can heed or ignore! If your cards are weak, fold now to avoid throwing away chips chasing a hopeless hand. But if you have strong Hole Cards, consider making your opponents 'pay to play'! After the Flop and the Turn, Texas TEAMMATE will show you the 'OUTs'...cards that will improve your hand. You are also shown where your current hand ranks compared to what your opponents might already have AND you'll also see what is the best hand you can hope for. If you have lots of OUTs and/or your hand is strong, bet aggressively. But if your OUTs are few and your cards are weak it might be time to Foldem...or bluff! Novice players will quickly gain confidence and improve your skills. Just be sure to shield your Texas TEAMMATE App from the jealous eyes of your opponents!
