The probability is that in any card game
The probability is that in any card game each player will in the long run receive an equal number of good, bad and indifferent hands, and most Bridge experts agree that a skilled partnership will, in the long run, score more points than a less skilled partnership. This means that skill rather than chance is the deciding factor in Bridge. But Bridge partners, no matter how skilled, must always play a series of bad hands out to a finish and take their beating. This is not true of Poker.
In most forms of Poker
In most forms of Poker the game is pure chance only until the players looks at the cards dealt him. From then on, unlike in Bridge and most other card games, chance plays a lesser role, because the players need not play bad hands out to a finish. The player can throw a bad hand in and take a small loss, or perhaps none, or he can continue to play a bad hand and sometimes win by bluffing. In Stud and its variants this decision can be made by the player each time another card is dealt until the showdown. The skilled Poker player will play fewer bad hands than the unskilled player and thus increase his winning chances in a way that an equally skilled Bridge player cannot do.
