Above we ‘ve focused on pairs, threes of a kind , and so on. By chance or by design , if a bloody minded spectator tries to trip you up upon a repeat performance ad handpicks the cards to be used you may find yourself presented with ten cards of different values. Regardless of the suits present , you now have ten if thirteen possible values, and it turns out that the odds of having six values in arrow such as 2 3 4 5 6 and 7 are even . In such cases , if cards are arranged so that the 2 and 7 are the first two , and the 3 4 5 and 6 are the last four , you will certainly get a straight . of course the spectator may end up with a better straight , if the other four cards are an 9 10 and jack , but at least it ‘s still interesting.
