A "Round-the-Corner Straight" is a sequence beginning low and rapping around high, such as: 3-2-A-K-Q. This one ranks as a 3 High Straight.
A "Five & Dime" is a hand containing a 5 and a 10 with three unpaired cards in between. It beats Triplets (and Skeets) but looses to any Straights (including Round-the-Corner and Dutch Straights).
A "Skip Straight" [also called an "Alternate Straight" or a "Dutch Straight"] is a sequence of every other card, eg: J-9-7-5-3. It looses to a standard Straight but beats Triplets (and Skeets and Five & Dimes as well).
A "Four Straight" (four cards in sequence) beats a Pair but looses to a Four Flush. Likewise, a "Four Straight-Flush" beats a Four Flush but looses to Two Pair. When played with Four Flushes, but no other freak hands, this is called "Canadian Poker."
A "Big Bobtail" is a four card Straight-Flush (eg: J-10-9-8 of Spades) and a "Little Bobtail" is a three card Straight-Flush. Big Bobtails beat Full Houses but loose to Four of a Kind, and Little Bobtails beat Two Pairs but loose to Triplets.
A "Skeet" [also called a "Pelter"] is a hand containing a 9-5-2, with one card a 3 or 4, and the other a 6, 7 or 8. It beats Triplets but looses to any Straight (and Five & Dimes).
These four unpaired hands beat a Straight but loose to a Flush: "Big Tiger(or Cat)": [K---8], "Little Tiger": [8---3], "Big Dog": [A---9] & "Little Dog": [7---2]. Big hands beat Little of the same, and any Tiger beats any Dog.
A "Four Flush" is four cards of the same suit, which beats a Pair but looses to a Two Pair. When played with no other freak hands, this game is called "New York Poker."
