The trick taking power of a bridge hand is estimated with Milton Work point count, of which we shall implement a version that is simple enough for beginners of either Python or the game of bridge!

Looking at a bridge hand that consists of thirteen cards as tuples (rank, suit):

• give it 4 points for each ace, 3 points for each king, 2 points for each queen, and 1 point for each jack. This raw point count is then adjusted with the following rules.
• if the hand contains one 4-cards suit and three 3-cards suits, subtract one point for being flat. (Flat hands rarely play as well as non-flat hands of equal point count.)
• add 1 point for every suit that has 5 cards, 2 points for every suit that has 6 cards, and 3 points for every suit with 7 cards or longer. (Shape is power for the declarer.)
• if the trump is anything other than "notrump", add 5 points for every void (that is, suit without any cards in it) and 3 points for every singleton (that is, a suit with exactly one card), both of these for any other suit than the trump suit. (Voids and singletons are great when you are playing a suit contract, but very bad in a notrump contract. Being void or a singleton in the trump suit is, of course, extremely bad!)

Hands are often given in abbreviated form that makes their relevant aspects easier to visualize at a glance. In this abbreviated shorthand form, suits are always listed in the exact order of spades, hearts, diamonds, clubs, so no special symbols are needed to show which suit is which. The ranks in each suit are listed as letters from "AKQJ" for aces, faces and all spot cards lower than jack are written out as the same letter "x" to indicate that its exact spot value is irrelevant for the play mechanics of that hand. These letters must be listed in descending order of ranks AKQJx. If some suit is void, that is, the hand contains no cards of that suit, that suit is abbreviated with a minus sign character "-". The shorthand forms for the individual suits are separated using single spaces, with no trailing whitespace.

Your function must return a number of points and a shorthand form of a given hand.

Input: Two arguments. List of tuples of two strings (str). String (str).

Output: Tuple or list of integer (int) and string (str).
