Scrabble: the Game, pt 2

Game details
The game is played by two to four players on a square (or nearly square) board with a 15-by-15 grid of cells (individually known as "squares"), each of which accommodates a single letter tile. In official club and tournament games, play is always between two players (or, occasionally, between two teams each of which collaborates on a single rack).

The board is marked with "premium" squares, which multiply the number of points awarded: dark red "triple-word" squares, pink "double-word" squares, dark blue "triple-letter" squares, and light blue "double-letter" squares [In 2008, Hasbro changed the colors of the premiums squares to orange for TW, red for DW, blue for DL, and green for TL]. The center square (H8) is often marked with a star or logo, and counts as a double-word square.

The game contains 100 tiles, 98 of which are marked with a letter and a point value ranging from 1 to 10. The number of points of each lettered tile is based on the letter's frequency in standard English writing; commonly used letters such as E or O are worth one point, while less common letters score higher, with Q and Z each worth 10 points. The game also has two blank tiles that are unmarked and carry no point value. The blank tiles can be used as substitutes for any letter; once laid on the board, however, the choice is fixed.

Notation system
In the notation system common in tournament play, columns are labeled "A-O" and rows "1-15". A play is usually identified in the format xy WORD score or WORD xy score, where x denotes the column or row on which the play's main word extends, y denotes the second coordinate of the main word's first letter, and WORD is the main word. Although unnecessary, additional words formed by the play are occasionally listed after the main word and a slash. In the case where the play of a single tile formed words in each direction, one of the words is arbitrarily chosen to serve as the main word for purposes of notation.

When a blank tile is employed in the main word, the letter it has been chosen to represent is indicated with a lower case letter, or, in handwritten notation, with a square around the letter. Parentheses are sometimes also used to designate a blank, although this may create confusion with a second (optional) function of parentheses, namely indication of an existing letter or word that has been "played through" by the main word.

Example 1:

A(D)DITiON(AL) D3 74

(played through the existing letter D and word AL, using a blank for the second I, extending down the D column and beginning on row 3, and scoring 74 points)
