To play blind chess, we must visualize the chessboard in our mind without seeing the board. Blind chess helps to improve: Visualization Memory Focus Calculation Board awareness We give numbers to files to identify square colors quickly. a = 1 b = 2 c = 3 d = 4 e = 5 f = 6 g = 7 h = 8 Example: a is 1 because it is the 1st file b is 2 because it is the 2nd file Ranks are: 1 to 8 Color Rule Black Square odd + odd even + even Examples: a1 = black b2 = black h8 = black ___________________________________ 1. Chessboard Coordinates Basics A chessboard has: Files = columns → a b c d e f g h Ranks = rows → 1 2 3 4 5 6 7 8 Example: a1 e4 h8 Each square has: one letter one number 2. Square Color Trick (Very Important) BLACK Squares Rule If both are: Odd + Odd Even + Even → The square is BLACK Examples: a1 → odd + odd → black c3 → odd + odd → black b2 → even + even → black h8 → even + even → black WHITE Squares Rule If both are:...
