// FIDE Handbook C.02.2.2 Height,weight,proportions
// 	- King – 9.5 cm, 
// 	- Queen – 8.5 cm, 
// 	- Bishop – 7 cm, 
// 	- Knight – 6 cm, 
// 	- Rook – 5.5 cm and 
// 	- Pawn – 5 cm. 
// 	- The diameter of the piece's base should measure 40- 50% of its height.
// 	- These dimensions may differ up to 10% from the above recommendation,
// 		- but the order (e.g. King is higher than Queen etc.) must be kept.
// We are going to transgress C.02.2.3
// FIDE Handbook C.02.3.2 Size of the square and the board
// 	- The side of the square should measure 5 to 6 cm. 
// 	- Referring to 2.2 the side of a square should be at least twice the diameter of a pawn’s base (it means four paws on one square).
