Using ICCF Notation

See

https://en.wikipedia.org/wiki/ICCF_numeric_notation

Choose colors for the board and pieces:

cl white #55335588 #FF222222 black 14 mat :

cl WhiteSq BlackSq WhitePz BlackPz 14 mat ≡

Moves are in ICCF notation. There are some online converters from where you can paste a PNG match in algebraic notation and convert it into ICCF, like:

http://marianogappa.github.io/ostinato-examples/convert

This is the example from this site, pasted into the description of some variable. Then call Chess(str,move,sz,cl) where sz is the pieces size. White moves are integers, Black moves ends with .5.

Visualizing positions

This is the original purpose, for problems in probabilistics and discrete maths. Chess (W,B,sz,cl) plots the position given the White and Black information as vectors with the places of the pieces as integers and the piece kind given by a number 1 to 6 for Q, R, B, H, P, K as the decimal part. You can define both vectors manually, or get them calling

W B 12 mat GameICCF description 2500 Chess :

W B 21 mat 23.1 71.6 63.3 11.2 44.5 53.5 62.5 72.5 83.5 19 mat 65.3 56.1 78.6 38.2 27.5 25.5 45.5 67.5 75.5 84.5 110 mat 21 mat

For example
