Guess the square color game

Looking at Magnus evaluating random peoples elo, one of the questions is also what color certain square is. So here is a little game written by ai that lets you practise that.

♘ Guess the square color.

Changelog: Fixed some css issues with scrollers (maybe). History log is now visible in js console (Ctrl+Shift+K in firefox).

The console object provides access to the browser’s debugging console (or terminal in Node. js). It is used to log information, debug code, and interact with the runtime environment during development.

Observation: If you add numbers and the result is even, then the square is black.

a1 = 1 + 1 = 2  = black
e4 = 5 + 4 = 9  = white
h8 = 8 + 8 = 16 = black
d3 = 4 + 3 = 7  = white
