-End of game a bit too verbose: should just say "Black win" ... + show PGN
-Styles must be improved (full width for smartphones, selectable text for PGN...)
+For animation, moves should contains "moving" and "fading" maybe...
+Depth 2 or 3 depending on variant and if we detect smartphone or not?
+(static get SEARCH_DEPTH() { return 2; })
