-Later:
-Let choice of time control, allow correspondance play, several games at the same time
-==> need to use indexedDB instead of localStorage. Maybe with Dexie https://dexie.org/
-Each user would have a unique identifier stored in the client DB.
-Allow to cancel games (if opponent doesn't connect again)
-Identity would be browser-based: different games on smartphone, home computer, work computer... (why not ?)
-Index might still look the same, and variant page would have another tab "Games"
-==> running, and finished (which can be deleted from local memory)
-(A true analysis mode could be implemented also, to navigate in completed games --> use a button)
-Allow challenging a specific player (by his chosen name)
-But keep the random pairings as main playing way + always playing in ZEN mode,
-except when accepting an individual challenge.

+Squatter Chess: safe on last rank = win
+Companion Chess : pieces of same nature don't attack each others
+Crossing Chess = win when the king cross half-board
+Crown Chess: place all units on move 1 (similar to Sittuyin, more freely --> in own half-board, possible pawns on 1st rank)
+Medusa Chess = Isardam
+--> à chaque déplacement, check attaques directes + découvertes autour de case de départ dans 8 directions (pas caval)
+
+Kingmaker: pawns can promote also into enemy king
+--> no king tracking, getCheckSquares + underCheck test all kings
+
+Eightkings: 8 pawns + 8 kings (non-royal until the last remains?)
+--> yes seems better, no king tracking + no underCheck/...etc when >= 2 kings
