getRepetitionStatus() lose or draw... (for some variants)
Chakart: king remote capture, is an option if short range

WON'T IMPLEMENT:
Simultaneous games: view Game + Simultaneous, using component (One)Game
Storage: just key ID => IDs of actual games (in indexedDB)
In Hall challenge: acceptation on sender side (who launch the game when ready --> left click [which just delete if nobody registered, with confirm box])

Tournaments: merge with tournament.auder.net code. At the beginning, still admin / users. Later : admin / supervisors / users
=> recurrent tournament, eg. every sunday (late?) afternoon + wednesday evening, Discord-vote for variant?
(Can be replaced by still separated tournament.audeR.net, using vchess credentials...)

Embedded rules language not updated when language is set (in Analyse, Game and Problems)
If new live game starts in background, "new game" notify OK but not first move (not too serious however)
On smartphone for Teleport, Chakart, Weiqi and some others: option "confirm moves on touch screen"
(=> comme pour corr) + option "confirm moves in corr games"?

Crossing Chess = win when the king cross half-board
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

https://boardgamegeek.com/boardgame/18661/alapo
Alapo is a strategy game. Each player owns twelve abstract pieces, two each of six different kinds. Round pieces move in any of the eight directions on the 6 by 6 board; square pieces move only orthogonally and triangular pieces only diagonally. Large pieces move any distance, small pieces only one field per turn.
Opponent pieces can be eliminated by moving onto their position. The goal is to reach the opponent's base line with one of your pieces without the opponent being able to eliminate your piece in his/her next move.
