TODO

   1 Simultaneous games: view Game + Simultaneous, using component (One)Game
   2 Storage: just key ID => IDs of actual games (in indexedDB)
   3 In Hall challenge: acceptation on sender side (who launch the game when ready --> left click [which just delete if nobody registered, with confirm box])
   4
   5 Tournaments: merge with tournament.auder.net code. At the beginning, still admin / users. Later : admin / supervisors / users
   6 => recurrent tournament, eg. every sunday (late?) afternoon + wednesday evening, Discord-vote for variant?
   7
   8 Issue: embedded rules language not updated when language is set (in Analyse, Game and Problems)
   9 Also: if new live game starts in background, "new game" notify OK but not first move (not too serious however)
  10 On smartphone for Teleport, Chakart, Weiqi and some others: option "confirm moves on touch screen"
  11 (=> comme pour corr) + option "confirm moves in corr games"?

  19 Squatter Chess: safe on last rank = win
  20 Companion Chess : pieces of same nature don't attack each others
  21 https://www.chessvariants.com/difftaking.dir/brotherhood.html
  22 Crossing Chess = win when the king cross half-board
  23 Crown Chess: place all units on move 1 (similar to Sittuyin, more freely --> in own half-board, possible pawns on 1st rank)
  24 Medusa Chess = Isardam
  25 --> à chaque déplacement, check attaques directes + découvertes autour de case de départ dans 8 directions (pas caval)
  26
  27 Kingmaker: pawns can promote also into enemy king
  28 --> no king tracking, getCheckSquares + underCheck test all kings
  29
  30 Eightkings: 8 pawns + 8 kings (non-royal until the last remains?)
  31 --> yes seems better, no king tracking + no underCheck/...etc when >= 2 kings

  35 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.
  36 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.
