+  | Both players play a move "at the same time".
+  | Conflicts are resolved following a few simple rules.
+
+p.
+  In order to not rethink a big part of the code, the white move has to be
+  played before the black one. However, the black player doesn't see it.
+
+p So both players play "at the same time". Resolving rules:
+ul
+  li.
+    If both moves arrive on the same square, both pieces disappear except
+    if one is a king. In this case only the king remains.
+  li.
+    If a capture was intended but the target moved, the move is still played
+    but doesn't capture anything.
+p.
+  Such captures can be anticipated by capturing our own pieces.
+  If the enemy captures as predicted, his piece disappears.
+  If he doesn't, the self-capture isn't undone.

+p.
+  When the king is under check, a legal orthodox move must be played.
+  Some weird situations would occur otherwise, like on the following diagram.
+  If we allow self-(re)captures then the king would take on h2 and escape to
+  the third rank.

+
+p.
+  Due to the simultaneity, it is possible that a king is captured for example
+  after escaping a check in a wrong way, as the following diagram shows.
+  So, capturing the king counts as a win, of highest priority.
+  A checkmate wins too, but if your king is captured and the other still on
+  the board (even if it is mated), you lose.
