3-check is not chess
The object in chess is to bring the opponent's king into checkmate. In 3-check is... to do 3 checks
That was Roger's claim. But my argument was that 3-check is a form of chess since it inherits all of the piece movements and victory conditions — the only difference is that it grants players one additional play to win the game. Using the logic you gave, one could also argue that bullet chess is not chess since the objective is primarily to "flag" the opponent instead of playing good moves to checkmate them.
For clarification, note that I will consider this "adoption" a 3-check adoption, nothing more.
Wha?
