In checkers/draughts competitive play means random picking a three move sequence and then the players swap over after the finish and play again...
Is it possible in future chess might see more thematic input to keep chess alive ?eg you must play at least one 1e4 game in a Swiss tournament and AVOID the Sicilian in all games as black ....lots of variants
Interesting -- "I cut, you choose."
Mightn't it be better yet to have the first player make a move for white, and then have the second player decide whether he wants to choose a side, or play a response for black and throw the choice back to the first player?
Would greatly reduce the number of Sicilian players, methinks.
