the chess analogy is a good one.
but i think it appears even in regular training. it is perhaps a lot more subtle than other martial arts and it is not trained in a competitive sense. we train from a static grip all the time and the chess feeling can be seen when you go to move and uke shifts his power or centre so you awase to take it again..... its all blending always.... same for kaeshi waza. it exists but perhaps you need to search for it, and it doesnt feel complete because we dont really train in a sparring or competitive situation...... chess after all is a competition between two people.
