PUBLIC MARKS with tag sen-non-sen

The lengendary swordsman Miyamoto Musashi mentions the three sen (before, ahead) as a method of strategy by taking the lead or initiative. Taking the lead, initiative requires you to see through the opponent's spirit and strategy in order to defeat him. Practicing sen falls into the realm of keiko in which each opponent is different, and each timing and strategy instance is unique.
