[nokkeokd] Switch sides when winning is too easy

A stronger player plays a chess game against a weaker player and gains an advantage, as is to be expected.

When the stronger player feels the position has just crossed the threshold such that converting to a win is no longer interesting, switch sides.  The weaker player then has the challenge of figuring out how to win, which might not be so obvious to the weaker player.  The stronger player has the challenge of defending a lost position, perhaps looking to swindle, which is a good skill to practice.

Switching sides could happen multiple times in a game.  It could happen in multiple consecutive moves, with the weaker player repeatedly blowing full points.

Is this an entertaining way for a human to play or practice against a much stronger chess engine?

Chess task: compose a position and sequence of moves in which the game value changes by a full point every half move -- many consecutive full-point blunders by both players.  Enforce threefold repetition and 50-move rules.  Or more strictly, every move must be irreversible: pawn move or capture.
