[qqgxthpx] Logical long endgames

The moves of a long chess tablebase endgame, for example the 517 move KQNKRBN, are often described as defying logic. Find a different move sequence, probably longer, which makes fewer logic-defying moves.

Perhaps formally define what logical moves are. Then, the defender should try to induce the most logic-defying moves, not necesarily the longest defense.
