In a position where you've burned some material (and offered a bunch more sacrifices, wisely not accepted) for an across-the-board king hunt, you announce mate in 5, using a quiet move that isn't a check but is forcing.
Then, hours later, mulling the position over in your head at work, find a slight defensive resource, so you rhp-mail a corrected line involving yet more quiet moves, as well as exceedingly accurate defense by your opponent.
Then, when you go to bed, many hours later, the position begins to play itself out in your head, and you come up with ANOTHER defense, to the mate which has expanded to like 9 moves.
So you refute that defense and the insane lines coming off out of it, which include things like the defender saccing his queen for the critical attacking pawn. You start to write this down, in a second corrected mate announcement.
Then, after 45 minutes of analysis, you find that he has a defense whereby he deliberately hangs a rook to make a flight square for the king, and you can't refute that.
You're about to give up and settle for being humiliated when, after making a bold mate announcement, you end up fighting an endgame. A won endgame, yes, but an endgame all the same.
Then you look at the OTHER checking option on move two of your combination. And find a straightforward, simple, nay, effortless mate in 5 (the original number!) One where all the moves are checks, and your opponent has only one legal move to respond to each check. Ie. a straightforward mate, with no possiblity for sneaky defenses, because there are no other legal moves for the opponent.
Finally, you announce your third, and actually accurate, mate!
AAAAHHHHH!!!!
I mean, don't get me wrong, I'm glad for the mate and all, but the lost hours... oh the lost hours.
After the game finally ends, I may post all my crazy lines of analysis here so that everyone can laugh at the mind of an insane person who calculates inaccurate difficult 9 move mates with non-checking moves when there's an easy 5 move mate staring you right in the face.
