Sometimes, duplicated cards are accidentally Chop Moved through a mistake or through a complicated situation. When this happens, it is pointless to use a clue to "undo" the Chop Move - the team can just continue to allow the player to discard normally.
Subsequently, if someone does use a clue to undo the Chop Move, there must be a good reason. This means that the card they were about to discard is important, so the player should discard the now-known useless card and then permanently Chop Move their new chop.
Sometimes, a desirable card is on the next player's chop and it is not directly cluable. In this situation, players can cleverly use the various kinds of chop moves in order to save the card (e.g. Trash Chop Move, 5's Chop Move, Tempo Clue Chop Move, and so forth).
However, none of these chop moves may be available to perform. In such a situation, players can Chop Move a player by giving them a clue to make them intentionally misplay the clued card. This works in exactly the same way as a Trash Chop Move, except that it the trash is not known to the player receiving the clue (and it costs the team a strike).
For example, in a 3-player game:
All of the 2's are played on the stacks.
Bob's hand is completely unclued.
Alice clues Bob red, touching one card on slot 1 as a Play Clue.
Bob assumes that it is a red 3 and immediately plays the card. However, it is actually a red 4 and it misplays.
Bob knows that if Alice is not making a mistake, then she must be trying to communicate something special. Similar to a Trash Chop Move, Bob can reason that multiple cards in his hand are important. He marks slot 2, slot 3, slot 4, and slot 5 as being Chop Moved.
The Misplay Chop Move is the most costly type of chop move, so it should only be performed in a situation where no other kind of Chop Move would work.
Remember that as a special exception, Scream Discards do not apply when a player has a "blind" card to play in their hand and the blind card can exist in your hand.
Thus, when this occurs, you will usually want to blind-play your Finesse Position card, since this sequence of events indicates an Ambiguous Finesse.
When you blind-play a card in this situation and it misplays, it means that the unusual discard really was a Scream Discard after all, so you should treat it like a normal Scream Discard and permanently Chop Move.
This is called a Hesitation Chop Move for short, since it was triggered by a (failed) Hesitation Blind-Play.
