Coercion theme missing from puzzles.

"Coercion involves forcing your opponent to move a piece to a square where it will be vulnerable to another tactical motif."

In this puzzle lichess.org/training/Z3hzJ, the king is being coerced to a square it will be forked. This theme should be added IMO. Upvote if you agree.

This sounds very similar to what lichess calls "attraction".

Attraction is for king
Coercion is for pieces

Lichess says Attraction is: An exchange or sacrifice encouraging or forcing an opponent piece to a square that allows a follow-up tactic. Coercion is when you force the piece with threats, not exchanges or sacrifices.

True, that's a difference, although I think it's small enough that the two could be filed in one category. So maybe lichess should expand the definition slightly: "A move encouraging or forcing an opponent piece to a square that allows a follow-up tactic."
