This question is fairly simple, but simple doesn't mean easy (although for some people it probably is)
Find the fastest possible way to trap a queen in chess from the starting position.
Definition of a queen trap:
- The queen must be attacked by an opposing piece.
- The queen cannot make a legal move without being captured immediately after.
For example, the following was a queen trap achieved on White's seventh move:
(Note: This isn't even close to the fastest possible. It's just an example.)
Clarification: If the queen can trade itself for the opposing queen, or move to a place where it's defended and the only piece that can take it is the opposing queen, it's not trapped.
