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:

  1. The queen must be attacked by an opposing piece.
  2. 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:

enter image description here

(Note: This isn't even close to the fastest possible. It's just an example.)

Good luck!

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.


Here's one with three moves:

1. e4 g5
2. Qh5 e6
3. Qg6 h5

  • $\begingroup$ Whoops. Missed that. Added a clarification to the question. (By normal chess strategy, that isn't trapped because white can play something like Qg3). $\endgroup$ – Excited Raichu Oct 15 '18 at 17:18

    $\begingroup$ Wow. This is actually faster than my intended answer (which had it on white's fourth move.) +1 and accepted XD $\endgroup$ – Excited Raichu Oct 15 '18 at 17:34
  • $\begingroup$ Another one is rot13(1. p3 o6 2. Dn4 Ap6 3. Dkn7 On6). $\endgroup$ – Arnaud Mortier Mar 18 '19 at 12:04

Another solution with 3 moves as well, where the Queen is attacked twice.


Here is one on White's 4th, which you consider faster :)

1.Nf3 d6
2.Nd4 b6
3.h3 Nd7

But still not as fast as Jafe's!

Here's an answer that probably doesn't meet what you mean either!
Black "traps" white's queen on move 4

1.c4 d6
2.b4 Bd7
3.h3 Ba4 (Note: at this point the queen isn't trapped)
4.g3 Qd7 (But at this point it is)

I'll keep looking :)

  • $\begingroup$ That's a valid answer. Not the fastest, but valid. $\endgroup$ – Excited Raichu Oct 15 '18 at 17:30
