Quickest Queen Trap?

I'm wondering if this is the quickest queen trap possible. I guess I should make my definition of a queen trap clear. If Player A traps Player B's queen, then any move by Player B that does not result in check or threaten Player A's queen will allow Player A to immediately capture the queen with a net material gain for Player A. This definition is probably not perfect, but hopefully, it's sufficient.

1. e3 e5
2. Qf3 d5
3. Bd3 e4
4. Bb5+ c6
5. Qf4 Bd6

If you find a faster one, or even one equal in length, please post it here. I'm curious about this.

This one could be faster if you just played 4.Qf4 Bd6 right away.

A curious one:

1. D4 C6 2. Bd2 Nf6 3. Ba5 B5 4. B4



Curious cos it's basically just fools mate, and instead of setting up this position where black's queen is trapped, white could have just taken the queen XD

Not the best solution, SGs is the best, but yeah.

Good point. It was a momentary lapse of thought. I'm somewhat impressed with a trap within 3 moves though.
