Wayward Queen Attack

I don’t think it is a bad enough move to be “defeated” without White making some mistakes. Though Black equalizes easily.

(Note that I am not the OP; he left, and I’ve inherited the thread!)

 

This is how I defeat it!

I am not the OP, btw. He seems to have disappeared.

3...d5 is bad. After 4. BxP, White gains a pawn for nothing, and Black still has to address the Qxf7# threat.

4...g6?? 5. BxN+ PxB 6. Qxe5+ (+/-)
4...Qe7?! 5. BxN+ PxB 6. Nf3 Nf6 7. Qxe5 Nxe4 8. O-O (±)
4...Qf6 5.BxN+ PxB 6. Nf3 Bd6 7. d3 (±)
4...Nh6?! 5.BxN+ PxB 6. Qxe5+ (±)
4...Be6?! 5.BxB g6 6. Qh3 PxB 7. Qxe6+ (±)

3...g6! 4. Qf3 f5!? is way better:

5. PxP Nd4 (White has many options after this, but all are good for Black.)
>6. Qg3 Qf6
>> 7. Bd3 d5!
>>> 8. Nc3 Ne7
>>>> 9. Nf3 NxN+ 10. QxN e4 (Semi-unclear; Black gets a piece up, though White has some compensation.)
>>>> 9. Nge2 Nexf5 (Better for Black)
>> 7. Bb3 Nxf5
>>> 8. Qf3 Nd4
>>>> 8. QxQ NxQ 9. Nc3 d5 where 10.Bxd5?? or 10.Nxd5?? are both mistakes because of 10...NxB 11. NxN Nxc2+ (-/+) and 10...NxN 11. BxN Nxc2+ (-/+) respectively.
>>> 8. Qc3 c6 with d5 following. (Edge for Black)
>>> 8. Qd3 c6 with d5 following. (Edge for Black)
>6. Qc3 Qg5! (Black attacks g2 and later c2 via bishop and knight. White stays on the defense. Black is better)
>6. Qd1 d5
>> 7. Bb3 Bxf5 (Black has a space advantage. After 8. Nf3, Black should immediately pin the knight with Bg4, double attack it with the knight, break open White’s kingside by trading knights, and deploy the bishop to h3.)
> 6. Qd3? d5 7. Bb3 Bxf5 (Black is superior here).
>6. Qd5 Qe7 (Nxc2+, Nf6, and c6, are all looming threats.

5. Ne2 Nf6 (Passive, but definitely playable) 6. Nbc3 Na5! (Black is doing fine.)
5. d3 Nd4 6. Qd2 b5! 7. Bb3 fxe4 8. dxe4 Bb7 (Black is practically better.)
5. BxN RxN 6. Nc3 fxe4 7. Nxe4 d5 8. Ng3 Qf6 (Black is better, yet again.)


So yea. 4...f5 is way better, in my opinion.

 

This is what positions could arise after 3.Bc4 d5! 4.Bxd5
