Crazy Queen sacrifice in the Italian opening! Even engine doesn't see it coming!!

Do you like when someone sacrifices their queen and end up winning in absolutely brilliant fashion? I am gonna show you one such brilliant queen sacrifice that can happen even in your games. (I had it myself).

 We start with one of the most popular openings at all level. The Italian opening:

 Then after 3.Bc5 4. d3 Nf6 5. Bg5 d6 6. O-O we arrive at the following position:

Now we chase the white's bishop with 6.h6 7.bh4 g5 8. bg3

The surprise starts now . We play h5 here, threatening to trap the bishop with h4. But notice white can play Nxg5 and go for an attack on the f7 pawn, which resembles the knight attack or the fried liver attack.

WE DON'T CARE! we trap the bishop with h4! Then after Nxf2, the best move for black is Qe7 after which engine gives advantage to black( at a high depth). But we will discuss another move here. We will take the bishop with hxg3, SACRIFICING OUR QUEEN!. After knight captures the queen,

Engine doesn't see it coming!

Lichess Engine at a low depth thinks this is winning for white. But in reality, after 11.Bg4 black is slightly better if white plays correctly . Otherwise black is just winning.

The line goes: 11.Bg4 12. Qe1(top engine move) Nd4!

There is only one move where white survives, black remains only slightly better. That move is h3!.After which you can play Ne2+ winning the queen. If white doesn't sacrifice the queen,he gets mated :

13Ne2+ 14.kh1 Rxh3 15.gxh3 Bf3#

Looks cool, right?

Now if white doesn't play h6. He plays some other move, for example Nxb7 (saying: there's no threat ,I will just grab another pawn 😂.I had some games like that.). We play the amazing move Nf3+. You have to take it (otherwise Rxh2# next move).After 14 gxf3 Bxf3 Mate is unstoppable. I will leave it up to you to find it.

white to play, mate in 4 for black

Note: A similar variation was played in a famous game where Mikhail Chigorin was Black. This is sometimes called the Chigorin's trap for that reason.
