Amazing Queen Sacrifice in the Opening! (Troll Post #1)

I have been doing some deep research into opening theory, and more notably, trap lines.
I found this brilliant queen sacrifice after only three moves. Here's how it goes.

After a typical Sicilian defence by black, white quickly strikes with 3. Bb5!?  
(The purpose of this move is to quickly trade off a minor piece which usually doesn't get much action in a Sicilian. E.g. 3. Bc4 is met with e6 which completely blocks out the bishop from the game)

White has 6 options here. (Yes I know they have 7 but the seventh option isn't played at higher levels so I excluded it from the analysis)

1. Resign, this approach has been taken by a few notable IM's but generally leads to a loss in ELO

2. Offer Draw, this approach is more common than the move above and I have seen many a game end this way.

3. 3. ... Nc6, This move allows 4. Bxc6 followed by bxc6 which does double the black pawns on the C file but allows the black rook to dominate the open B file which according to Stockfish is equal at 0.0.

4. 3. ... Nd7, This move is a bit more awkward because after 4. Bxd7 taking with either bishop, queen or king places that piece on an unnatural square and has to lose a tempo to reposition the piece.

5. 3. ... Bd7, This is a much more respectable move for players who like to play more fluidly as after the knight recaptures on d7 it has more options. Not all these options are good however it requires a bit more precise play from white to maintain the slight advantage. Stockfish gives this +0.3.

Finally, the move you've been waiting for. 3. ... Qd7!! This brilliancy took me by surprise like it probably did you. At a glance it doesn't seem to achieve a better piece placement for either the knight or bishop when they recapture. But you need to look beyond the surface. After 5. ... Bxd7 and 6. ... Nc6, black is ready to castle QUEENSIDE! You may recall the whole purpose of 3. Bb5 was to trade off pieces and castle early. Well this queen sacrifice completely counters blacks plans.

After the exchange and both sides castling the position may look like this.

Both sides have castled and have two minor pieces in the centre. That d7 bishop is eying down areas on whites king side and black is ready to launch all their pawns and break through. Equally, they have a solid defence which will probably require a sacrifice so black still has to play carefully. Stockfish does give this as -1.2 which is only with perfect play from white.

In conclusion, it is incredible how chess is so much more than how many pieces are on the board and more about position and controlling space on the board. I hope you learnt something from this otherwise just finding this amazing discovery.
