Sicilian opening trap

White just played d5 and black moved Ne5.

You will be able to review whole opening after you successfully solve the puzzle.

That's beautiful!

This had "legal trap" written all over it :D

Well played!

I added some more moves.

Great!

Almost forgot to take the bishop. Amazing! Nice sac 

But why is this a "Sicilian opening trap"? Black did not capture the pawn on d4, so it is not the sicilian defence. This is a good trap, but what is the chance for that someone who plays c5-d6 against e4 will not capture the pawn on d4? You can't really use this trap.

To clarify, Sicilian defence is 1.e4 c5. 

3...cxd4 is known as Open Sicilian as far as I know.

I just saw this pattern few days ago studying the Chigorin defence.

Thank You, Plutonia, pattern is incredibly alike mine!

However, white cannot recover the queen, but gets a considerable amount of material for it (2 rooks + a piece?) I believe? Do you have any continuation, I'd love to see it!

I can recapture the queen and remain a piece ahead for nothing.

My threat is to play c7+ to force ...Nd7 Bxd7+ Qxd7 Nxd7, and if Kxd7 Nxd1 and I end up with a piece ahead for zero compensation (totally winning). I'll play c7+ against any black's move, because it's safer to have a clear-cut piece advantage with no counterplay for your opponent. I don't want no funny business with his queen.

If he plays Qc7 then cxb7+ and if he blocks with the knight then I take his rook making a new queen. Note that Kd8 runs into Nxf7#

10 dxc6.  bxc6 11. Bxc6+ Nd7 12. Bxd7+ /NxD7? (the knight is surpsingly misplaced here at d7. It cannot, go for any forks, or attacks at this square the discovered attack is all that is left, but this gives black a move to make room for his king. Losing a knight to keep a queen.) Qc7 (Gotta be carefull here. Qc8 and the queen is lost.) This also puts both pressure on the knight and the bishop.   13. Nf6+ Kd8   14.  Bxa1 Qxa1/Dxf6....   15. Kxd1...   White got a rook, and a knight for a queen. losing.

Now following the bishop line. Qxd7. 13. Nxd7 Kxd7 14.Kxd1

Tied. If black did not block with the knight, and with the queen instead. white would be winning, but since black sacced his knight white must lose his bishop and knight in order to get blacks queen, whereas black only sacrificed a bishop to get whites queen.

Obviously Nxd1 for that last move. Much safer for white.

Very nice variations. 

But what would happen if black played e6 or f6 after white played 12. Nxd7?

Can you count? White is a piece ahead in that line.

No, I guess i can't....

Nxd1 is correct :)

I was taught to ALWAYS take the d4 pawn in the Sicilian.  NO MATTER WHAT.  Well, that is how they taught things when I was in high school.  Anyway, I can tell you from a friend of a friend let's say, that, well, your center tends to just collapse if you don't take d4.  I mean this was drilled in to the point of just being part of the opening, as in, "oh I just learned this great chess opening, it's called c5 takes d4, pretty cool, huh?"  Also, the Sicilian defense, in my opinion, is bit of a misnomer.  It is really more of a counter-attack, and taking on d4 is attacking, albeit usually in a somewhat limited sense of the word.  If you're playing white and move to d4 and it isn't captured, seriously consider advancing the pawn to d5.  It basically says to black, "we're playing my game now, joker."  And your knight is in my way."  That's fine, but if you are the type of player who wants white to just play their game, then don't play the Sicilian, play the Hippo or something.  Obviously these are generalizations.  Anyone who can point to a Sicilian where it's not advised to take d4 as black, I would be very appreciative.  No really, my entire adolesence and young adulthood would surely be given new meaning.
