1.e4
c5
2.c3
A very popular appraoch against the Sicilian. The usual responses are 2...d5 and 2...Nf6
2...e5
Here's a third idea that has not (yet) caught on.
3.Nf3
Nc6
Just like a typical 1.e4 e5 opening but with a funny c3, c5 move pair
4.Bc4
Nf6
Just like the two knights' defense, but again with that funny move pair
5.Ng5
Playing it the same way as the Two Knights. How will the pawns on c3 and c5 effect this variation?
5...d5
Defending the f7-pawn
6.exd5
Na5
As in the two knights' line, attacking the Bc4 prior to re-capturing. Black is playing a gambit
7.Bb5+
Bd7
In the normal line, black can play c7-c6 here. Bd7 is normally a less-favored alternative
8.Qe2
Bd6
Quick development is in order. Black is down a pawn, but will gain time by forcing the Ng5 to retreat.
9.d4
Ambitious... trying to develop the queenside pieces and attack in the center before Black can consolidate the hold in the center
9...cxd4
10.b4
Trapping the knight, but at the cost of permitting black to continue his rapid development.
10...h6
11.Nf3
0-0
12.Bxd7
Qxd7
13.bxa5
So, white is up a whole piece, but white still has five pieces "in the box"
13...d3
Time to play like Morphy. Qxd3 meets e5-e4
14.Qd1
e4
With a threatening pawn center. Nxd5 and f5 are coming
15.Nfd2
Nxd5
16.Nc4
[16.Nxe4
Rae8
wins back the piece]
16...Bc7
Three squares from the knight, a typical manoeuver.
17.Qb3
Kh7
Preparing f7-f5-f4 by taking the king off the a2-g8 diagonal
18.0-0
The white king couldn't safely stay in the center, and the queenside remains relatively undeveloped, but this is dangerous too. Three of black's pieces are aimed at white's kingside, and the Rf8 is about to join in too.
18...f5
19.Nba3
Understandable, but heading the wrong way.
19...Rae8
Otherwise the Nb5, Bb8 move pair seals in the Ra8
20.Nb5
Bb8
Again, three squares away from the knight
21.Rb1
Diagram Relying upon quick counterplay on the queenside. Does black have compensation for the piece?
21...f4
Charge!
22.Kh1
f3
With the simple ides of g3 Qh3-g2#
23.Rg1
Coach's first law, The white king cannot move. All we need is check!
23...Bxh2
Enticing the white king into the open.
