e5
The Sveshnikov (or Pelikan). A controversial opening... the ...e5-pawn push creates important weaknesses on d6 and d5, but the opening has become a key grandmaster response to the Sicilian.
6.Ndb5
Aiming to play Nd6+ which would gain the bishop pair
6...d6
Preventing Nd6 but establishing d5 as a central hole for white to eye.
7.Bg5
To exchange off Black's Nf6 which exercises some control over the key d5-square.
7...a6
Taking the opportunity to force the Nb5 to retreat to the rim
8.Na3
b5
The obvious threat is b5-b4 winning a piece. White has two good ways to sidestep the threat.
9.Bxf6
Most grandmasters swear by Bxf6, but Nd5 is also playable.
9...gxf6
The double pawns actually assisdt black in gaining counterplay with f6-f5 and down the open g-file with Rg8.
10.Nd5
Having taken the Nf6, white occupies the key central square.
10...f5
The immediate counter attack, hoping for exf5 eliminating white's d5-anchor.
11.Bd3
A popular continuation, though the bishop; interferes with the Qd1's communication with the key d5-square.
11...Be6
And so now this is a problem for white... Bxd5 will place the e-pawn in the hole. And by attacking the Nd5, Black answers the threat of exf5.
12.0-0

Ne7
The variation with Nd5 permits white to maintain the knight on d5. This variation is far more double edged and black has hope for a counter-attack with e5-e4 and f5-f4

This looks like the new move in this game. The idea is simple enough. When white moves the Na3 towards d4 or e3, the Rc8 will be able to move to c5 to capture the white d5-pawn. [16...0-0
