Sicilian, Sveshnikov

5…e5 — kick the knight, accept a permanent hole on d5, and get paid in time and bishops.

The idea

The main line is 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5, and everything about it is deliberate: White gets d5 for ever, Black gets …b5, the bishop pair after Bxf6, the half-open c-file and a lead in development that has to be used before the hole starts to matter.

It is the most concrete Sicilian there is. Both sides are following analysis until move fifteen or so, and there is no version of it that can be worked out at the board.

Practise the line

You play Black; the other side answers on its own. Nothing here is saved or graded.

Common mistakes

Three that come up again and again below master level. Each is ordinary opening theory — a named trap, or the error every coach corrects — not a statistic, and not drawn from anybody's games.

…a6 before …d6

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 a6 7.Nd6+ Bxd6 8.Qxd6

The mistake: Chasing the knight on b5 straight away, before the pawn goes to d6.
Why it costs: 7.Nd6+ is a check no pawn can answer. Black has to take with the bishop, and after 8.Qxd6 the dark-squared bishop is gone, the king cannot castle for a while and the hole on d5 has arrived without any of the compensation it was meant to buy.
Instead: 6…d6 first, every time. The move order is not a formality — it is the difference between the Sveshnikov and a bad position.

Recapturing on f6 with the queen

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 Qxf6 10.Nd5

The mistake: Taking back with the queen to avoid the doubled pawns.
Why it costs: 10.Nd5 arrives with tempo on the queen, so White gets the square for free. The doubled pawns are not a defect here — the pawn on f6 holds e5 and the g-file is where Black's play comes from.
Instead: 9…gxf6, which is the move the whole variation is built on. It looks wrong and it is the reason the Sveshnikov works.

The hole without the counterplay

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 gxf6 10.Nd5 f5

The mistake: Reaching the structure and then playing quiet, safe moves.
Why it costs: A permanent hole on d5 is a losing position in slow motion unless something is happening elsewhere. The compensation is dynamic and it expires: …f5 against e4, …b4 hitting the knight, and the bishops pointing at White's king.
Instead: …f5 or …b4, chosen early. The Sveshnikov is not a structure to hold, it is a race to start.
