Benko Gambit Accepted: King Walk Variation

About this variation

White plays e4, allows the bishop trade on f1, and walks the king to g2 by hand. It is one of the main ways to accept the gambit.

The King Walk Variation is 1. d4 Nf6 2. c4 c5 3. d5 b5 4. cxb5 a6 5. bxa6 g6 6. Nc3 Bxa6 7. Nf3 d6 8. e4 Bxf1 9. Kxf1 Bg7 10. g3 O-O 11. Kg2. White builds a strong center with e4, allows the bishop trade, and moves the king to g2 manually. The result is a safe king and a central pawn majority, but White's queenside light squares are weaker.

Black's plans include ...Nbd7, ...Qa5 and ...Rfb8, pressure on the a- and b-files, and ...Ng4-e5 to centralize the knight. Black often plays ...Ne8-c7-b5 to put pressure on c3, which is a key defender of White's queenside.

White's plans include h3 and Re1 to prepare e5, Qc2 and Rb1 to defend the queenside, and Nd2-c4 to block the files. White's central majority gives chances for an e5 break, which can open the position against Black's king.

The King Walk leads to positions where White has a safe king and a strong center, and Black has long-term queenside pressure. It is one of the main lines of the Benko and has been tested in many games at every level.

A common mistake for Black is to allow e5 without enough preparation, which can open the center and the long diagonal for White. A common mistake for White is to neglect the queenside and allow Black to win the a- or b-pawn back with interest.

The King Walk suits White players who like central play and are happy to give up the right to castle in exchange for a strong center. Black players should know this line well, since it is one of the most common ways to accept the gambit.

One concrete continuation is 11...Nbd7 12. h3 Qa5 13. Re1 Rfb8 14. Re2, when White defends the second rank and prepares Bd2 and Qc2. Black continues with ...Ne8-c7 or ...Nb6, and the fight over the b-file and the e5 square decides the game.

It is one of the main lines of the Benko Gambit.
