King's Gambit Accepted: Kieseritzky

What Is The Kieseritzky?

After 4...g4 White refuses to retreat and plays 5.Ne5, planting the knight in the centre where it eyes f7 and attacks the pawn on g4. 5...Be7 is not a developing move, it is a hit on h4. Black threatens ...Bxh4+, which wins a second pawn and forces White either to block with g3 or to move the king.

White replies 6.d4, taking the centre and giving the knight a defender, then develops with Bxf4 and Bc4 to hit f7. Everything turns on the f4 and g4 pawns: keep them and Black's extra material tells, lose them and White's development plus the open f-file wins. So finish development and move your king off e8 before White opens lines.

How Do You Beat The King's Gambit Accepted: Kieseritzky?

There is no reliable record for this position, so this is understanding rather than a frequency. Black has developed the bishop to e7, which prepares to challenge on h4 and quietly asks White what the compensation actually consists of.

In every King's Gambit line the defender's job is the same: finish development, then give the pawn back at the moment it buys safety. The bishop on e7 fits that plan because it covers the dark squares White wants and prepares castling. Do not go pawn hunting on the queenside while the f-file is open toward your king. Once you are castled and developed, the extra pawn is simply an extra pawn.
