 The defense is named for János Balogh (1892–1980), who was a Hungarian International Master of correspondence chess, and a strong master at over-the-board chess.The opening is rarely seen today because it weakens Black's kingside somewhat and often results in a backward e-pawn and/or a hole on e6 after Black's light-square bishop is exchanged.International Correspondence Chess Master Keith Hayward has recently written a series of articles arguing that the defense, though risky, is playable.
