THE HUNGARIAN DEFENCE

Board Position
One of the rarer King's Pawn defences adopted by Black after an initial sequence of steps along the "Épine Dorsale" (a set of moves common to several openings). First given in a manuscript by Cozio (c.1715-c.1780), it is named after a correspondence game between Paris and Pest, 1842-5. Board Position
Black posts his King's Bishop on K2(e7) (move 3b, left), defending his queen (in the event of a later trade-off) and his KB2(f7) by stopping 4.Kt-Kt5(g5).
The defence is usually good for a draw with best play. An early exchange of pawns and then knights on White's Q4(d4) leads to open play (as shown typically by move 10wb, right).
