||One of the rarer King's Pawn defences adopted by Black after an initial
sequence of steps along the "Épine Dorsale"

(move 3b, left), defending his queen (in the
event of a later trade-off) and his KB2(f7) by stopping
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).
