We may easily deduce that in knight endings of four against three pawns on the same wing the prospects of the weaker side to save the game will be considerably better. However, many authorities on the matter – R. Fine, L. Portisch and Y. Averbakh, as well as the “Encyclopaedia” generally erroneously consider the afore-mentioned positions as won! The simplest case is when the weaker side has not got any pawn weaknesses and is able by blockade to “calm” the play. The ending of the game V. Petrovic – Smagin, Novi Sad, 1986, shows that even a protected passed pawn is not sufficient for the win.
