rather difficult to promote, since they can offer little shelter to their own
king. If White had no pawn left on board, the position would be winning for
Black. He would simply place his queen on a central square (say, d5) by means
of succesive checks and then start to advance his pawns little by little. The
exposed position of the white king would make perpetual check impossible for
Black, since in certain moments counter-checks with exchange of queens would
follow. However, the modestly looking f3-pawn changes the situation a great
deal, by offering to the white king a reliable shelter and indirectly allowing
the own queen a higher liberty of checking the enemy king. Black's win, if
possible at all, is connected with huge practical difficulties.} Qa2+ 74. Kf1 {

trying to transfer the king to the queen side (for example, b3 or b4) would

possibility of a deadly countercheck on the b-file. After an eventual echange
of queens the king would remain in the square of the f-pawn, while his own
pawns would be unstoppable. If White would advance the f-pawn at an earlier
stage, Black could adjust his plan and bring his king back to the centre,
because the enemy king would suddenly become more exposed. All this sounds
rather abstract, but it would have probably offered better practical chances
to Black.} (75... Ke6 $2 {would lead to an immediate draw by means of a
