In a similar position sometimes the promotion of the enemy pawn with check may be avoided. A superb example is a study elaborated by E. Iriarte in 1968. The black pawn is nearer to its promotion square; to compound the problem the white king is in the sights of the future black queen. Therefore, it is quite evident that White’s only hope consists in attempting a king breakthrough to the critical squares in front of the black pawn.
