Master Class Vol.14 - Vasily Smyslov Smyslov cultivated a clear positional style and even in sharp tactical positions often relied more on his intuition than on concrete calculation of variations. Solutions that are similar to 1.Kb7 f8=Q 2.Kb6 Qb8+ 3.Ka5 Qb5# can be easily averted by adding a black pawn on a5 which would result in the black king not being able to go to a5 and thus no mate! Solutions that are similar to 1.d6 f8=Q+ 2.Kb7 Qxd6 3.Kc8 Ba6# can be stopped by simply adding a black pawn on d6, so that Black’s first move will not be possible.
