not sure if this was correct

this is similar to a game i had studied, Karpov v Stein 1971 in which Karpov creates a passed pawn which causes blacks pieces to become cramped

looks suspect but i did not think the queen a very good blockader

creating a passed pawn a la Karpov

look what we get for the pawn, a passer on the sixth about to go to the seventh, an awesome square for the knight and pressure on blacks position

again this is something I leaned from a master game Yurgis v Botvinnik 1931, with queens off, it will be much harder to stop the passer

looks tricky and is tricky but the knight is immune i thought because of the weakness of the back rank

not Rd8, blacks queen and light squared bishop would enter the game, position is razor sharp

as long as dark squared bishop stays on g1-a7 diagonal blacks queen cannot pose many problems
