plang: After 19..axb Boleslavsky said:
"Black has played the opening inaccurately and as a result"
1) the d7 square, needed for the transfer of the knight via c5 to d3 is occupied by the bishop;
2) White has obtained the possibility of occupying the f5 square with the knight f3, retaining the second knight for the d5 square;
3) the f5 square, because of the absence of the h pawn cannot be covered by the g pawn"
<Boleslavsky believed that here 34.Rxb5 Qxb5 35.f6 would win forcibly>
Well, the move he played (34 Rxe5) was certainly sufficient.
