If you look on the study closer and even ommit the introduction, you see that my study is different (even I didn’t know before about the specific study of Zinar). There are 7 or 8 sqewer checks in my study compared to much less in Zinar study. And the main line and main promotion of h-pawn is completely different from Zinar’s study. The main purpose of the study was to achieve maximum number of sqewer checks and I succeded in this.
The author added an ugly introduction to Zinar 1982.
