Schlesinger ignored the details of some of the alternative, counting and non-counting advantage plays, when they were not precisely quantified for him. By quantified I mean that the edge they provide was not precisely proven and specified.
Grossjean provided much of that and became admitted to the Master's Board DS has setup on rge21.com in response. But real players using these techniques have little need to specify such, they are too busy applying..., even while they are greatful that Grossjean spelled such returns out.
But the process by which Schlesinger fell behind in these studies continues due to his pendantic ways. And the progress made by those who dared to continue their investigations--witness too the demands for specific data that I rejected even from Wong here on banger play (it would have been too clumsy to conceal writing observations down with my act)-- will leave them further behind, and the demands for such formal specification will likely either lead to further conflicts between Grossjean and the rest...witness the dustup over the SCORE numbers given by Grossjean, or constrain Grossjean to fall behind further with them.
So one can either wait until still newer oportunities are fully evaluated, and lose out with Don and his clones, by not playing them until all the returns are specified, or they can recognize Grossjean as a master advantage player who took the time to specify those returns without disclosing too much, and continue to apply those and even newer valid alternative advantage plays. But that risks a 3rd alternative: that of holding back ourselves just because a master advantage player is aligned with a conventional crowd that tends to impead newer research, and thus fall into the same trap Grossjean might fall into.
