“all-in” is certainly used in the sense of “all-inclusive,” “comprehensive,” “excluding nothing,” so if that’s Lindner’s intended sense, then “all-in strategy” would cover it. (M-W tags this sense of “all-in” as “chiefly British” – to what extent that accurately reflects current usage, I can’t say.)
