True, this cook can be eliminated in other ways without adding the 1 . . . g2 variation; but there'd still be a dual in the variation 1 Qe1 exf1=B when White could choose between stalemating (2 Kg3, as in the solution) and being stalemated (2 Qf2+, the dual). So if the 1 . . . g2 line is a distraction it's an unavoidable one. | |

| Jan 8, 2016 at 1:06 | comment | added | Noam D. Elkies | Yes, very striking. Is the Black pawn on g3 needed for soundness? If not then normally one would remove it; the extra variation 1 . . . g2 2 Bxe2# feels less like a bonus than a distraction from the theme. | |
