Forget the opening theory and the variations in this game for a moment. It’s a favorite of mine because all the pieces seem to align in funny diagonal geometries.

26.Bg7+ A very pretty shot. Possibly my opponent was expecting a queen retreat and a draw by repetition. I think the constellations of black pieces (h7-g6-f7-e6-d5) and white pieces (the light square pawn chains) are curious, with the most notable diagonal alignment being this final concatenation from d4 all the way to h8. Fittingly, none of the vertical-moving rooks ever played more than a bystander role for either side.
26…Kxg7 27.Ne8+ 1-0
27…Kh6 28.g5 and of course 27…Kg8 28.Qg7 are both mate.
Come to think of it, this game has not one but TWO into-thin-air tactics: 26.Bg7+ and also 17.Bh6.
