Thanks for the kind remarks.
Yes, I was very happy to find 42. ... Rf8 over-the-board. It made possible my later 50. ... Rf7 and 51. ... Rg7! with a very pretty simultaneous defense (on the rank) and counter-attack (on the file).
The only other over-the-board find that I felt as good about was a NEW (?) piece sacrifice on move 8 (!) that I discovered in a QGD Tchigorin game here on this site:
I played this game years ago, in the final round of an OTB Tournament in the Canadian Maritimes.
I've shown it before on this site... a couple of years ago?... but I'm a shameless attention-whore and I'm posting it again.
The game had a strong effect on me at the time. It was a back-and-forth struggle sweeping in waves over the whole chess-board, including all four corners. Just as I was breaking through to the enemy King, my opponent launched a last-ditch counter-attack that came within an ace of mating me.
It felt like a sword-fight with rapiers, at the edge of a cliff.
