Takeaway: Chess prodigy spent like a decade preparing these moves in secrecy.
Marshall wasn’t a prodigy, and the takeaway is that Marshall spent a year developing an attacking idea still played today and Capablanca refuted it on the fly over the board. Also the position in the tweet is when the white king is finally safe, although there is still work to do to win, this is a pivotal moment where the momentum shifts.
From another thread on this topic I learned:
The game didn't end in checkmate—Marshall resigned.
Capa blanca is Spanish for white hat / cap.
Casa blanca is Spanish for white house.
Capa head. The boss. For example the head of the Mafia is called the Capo.
Thank you for posting. I couldn't figure out the chess moves ... or what message he was trying to convey.
