This anon's theory about the Marshall attack, RE: Q Drop 531.
Further reading into the full game of Capablanca vs Marshall, Marshall tried to set a trap for Capablanca at a few different points. Marshall's plan would have sacrificed a powerful piece to enable an unrivaled counter-attack. Marshall tried to temp Capablanca into taking his knight that is attacking the king side of the board. If Capablanca takes the knight then, he likely will be on defense the rest of the game and lose.
However, Capablanca does not take the knight then, and plays the longer position game, and out-maneuvers Marshall.
Capablanca is Trump. The Marshall attack is the cabal's attempt to trap him and take him down. The knight is Pantifa. The knight was close to the king, just as the riots were in DC to Trump.
It will take a few more moves before all of the pieces are developed, and the sleeping rook comes to help cleanup the rest of the Marshall pieces.
I hope it is soon.
