how to win

1. Learn core principles.
2. Apply them in slow games.
3. Analyze your decisions afterward.

This is the framework I use with students I coach.

Sleight of hand and being a smooth talker helps irl.

I have no idea! @ChessMasteryOfficial, I'm not even sure that analysis afterwards helps. I find that even when according to the Game Review I didn't play badly, I still arrive at completely lost positions. Here's an example; no moves highlighted as inaccurate, 88% accuracy, materially ahead, but utterly lost, with my opponent having two devastating attacks on my e5 pawn, my central pawn structure facing complete demolition, my king exposed and uncastled (meaning that one of my rooks might as well not be there because it's paralysed up a corner), and I've got no meaningful attacks whatsoever. Winning is actually hard...
