Trading down to win
Simplifying toward an endgame specifically because your material or structural edge gets clearer, not smaller, as pieces come off.
It sounds backwards — trading pieces when you're ahead feels like giving your opponent chances — but a genuine material or structural edge usually gets MORE decisive as the board empties, not less. Fewer pieces mean fewer tactical chances for the side that's behind to complicate matters, and an extra pawn that looked marginal in a crowded middlegame can be simply winning once it's a clean king-and-pawn or rook endgame.
The skill is picking which trades to invite: swap off the pieces that give your opponent's counterplay, and keep the ones that convert your specific edge (an active rook, a better minor piece, a passed pawn).
A player who only knows how to press with pieces on the board misses an entire winning method — sometimes the fastest way to win is to remove the very things your opponent needs to make trouble.
Avoiding trades while ahead because 'more pieces means more winning chances', when in fact the extra pieces are exactly what's keeping the game unclear.
