Gives up developed pieces for nothing: a common chess weakness

You trade active pieces for pawn grabs or idle ones

You swap active pieces for things that don't matter. Weigh what you give up against what you actually get.

• vs magnus-com-hack (4/21): the knight went out and came straight back to trade: two moves and a piece's activity gone.
• vs LowtierLoganHNB (4/21): an early f-pawn push gave a pawn back and ruined king safety.
