trading pieces


With that said, there is an advantage to trading pieces for the guy who is winning. maybe he's up material or has a passed pawn or two - whatever it is. In these cases, trading is good (especially queens) because it magnifies the advantage.
example: you have 8 pieces, your opponent has 7. Your opponent has 88% of the material that you do. Losing, but not too badly. Now trade 6 pieces (even trades).. your opponent then would only have 1/2 the material you do.
