The Exchange Sacrifice Unleashed

·       
The relative value of pieces is
perhaps the most difficult chess concept of all to explain. ·       
Why so much talk about such or
similar sacrifices? Quite simply because we are afraid! We have been taught,
and practice shows and proves the clear fact, that the closer we get to the
last part of the game, the ending, the more pronounced a material advantage
becomes. ·       
Maybe less so with tactical
sacrifices, where we immediately see what the sacrificer gets in return.·
