Positional Exchange Sacrifice

Have anyone tried the daring positional exchange sacrifice in their online games? I saw this powerful technique in GM games and they are subtly beautiful. Please post your personal games featuring positional exchange sacrifice.

What is a positional exchange sacrifice?  Giving up space for a long distance mate or better position in a few moves?

My favourite way of sacrificing the exchange is by 1.h4 2.Rh3

This doesn`t necessarilly actually happen in the first 2 moves but it can be useful in situations where the light squared bishops are of special relevance.

Looks like none below masters level would try positional exchange sacrifice. This is one of my favorite game Kasparov - Shirov 1994

17. RxNb7! What a daring sacrifice!

Sacrificed my knight to go on the attack, which proved to be fruitful.  Was also okay with droppng the rook.  =)  I hope this qualifies.

McKornKid, it's not positional exchange sacrifice but it's very daring. You got chess guts .
