Sometimes i think something along the lines of hmmm...I wonder what piece of my opponent is on a really good square and then I take it not worrying about losing material in the process of taking it.
Kinda a way of eliminating your opponents best player.
P.S......Disclaimer I am not advocating shanking anyone in your next basketball game in order to get rid of the opponents best player.

I tried 2 sacrifice material but many times it doesn't work out. Can you guys please explain what are things you consider before sacrifice of material?? Perhaps if you could post ur game along with comments like what was ur thought process and why you think its good time 2 sacrifice??
