I ordered a book called How to Play the Sicilian from amazon, and I soon hope to have a review of it for everyone out there. Until then, I recently played a game that had a position that was somewhat beautiful. If not beautiful, it was at least interesting!
It's black to move. The move Nxd3+ should be immediately apparent. I don't know why white moved the king to b2 here, probably a case of time pressure and not expecting the knight check in the first place. But here you can see the absolute power of the Knight. A Knight can be interesting because when it attacks other non-Knight pieces the attack is never mutual. Here the Knight is forking every single kind of piece (other than another Knight) and they are all helpless against him!
