To paraphrase, "That is the very first and the very last time you will ever beat me in your life!"- Korchnoi (to Sophia Polgar after losing a blitz game) Can be seen on YouTube. http://www.youtube.com/watch?v=TxeiGipoFSE

"You do not give pawns to Grandmasters"- Kortchnoi to Ruben Felgar when Felgar's Benko failed at the 2005 Najdorf Memorial.

Wow, what a bad loser.

Never initiate exchanges that allow your opponent to develop a piece on the recapture.

"Modern chess is too much concerned with things like pawn structure. Forget it, Checkmate wins the game." - Nigel Short

I'm keen on studying checkmates lately.  I started studying mate patterns after I read that good chess players rely on pattern recognition more than anything.  

Yea I used to love playing just casual games where they got obsessive about the structure and I just focused on the mate. Yep its all patterns you just black out the pieces on the board that cant get involved and just work out the move order.

Just found this one don't know if it already posted that made me smile anyway.

“The Pin is mightier than the sword”
(Fred Reinfeld)

Every move is equally significant, so is every piece. Respect your openent enough to play only your best moves.

One move at a time - not one game at a time - has been my winning formula.
