What chess games have violated commonly accepted principles? There are certain chess principles that generally should be accepted and followed. I was wondering If anyone knew of any game or games that have gone against these principles and still resulted in a win from the player who violated the principles?
Here are some principles we teach beginners but grandmasters regularly break.



Don't bring your queen out too early.

This principle was successfully broken by Korchnoi in an important match.

Develop your pieces!

Here we see Polugaevsky successfully play his own variation where he uses the queen to grab a pawn, and then start to think about developing the minor pieces around move 15.

Don't move the same piece twice in the opening.

Although Kasparov didn't win this game, he should get an award for moving the same knight 5 times in the 9 first moves.
