So what have we learned today? How to be assertive in chess, of course!
Here are some starters that were brought up in this lesson:
1. Maximize the quality of your pieces.
Simply developing your pieces is not enough. Their value increases as their reach of influence increases, and it doesn't hurt to have them in prime position to attack the king!
2. Play the position by knowing what you want and doing everything you can to make that happen.
Always ask what the position asks of you. After blundering his queen, Player A realized that he needed to take advantage of Player B's exposed king and place his pieces on their best squares to do so. ( i.e. He decided to play his kingside rook to c1 and his minor pieces in the center.)
3. Speed up your development, but not your opponent's!
One critical moment is 13...Kc7 when Black allowed White to develop his dark squared bishop to f4 with tempo.
4. Calculate, calculate, calculate!
White unintentionally gave Black a chance to get back in the game with his interesting move 18. b4, which would have allowed a simplifying 18...Qxe5. He should have first played 18. Nxg4 and then follow with 19. b4 - we saw how this continuation could have played out.
5. Don't give up until the end! (keeping things unclear)
Remember that chess is a game and not a mathematical equation. Just because you are materially "losing" does not mean the game is over yet. Chess ends in checkmate, not when you are winning by, say, 6 points (2 minor pieces!).
6. Be imaginative, but more importantly, be brave!
8. Nxe5 is definitely a blunder, but 18. b4 is a deliberate sacrifice. Instead of holding on to the material that he had left, Player A was willing to give up material in order to improve his pieces and hence further his attack on the Black King. A real life analogy is investment: putting a little money in the stock market is no guarantee, but you will never know unless you are brave enough to make the move. The saying goes, "Fortune favors the brave."
I hope this lesson was instructive and fun, and I would really appreciate if you would leave feedback for ways I can improve.
Thanks a lot and until next time,
