This game shows the power of knight forks, and it also shows that you should always be looking at your pieces before you move them. Check to see if they fall into the usual knight-forking positions when knights are close! Try putting two pieces on a chess board, and put them in a bunch of different ways that make forks so that you can get a good idea... that or you can play like black did in this game until you figure it out the hard way.
Btw this game really did happen, and I was pained to be white, hoping something surprising might come.
