This game is a good example of what happens when you forget the four principles I laid out the other day. In this case, I became so focused on cornering his Queen and removing it from the board with minimal loss to myself that I neglected to notice just how much a threat that piece was. I did start to get nervous about the encounter the longer it dragged on, but apparently I wasn’t nervous enough to check the board thoroughly for vulnerabilities, and it cost me the game.
