Setting up the clock with a 5 second delay and giving each of us 75 minutes (how the tournament in Des Moines will be timed), I sat down with Jerad for a game at Impact. Jerad was black. After black’s13th move (Be6), we found ourselves in this position. I made a careful calculation and found what I thought to be the best move. See what you would do as white in the following position.
Seeing the domination of my rook on the e-file, I found 14. Bxc6. This turns out to be a fantastic move if black does not respond accordingly, but a sub-par move to 14. Bxe6. If the bishop takes the knight here with 14. Bxc6, what is black’s best response? Do you retake with the pawn or queen? The best move is to take with the pawn, as taking with the queen is a blunder! By taking with the queen, you leave the bishop hanging on the e-file. So, after 14. Bxc6 Qxc6 15. Nxd4, white comes out a piece ahead.
Why is 14. Bxe6 better? After 14 … Qxe6, white begins an attack on black’s knight with 15. b5. In this situation, if black decides to move the knight to safety, then 16. Nxd4 is next using the relative pin on the e5 pawn. Black’s best response would be 15… Qa2 which attacks white’s rook as well as removes the relative pin on the e5 pawn.
Through several blunders (for both of us) we arrived at this position. In hind-sight, this should be finished every time against the most difficult of computer engines by white.
Embarrassingly, with plenty of time on the clock (over 10 minutes), I let the time get to me and did not calculate out the position. While at some point, I would have to sacrifice my bishop for the pawn on the a-file, doing so immediately leads to a draw as there is no way for my king to take out both black’s pawns AND keep him away from the h8 square. In hind-sight, it is easy to see that Bc7 is the correct attacking move to ensure the win.
