SuperBlitz #14: Tunnel Vision

I’ll admit tunnel vision in a blitz game can some times come back to bite me but luckily in this game I was focused on a decent line instead of overlooking a major threat. My opponent also had their own hyper focused idea which followed mine the next move but luckily I realized and corrected my oversight before they managed to have a chance to. We’ll get to the position later in the game as it happens near the end when I was winning and got a bit complacent.

The first interesting thing about the game was the opening we played. It was a QGD Anti-Nizmo where Black still played Bb4+. If Black is playing this line it’s best to know the proper moves to follow it up because anything but the best line gives White an advantage right from the start.
1. d4 d5 2. c4 e6 3. Nf3 Bb4+

The whole point of White playing Nf3 here is to dissuade Black from playing the Bishop to b4 and instead using it to break the pin on Nf6 when it’s played. Black plays it anyway and white has a few replies. My favorite and what I played in the game is Bd2 immediately challenging the bishop. This is where most people go wrong, the best move is to retreat the bishop to e7 since capturing with Bxd2 means Black has moved the bishop twice and I will get to recapture with knight or Queen developing at the same time. Most people don’t want to retreat and will capture or even worse will play Nc6 giving white an advantage from the opening.

Here is my mistake: I have the option to recapture in e6 with the rook or the knight. Clearly the knight is better as it forks the two rooks but I recaptured with my own rook with the idea of doubling and then infiltrating the 7th rank. I had done this very thing so many times in so many games I did it without considering anything else. As I said before the move was fine but it wasn’t as good as winning an exchange.

It’s Black’s turn to move and miss an idea: They choose to play Nc4 getting the knight to a great outpost and threaten a3 which I would have to defend by moving my rook to a passive square. The problem is the looming knight fork on the King and rook on g6. Black does win the pawn but at the cost of a rook and eventually the 7th rank.
