Greetings JMack,
Usually after 1...d5, I will opt to play the more aggressive 2.c4 leading to open lines of play in the infamous Grob Attack. Here rojor went with the closed prophylactic Grob leading to closed or Grob Gambit Declined lines. These lines require less preparation for the Grob player and can lead to tricky positions, but lack the sting value of 2.c4. Nevertheless, rolor did play well here up to the blunder. If you are interested in studying the Grob Attack in more detail, you can check out my powerful repertoire built with Houdini at the following link:

This morning I was challenged by rojor60, a 1794 rated player. I always accept challenges, even when I know I'm going to get my butt whipped. Rojor60 (playing white) used an opening I had never seen before. It's called Grob's Attack. I had no idea how to defend against it and made what I hoped were the best moves at the time. I did end up winning because of rojor60's blunder on move 20 (his move 20. Rg1 cost him the game. He should have moved 20. Ng1). Take a look at the game and see if there is a better way to defend against this strange opening. You just might see someone play this opening against you (hint).
