I was, basically, The Psychiatrist From Armageddon for Halloween, primarily because I already owned a lab coat and had access to an anechoic chamber.

There is no better feeling than when you have a losing position in a chess game, your opponent gets mad at you for not resigning, and they attempt to showboat instead of just checkmating you, and then they screw up the win.

Pretty sure this was a new endgame for me: R+8 v. R+8.

Game seven, bottom of the ninth, tie game, bases loaded, two dudes crashing into each other, and it somehow works.

ABC News has apparently been bullied by Vladimir Kramnik into deleting an unspecified video.
Kramnik is an incompetent buffoon whose bluster and legal claims are always absolutely insane, which leads me to believe that ABC News' policy is just to retract any video that anyone makes a claim against.

Yesh. I think about that a lot. Also, we were 83 votes away from him never being governor in the first place!

I won very quickly. I played pretty well, too, for my level. I think Danya would be proud of me for this one.

I always play this opening with white. The highlighted move is uncommon, but it's what Danya recommends, so I call it "The Naroditsky Variation." And every time someone plays this against me, I know that they learned it from him, and thus they are going to be a good player.

I think it's super cool that my niece's public elementary school is using fundraising tactics that are indistinguishable from ActBlue, which are in turn indistinguishable from a scammer trying to steal my credit card.
