I think he means head-to-head score. Otherwise I agree that it’s a strange statement.

I just heard my daughter singing in the shower "look, I saw rook a4, I just didn't like it". She's 4 years old, doesn't know how to play chess, and doesn't speak English 😲🤯

Just played round 1 of Tata Steel. A hard-fought draw where I was much better but failed to find the correct continuation, and then my opponent found a nice trick to force a draw.
I’ll show the game later. Now I have to sleep…

Just played a game in our team league. Although my team lost 2.5-5.5, I had a nice (theoretical) win. My opponent played into a main line of the Botvinnik Semi-Slav (a super sharp opening), and I happened to know all the theory until he made a mistake.

This is slightly misleading because when Gukesh flagged, Alireza was one move away from winning by checkmate.

The highlight for me was when after 20 moves the position was still roughly equal, and he looked at me and asked "I'm sorry, what's your rating?" It sounded like a compliment to me 😁
Obviously I blundered a piece a couple of moves later...

I think this is one of those "hate the system, don't hate the player" moments. FIDE set this up so this kind of nonsense could happen. In a way, they encouraged it by going only off the Jan 1st rating list.
I don't like that it's happening, but it's not Firouzja's fault.

Nice way to end the year in style: won first place among first boards at my club's end of year team tournament. My team didn't finish very well, but I played some decent games and held a draw in a terrible endgame for 3W 2D 0L 😁

Ra6! Both the rook and pawn are immune: Kxa6 c8=Q; Kxc7 Rxa5; furthermore, the knight has no squares: Nc6 Rxc6; Nb3 Rb6+; Nc4 Rc6.

When I played Wijk aan Zee early this year, I was planning to drive there every day (roughly 40 minutes from my house), but my wife suggested I book a hotel for a couple of days so the kids wouldn’t keep me from sleeping. I love her 😄

Yes. I don't understand how so many people mistake one for the other. You can be both against cheating and in favor of a good process (i.e. against witch-hunting).

I think I’ve seen something like this before. Nxd5 wins a pawn because cxd5 Bc7 traps the queen. After Nxg3 Nxe7+ Qxe7 hxg3 white is a clean pawn up.

I just failed to hold a 100% drawn endgame. I made two blunders in time trouble - one to make it more difficult but still objectively (and easily) drawn and the second to give my opponent the win. I'm furious at myself right now. The analysis will come tomorrow 🤬

Tata Steel Chess Round 3/3. This round determined the final standings - with a win or a draw I would win my group, and with a loss the group would go to my opponent. It ended up as a nice win, and finished "brilliantly" (at least according to
@chesscom
).

I agree. When he went after Hikaru it was funny because he was so obviously wrong abd Hikaru is good enough and big enough to be beyond suspicion, but many talented youngsters don’t have that power and it can have real negative effects for them.

1.Qxe5 dxe5 2.Bf6 Kg8 3.Rh3 and mate seems unstoppable... except in desperate situations we can use desperate measures: 3...Qe1 4.Kg2 Qxf2! 5.Kxf2 Ne4 and black takes the bishop next, stopping mate. In the endgame black is up a pawn.

I played another classical game this week; a very painful loss. I feel that I had a very decent position for most of the game and then suddenly blundered it all away in the end. Nevertheless, here are some positions to think about.

In many situations, once you make a decision, you cannot go back, so you have to live with the consequences. As a result, for important decisions, it makes sense to put some thought into them.
