Chess.com USCF Online Blitz rated tournament decent result




It says 22 players, but that doesn't include the 12 who dropped out.

I got as high as 1888 blitz rating points before I lost to a lower rated player knocking me down around 30 points.  Overall I had a net gain of 6 points.

It sure would be nice to break 1900.

Stockfish 10 vs. Stockfish 9

When Stockfish 9 came out, I did a speed chess round robin between Stockfish versions 6, 7, 8, and 9, and all the games were draws except for the games played by Stockfish 9, which won all its games against the older versions of the engines.  That is a significant difference.

I analyzed one position with Stockfish 9 and the new version 10 running at the same time.   After 5 minutes, Stockfish 10 was thinking 1 ply deeper in the same position..  Is that significant?   Probably.  For most positions the engines would be very similar, but being able to think half a move deeper than your opponent usually makes you unbeatable, because you already see all the variations that your opponent is going to think about.

Both programs ran at roughly the same number of nodes per second.  Given that this is a 27-28 ply search, achieving 1 ply deeper probably means that 10 has to eliminate about 3% of the variations that 9 looks at, by my calculation.  This could also mean that 10 has a weakness that 9 doesn't.  Or this could mean that 10 has a better evaluation function, leading to more variations being eliminated.

Third Place in the USCF Online rated speed tournament was a surprise.

There were some higher rated players who dropped out before the final round, probably because they lost to the top player with the monster rating.   It says "17 players", but that doesn't include the 18 who dropped out before the final round.

I had a couple of games that I really should have lost, but won anyway.  I made many errors, but so did my opponents.  This happens sometimes in speed chess.  My last round opponent literally had me in a mating net and threw it away.

Position from last night

This is not the most deep position in the world, because White is already winning, but I think that the method that I used to finish the game is somewhat interesting.

Budapest Gambit

2018-09-19

My best tournament result.

I didn't remember what year the tournament was, but I found it.  I got a draw against soon to be Grandmaster Igor Ivanov and came in second.

This was a time when I felt like studying tactics was really helping me.  Just looking at my rating progress, I went from 1800 even to 1927 in just 5 months, but it would take another 9.5 years before I would hit 2000!


There were a few other good results in recent years like ..


and getting the Expert trophy at the class championship a couple of times.   Of course, winning the senior championship 3 times didn't hurt either.

Carlsen vs Caruana | Sinquefield Cup (2018)

This is an interesting chess game

Carlsen's secrets: How does he do it?

"There is an equal position on the board, and the opponent thinks: this is dead drawn. I can play almost anything and there is nothing he can do. But Magnus plays on, seeking complications, setting up threats. He is narrowing the margin required to hold the draw. Soon his opponent is thinking: why is he still playing – I can hold a draw with any of these three moves. Then: I can hold with this move and with this move. And then: I still have one clear way to hold a draw. And under the strain of constantly having to solve deep and complex problems, more often than not the opponent will crack. Magnus wins not because it was in the position, he wins because he is Magnus."

Facebook post from 2 years ago.

I have been playing chess seriously for 42 years, so in the 2016 Open Chess Championship when I play an 8 year old who plays almost as well as me, I get nervous. I am also amazed. I was playing 8 year old Luke Ye from Missouri.

There are some gaps in my chess opening knowledge, because chess is nearly infinite, and you can't know everything. Earlier in the week I tried to fix one of my gaps in my knowledge by studying a game played by world champion Magnus Carlsen in the French Defense. When I played the kid, he followed the world champion game closely, which by itself made me nervous, but he also started an attack against my kingside sooner than I expected. I was not quite prepared for this. Before the game I had asked Luke's dad if the kid had coaching, which he had, which means that some master or Grandmaster had taught him to play a certain way against the French Defense. I had the sense that the kid was following some sort of script by wrote, where he had been coached that if you put your pieces on specific squares then you can checkmate your opponent. Around move 15 he started an attack against my kingside and I spent over 20 moves defending. The kid was relentless. He just kept pursuing the idea of checkmating me on the kingside, somewhat to his detriment because it allowed me to be stronger on the queenside. I had my own plan, which took a long time to implement, but my plan was to weaken his pawn structure and trade the pieces down to an even king and rook endgame that was technically winning for me, which is what happened. I had figured that no matter how strong this prodigy might be, he wasn't going to be as strong as me in the endgame.

The two of us had spent spent about 75 minutes each on the first 25 moves. This is about the point that I felt that the game was turning in my favor, so I was able to move more quickly after that.

My opponent's 37nth move was a disaster. When I saw him reach for the pawn I thought "Don't do it!". He played such a good game up to that point, I didn't want to see him throw it all away on one bad move. I was winning anyway, but there was still a little bit of fight left in the game that would have been fun to play out. Instead he made a mistake and the game ended very quickly after that.

It is nice to win a game after a couple of tough losses. I now have 4.5 out of 8. At the very least I will finish the tournament with 4.5 out of 9. I don't think that the last round pairings will be kind to me; I will most likely play someone stronger than me, but I will give it my best effort. It would be very nice to get a draw or a win which would put me over 50%.

Endgame

This is subtle, but I like subtlety.  It is not a very hard position, but initially I had a hard time wrapping my head around why one move is better than the other.   However, it is all about tempos and weak pawns.

How To Learn a Chess Opening. IM Valeri Lilov

I watched this video live. You could make a drinking game, tea in my case, out of every time he says, "This is really important."

Seems to me that the video is light on content, but has a few useful ideas. 

2018-07-01

Instructive endgame

When I played this endgame, I did not understand the subtleties involved.  The computer analysis was telling me that 51. Ke3 was much stronger than the move I made, but at first I had no clue as to why it would have been stronger.  


After diving deeper into this, it became clear that White needed to prevent 51... g5+ and 52.... Kg7 with tempo.  Also, it is easier for White to win this game if he can roll his pawns with f4 and e5, because in some positions the Black king cannot let himself get exposed to Rf8+ and the Black rook is tied down to stopping the b7 pawn.

I don't know if these ideas are common sense or not.  I was playing a speed game and I did not pick up on them.

In the analysis I don't show every possible variation nor do I explain every move, but I do show the above mentioned ideas.

Exceptionally nice result in the USCF Online rated chess.com 3+2 blitz tournament



Before the tournament I said that I was going to "bring it."   I felt like I could do well.

I started the tournament at chess.com rating 1800 and finished with a rating of 1848.


In Round 2 I had a nice victory against our friend Mohamed, who used to come to the Greenwood Chess Club.

Surprise first place finish in the USCF Online rated ICC tournament. (Two weeks in a row.)

Surprise first place finish in the USCF Online rated ICC tournament.  I didn't expect to get first because "Tthius" who was tied with me for first beat the guy who beat me, which was "tigeriz."   However, I won the tournament on tie breaks.

Anyhow, in the following game I felt like I played in a sophisticated manner against an "Over The Board" 2100+ player.  I hope that computer analysis doesn't poke holes in the game, although it probably will.   At one point I offered to give up two rooks for a queen because I thought that I could control some important squares afterwards.  My opponent didn't go for it, but offered to trade major pieces.  Afterwards my plan was to restrict his minor pieces as much as possible.  Eventually he won a piece at the expense of a couple of pawns, but this was apparently a mistake because my extra pawns overwhelmed his king.

The bottom line is that I had a plan, and be it good or bad it worked.  Few of us can have a perfect plan, especially at these rapid time controls, so it is important just to have a plan period.

Black to play and win.

I'm not sure how many people would appreciate the subtlety of this position.  This is from an online game where I got a draw, but analysis shows that Black can slowly make progress until he wins.  It is not possible for me to explore every possible continuation, but I show a couple of lines where Black slowly improves his position until White collapses.  It is actually not that difficult, but hard to figure out in a rapid time control.

Computer comparison of top chess players past and present


I'm a bit surprised by how much lower Paul Morphy is.  In the 1960's Fischer said of Morphy that he was "the greatest genius of us all" and "would beat any player alive today."

It is interesting just how much better Magnus Carlsen is compared to everyone else.

According to a previous study, https://en.wikipedia.org/wiki/Comparison_of_top_chess_players_throughout_history#Moves_played_compared_with_computer_choices, Fischers play during a 3 year period, which I assume was during his peak in 1970 to 1972, was better than any corresponding three year period by any other player, however this study was done before the rise of Magnus Carlsen.

Endgame

The computer agreed with all my endgame moves starting with move 40.  I had a sense that I could out finesse him in this bishop versus knight ending.  Even though his 44... g5? was pretty bad, I still had a superior position.  I am going to to do some analysis to see how the game should go if he doesn't play 44... g5?.
