Surprise 3rd place tie.

I had an interesting and lucky win against Blues4 in a top heavy chess.com USCF Online rated speed tournament with at least a couple of masters.  I went from 1872 to 1902, breaking 1900 which seems very hard to do on chess.com.  Not sure if rating points are easier to get now, but I am about a hundred points higher than I was a few weeks ago.

A couple of my games were too easy where I won quickly.  Against higher rated players I choked in a couple of games making blunders. The remaining 3 games were intense battles that I won.

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.

Eric Schiller Dies at 63: "Will be Remembered for His Love of Chess" - US Chess



I met this guy at the National Open around nine years ago.  Compared to other professionals he was extremely nice.  He briefly looked at one of my games and recommended a chess book.

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.
