My analysis of Tin - Hakimifard, Baku 2016 - A tremendous fighting game from our very young debutant.

For a change, I've decided to analyse a game between Tin Ruiqi, (Jingyao's younger sister) and the Iranian board 3, Hakimifard. Even though Ruiqi was outrated by over 400 points, she put up a great fight and was very close to holding her opponent to a very creditable draw. Unfortunately, after over 6 hours and 125 moves, she went down in flames. Still the game is quite instructive and I should mention that the Iranian coach was very impressed with Ruiqi's fighting spirit.

Ben and I were following the game live in our hotel room and we were initially not able to achieve point 3. However, it is now quite clear that Black can place the White king in a series of small zugzwangs and then it is only a matter of time before the rook is forced to leave the a5 square.

Analysis of Utegaliyev - Goh from the Baku Olympiad - Life is tough!

***Addendum: The Rook & Bishop vs Rook ending at move 102 was covered specifically by Karsen Muller & Frank Lamprecht on page 301 of Fundamental Chess Endings. My annotations are slightly confusing there. What I meant to say was that in that specific position, the guiding principle is that the White king should stay on e1 and the rook should be ready to block on f1 whenever possible.

And so after 3 tournaments in Europe, I am back home and back to work. It was of course disappointing that I had failed to make my final GM norm but there were also some positives, the most important of which is that I am a lot wiser now and I think I know what to work on moving forward in order to fix the gaping holes in my chess knowledge. I will also have my highest rating to date although in all fairness, 2457 at the age of 33 is hardly impressive and is certainly nothing to shout about.  The truth is that when I'm on a fine streak, making a norm is entirely within the realms of possibility but I lack sufficient knowledge in certain types of position and I did not have the ability to react in unfamilar and strategically or tactically complex games.

In this and the next few posts, I will analyse the games which I felt to be most instructive. Which probably means there will be very few wins since I only have 1 really good result which most who followed the Olympiad might know by now.

The most painful game by far was probably the game against Utegaliyev, a 2513 untitled player from Kazakhstan. Just to provide some context - I had lost my previous game against a 2500 GM from Estonia and it was important for me to bounce back as fast as I could.

The game began well and I managed to outplay my opponent from the opening and was clearly better, if not winning, and blundered in time trouble at a critical juncture. After a topsy turvy middle game where my opponent somehow managed to hang on with very little time left, we reached a bishop and rook vs rook ending and the conclusion to the game was just, well, epic....

After the game, I was completely exhausted but while waiting for the bus to bring me back to the hotel, I suddenly had an epiphany of some sort. Of course, I had seen a particular game (live!) 8 years ago at the Dresden Olympiad and marvelled at the technique that Black demonstrated in that game:

A game that I liked (ChessBase 13)

Yep, chess is a really cruel, cruel game....
