French, Exchange – positional war

I played yesterday in the club,  regular G/90.  Here is the game.

It was one of 3 guys I expected  (Swiss+possible byes).

I knew that as White after 1. e4 e5 he doesn’t play my favorite Ruy, rather Four knights or Italian which I don’t like.

So I decided to go with French. It became Exchange variation, which is not my style and I think it showed. I got under pressure on “e” and had to watch over “e6″ square all the time.  It really remainded  me a positional war like World War I with soldiers mostly remaining in trenches and exchanging fire.

He tried to attack on kingside, but I halted his “h” pawn.

Then I realized that I am intercepting the initiative.

He had 5-10 minutes less than me, about 25-30 minutes, got a bit nervous and started to repeate the moves. I spent some time improving the position of my knights and we got equal,  15 minutes each. I saw the move 39… Ne4+, by the way Fritz wanted Ne4+ on move 33 and 35,  and that I get passed pawn after exchange, but having difficulty fully evaluate the position, with only 15 minutes for arising complications and feeling somewhat tired after long previous defense I offered a draw (even forgot that I should make a move). He agreed, of course.  Fritz at home offered instead of 39…Ne4+ – 39… Qe8 40. Kg1 Ne4 and evaluated line after that as ~-0.75.  I didn’t see Qe8 anyway.

Maybe I’ll run shootout between Crafty and Fritz to see what could be the result.

 

Opening catastrophe

It was a first round of the Swiss tournament. I played with the same master, as last time. Here is the game. He was much more attentive this time and in the opening I was on his territory, he played his favorite French ( I play it too, but our experiences probably are not comparable). I played Tarrasch variation and it was line I am less familiar with, just once played blitz. I know there is a sharp move 10. Nf4 here, but I thought White is better when the pawns are not exchanged, wasn’t sure about this case. After some thinking I decided not to go into complications, just play safe exf6. My knowing of this line ended right after that. His Qb6 was delaying my queenside development, so I decided to do something.

I thought about b3 (12. b3 O-O 13. Bf4 – 2nd DB choice), but then decided that a3/b4 (5th choice) is better. His e5 was unexpected, I forgot that I played it myself, it was quite some time ago, in short words – I was rusty in the opening.

Calculating exchange on e5 I thought about Bxh7 afterwards, but because h6 is under control I saw that there is nothing there. After Bxe5 I played Rb1 and sudden Ng4 was pretty shocking. I thought that Be3 was losing only pawn, but it was losing more …

The same Be3, just one move before – 16. Be3 was leading to an equal position.

Funny that it was all theory, all this losing line, it was played before. I was very upset for a couple of days, but life goes on …

 

A bit of tactics

Here is a position from one of my correspondence games:

White to move,  win.  Just in case, the answer in in the comment.

 

Last round

Yesterday I played in the last round of the Swiss tournament going on in my club.

I was pretty high in standings,  so got a master. I played with him about a year and

a half ago. He was White, played English opening and strangled me in 30 moves,

finally I was in complete zugzwang and resigned.

It was a different game now.  I lost in 40 moves but put up a good fight before

blundering under pressure on move 32.  Here you can see the game.

I was White and it was Sicilian, Moscow variation – 1. e4 c5 2. Nf3 d6 3. Bb5 .

He played 3. … Nc6,  I never had it before, usually it was Bd7. I transformed it into Rossolimo variation by Bxc6. He started to press me on the queenside, then played f5. It was played twice before against me with no positional ground, I won both games. Here it was sound. Soon he moved all his kingside pawns, I got counter-play in the

center. I won a pawn, he got attack, Fritz considered it equal. Then feeling strong pressure I thought about relieving it by sacrificing exchange for the pawn in the center (Fritz absolutely didn’t like this idea,  giving -2.70 evalution after 5 moves). By the way, Fritz  didn’t see any reason to panic and evaluated the continuation without sac as equal – -0.30. But I am not Fritz …

After spending quite some time,  I decided to give that sac up and instead,  quickly played general defending move by the queen. Time was pressing, we had about 30 minutes left and it was intense middlegame. He moved g3 right away and to my horror I realized that my knight has nowhere to move.  After losing the knight the position started to deteriorate.  He sacrificed the bishop on g4,  I couldn’t take it because of check on “h” and mate on diagonal a7-g1.  Then he sacked the bishop again on h3 and it was over.

I still feel upset, the result wasn’t surprise for me,  of course,  but maybe I could do better.  Anyway, the tournament was good, I got 4.5/8 and ~2100 performance rating

which hopefully will raise my rating over 1800.

 

Running up the ladder

Running up the ladder

Yesterday I played with an expert and won. It was a 16 year old boy.

I thought he is rated 1900+ until I came home and found out that after the last big tournament

he got 2001 rating. After I learned about my opponent I got nervous, first because I thought it’s the guy to whom I lost a year ago in Sicilian, Moscow variation.

He effectively finished me off, first with a pawn, then with queen sacrifice.

It wasn’t him (it was his brother), nevertheless I was still nervous since there was that feeling that my lucky streak (+1,=2) should somehow end.

OK, so I am White, Sicilian, my favorite Rossolimo –  1. e4 c5 2. Nf3 Nc6 3. Bb5.

Here is the game. I decided to counter his f5/f4 with d4 and got a pretty good position.

Recent reading of an excellent “Predator on the Chessboard” book on www.chesstactics.org

affected my play in this game. As soon as he played Ba6 I told to myself – this piece is loose.

I could actually win a pawn right away, didn’t see it. Later I also noticed that his back-rank is weak, Ne5 is threatening with dangerous Nf7+, etc. So, these tactical motives were kind

of on the backgound. I still missed a few chances to win a pawn related to Qb3+.

Anyway, his 27. … Nc1 was a mistake and 29. Ra3 finally used that looseness of Ba6, giving me advantage. I missed winning a piece after 30…. Ne2+ 31. Kf1. Trying to counter-attack he didn’t play good moves, his position deteriorated, then he blundered under pressure.

He resigned after double-check 36. Ng6++, it was a mate in 2 – 37. Qh8+ Kf7 38. Ne5#.

So, I got revenge an mafia style, good.

I am going to update my DB of missed tactics with few “gems” from this game and

definitely will return to that tactics.org site. This is definitely the way to go.

I still missed a few chances related to Qb3+ to win a pawn .  Anyway, his 27. … Nc1 was a mistake and 29. Ra3  (Fritz’s choice)  finally used that looseness of Ba6, giving me an advantage.  He thought for about 15 minutes,  it erased his advantage in time,  still couldn’t find a good answer, not that there was one.  My nervousness at this moment disappeared,  I realized that I can win. I took on e5 with the knight, thinking that I don’t want to play the endgame.  Fritz would prefer to win an “a” pawn,  but again I wanted to use my chances in the middlegame,  having a bit more than 30 minutes left.

I missed winning a piece after 30…. Ne2+ 31. Kf1. Trying to counter-attack he didn’t play good moves, his position deteriorated, and he blundered under pressure.  He resigned after double-check 36. Ng6++, it was a mate in 2 – 37. Qh8+ Kf7 38. Ne5#.

Going up the ladder

Yesterday I drew with an expert. It was a guy 25-27 years old.

I was Black, he started d4 and it became Benoni without d5 – 1. d4 Nf6 2. c4 c5 3. e3.

My first 7 moves were intuitive, still very good, then somehow delayed development of my queenside got me under pressure. I played 14. … Qb6 instead of Qc7 and after 15. Rb5 Qc7 16. Be7 lost an exchange. It looked like familiar scenario with much higher rated players – getting positionally overplayed, then missing a tactical blow. There were, however, 2 big differences.

First, I had 2 strong bishops, no weaknesses and thought that the position is defensible.

Second – his clock. He spent about half of his time on the first 15-16 moves (it was G/90), I spent ~30 minutes. I thought it will be a factor. Both my suggestions were right.

I missed winning exchange just after a few moves (try to find it). Eventually after 24 moves I got my exchange back, trapping his rook with my 2 bishops. I could play Nxd5, but was afraid of the pin. As the guy rightly pointed after the game I had Nf4 avoiding it. So I played Qxd5 and had to give up the pawn on g6. He was thinking a lot on every move getting in real time trouble. I decided to keep tension on the board, do not exchange queens and see what happens. Soon I made a wrong move allowing him to win an exchange with decisive advantage, but he didn’t notice it. After 35 moves he had I think less than 5 minutes, I had 20-25. Then it became 2 minutes, he started to play faster. When he had about 30 seconds on the clock ( I had ~10 minutes) he made a move forcing me to exchange queens. After the exchange we got an opposite colored bishops endgame, him up a pawn. Suddenly I felt like blown air balloon, I realized I don’t want to win on time this drawn endgame. I offered him a draw, he agreed, of course. The guy was very nice and friendly before the game, I felt like he didn’t deserve to lose and I to win (I didn’t actually show GM’s 2550 performance in this game).

I will post Fritz annotations later, as always Fritz spoiled my eyphoria .

Also, there is an interesting FIDE rule:

Article 10: Quickplay Finish

10.1 A `quickplay finish` is the last phase of a game, when all the (remaining) moves must be made in a limited time.

10.2 If the player, having the move, has less than two minutes left on his clock, he may claim a draw before his flag falls. He shall stop the clocks and summon the arbiter.

If the arbiter agrees the opponent is making no effort to win the game by normal means, or that it is not possible to win by normal means, then he shall declare the game drawn. Otherwise he shall postpone his decision or reject the claim.

Would be just moving the pieces and advancing the pawns in this endgame  ( I can’t win of course) qualify as “making no effort to win the game by normal means”?  What do you think about that?

I posted the game, raw pgn. I will post Fritz annotations later.

Here is the game annotated by Fritz.

 

I’ll take the point

I played yesterday in my new club, G/90. I am not satisfied with my play,

I think I wasn’t fully concentrated, also my chronic undercalculating.

Anyway, the result was good – I won.

It was another +100 rated guy, it’s like I am playing in U2000 tournament.

I was White and it was Ruy Lopez, Classical variation, 3. … Bc5.

I never played against this variation OTB, a few correspondence games that I don’t remember.

It showed, as I missed winning a piece at the very early stage and got under some pressure later.

At one moment, I made a wrong move, allowing my opponent to win an exchange, but he missed it.

Than we got a position, where I deliberately allowed his rook on the 1st line (following queens exchange)

to relieve the pressure on “d” line. It actually brought me even bigger dividends,

as we exchanged both rooks and went into the knight endgame, where I clearly had better perspectives.

I played pretty well this part, except made a stupid mistake losing a pawn, which he didn’t notice.

My “a” and “b” passed pawns decided the game, sacrificing themselves but distracting Black’s knight and king.

I’ll let you to find the tactics, consider it like a tactics exercise.

I will post Fritz annotations later, Fritz had his day on this one .

Change of decorations

Yesterday I started in a new chess club.

People, who read my posts and comments, know the reason.

The old club was good, but I grew up and higher rated people stopped to come.

I got into Open section (there was also U1700), down three quarters of the rating list.

My opponent was very old guy, rated 100 higher.

I was Black, he started with Nf3. I was almost ready to play Grunfeld, but then seeng d4 and c4

suddenly decided to transform to Benko. I saw that the guy likes positional play and

didn’t want to compete with him on that ground.

He didn’t accept the pawn, eventually I got some initiative.

My position on the queenside looked good and I managed to create a weak pawn – b2.

Then he forced exchange of the rooks pair and queens.

His sudden exchange on f6 took me by surprise and his pawns attack in the center

required some measures from me. After that I didn’t see how I can strengthen my position

and forced rooks exchange, after which opposite-colored bishops made the result clear.

He offered a draw, I agreed.

I thought that I played pretty well, Fritz at home as always spoiled my euphoria.

It found that I missed a nice little tactics at the very end – 28… dxe5 29. fxe5 Bc3 30. Rd1 Bxe5

winning a pawn, though winning this endgame won’t be easy (if possible at all).

I made the same mistake as I did in the previous Benko game (“No pain, no gain” post).

I didn’t think about the line I didn’t like.

Why would I give him strong pawns in the center after dxe5 fxe5 – to  create a passed pawn?

But if would see that his back rank is weak then these pawns would look differently.

Rook vs. Knight

I recently played a blitz game, where for the first time ever I got this ending. I had pretty remote idea how to win, pursued his knight (ignoring the draw offer) for 48 moves until he blundered.  Of course I wasn’t quite satisfied, so I decided to learn this ending.

Dvoretsky says that it is usually drawn, but there are several exceptions:

1. If the knight separated from the king, often it can be caught.

2. If the knight is in the corner, it can be taken because of zugzwang.

3. The squares g7/b7 are not good for the knight.

So, I looked at my game and found the moment (mostly my opponent played right),

where I could separate and win his knight. It is not easy and even Fritz had a problem,

so I used Endgame Nalimov Tablebases Online. Here is the result:

What I also learned that there are typical ways of attacking/restricting the knight,

for example putting the rook nearby on the same vertical/horisontal.

Though this ending is rare, I found it useful for learning about

relative strength/interacting of the rook and knight, which should be useful

for the regular endgame (with pawns).

6. … Kd8 7. Kd4 Nc2+ 8. Ke5 Na3 9. Rb7

9. … Nc4+ 10. Ke6 Kc8 11. Rb5 Ne3 12. Rb2

12. … Ng4 13. Rc2+ Kb7 14. Re2 Ka6 15. Kf7

15. … Nh6+ 16. Kg6 Ng8 17. Re8 Nh6

Though this ending is rare, it shows very well the relative strength of the rook and knight.  Also you can learn the typical ways of attacking/restricting the knight, for example putting the rook nearby on the same vertical/horisontal which should be useful for the regular R vs. N endgame  (with pawns).

 

Mate in 8

I was playing blitz yesterday and got a position, where I delivered mate in 3 moves. Afterwards I ran the game through Fritz and Fritz said that my opponent didn’t chose the best continuation ( I knew that) , anyway there was a mate in 8  ( I didn’t know that). I found it interesting and made a calculation training exercise out of it.  I almost solved it, it was a wrong order of moves on the end. I offer you to try it, the answer is in the first comment. White to move:
