The Cherry Blossom Classic, Part Two [EvolutionBlog]


After my win in round two I was excited for round three. My opponent sported a 1952 rating, and he had white. He opened with 1. e4.

Now, over the years I’ve tried most of the major defenses to e4. I was an aficionado of the Dragon Sicilian for a while, until I noticed I kept getting mated on h7 against stronger opponents. Then it was the Scandinavian for many years. I had many good games with it, but eventually I lost confidence. If white knows what he’s doing he can make things pretty unpleasant for black.

So I’ve recently turned to the open games. This is not a move (ha!) to be taken lightly. Openings with 1. e4 e5 are the ones we all learn when we first start playing this miserable game. But it turns out that this simple, common sense beginning leads to some of the most intense tactics in all of chess. The King’s Gambit alone can drive you insane. Not to mention the Goring and Evans Gambits. Heck, a lot of the time white can just sac his king’s knight and get a reasonable position for his trouble. And that’s before you even start studying the more reputable lines. Black can get mated pretty fast if he’s not careful. I’ve devoted some time to studying the relevant lines, but I still find them pretty hairy.

The good news is, my opponent did not test me in any of those lines. The bad news is that he chose the Scotch Game instead. The Scotch is to e4 e5 what the exchange queen’s gambit is to d4 d5 openings. Boring!

Here’s the position with black about to make his eighth move:



This is the Mieses (pronounced MEE-sis) variation. Black now has to choose between moving the attacked knight with Nb6, or pinning the c-pawn with Ba6. In his book on the open games, Marin recommends Ba6. But Bologan, in his book, prefers Nb6. The computer says they’re both fine.

I chose 8. … Nb6. After the game my opponent told me he was annoyed by this, since he knw much more about the Ba6 lines. Whoo hoo!

Alas, it was mostly a pretty dull game. Skipping ahead, we have black about to make his fourteenth move.



Time for a pawn break. Black’s got three of them to choose from: d6, d5, or f6. I chose 14. … f6. The computer thinks this is fine, but prefers both d6 and d5. Drat!

But really, for the rest of the game nothing much happens. The computer felt I had a small edge through most of it, but it doesn’t point to anything dramatic that I missed. I could probably have put a bit more pressure on white than I did, but all in all it was one of my better analytical efforts.

White, for his part, also played with little ambition. The pieces came off the board pretty quickly. Here’s the final position, after thirty-two moves:



Draw agreed. The computer’s evaluation is 0.00.

So, after three rounds things were going OK. Rating-wise I was up about three points. The win in the second round canceled out the draw to the lower-rated player in the first. I had just played two respectable games in a row, so I was feeling good about Round Four, the Sunday morning game.

My opponent turned out to be another kid who was eye-level with the pieces. This one was sporting a rating in the 1400s, however. He was playing way up. In Round Three he beat someone higher-rated than me.

Well that’s just peachy! Some grossly underrated kid. A win would get me basically nothing in terms of rating points, while even a draw would mean a huge hit.

Whatever.

I had white this time. I opened with e4, and he responded with the French Defense. The Advance variation has been my main reply to the French for a while, but I’m losing confidence in it. Here’s the position with white about to play his twelfth move.



For a long time, the Advance variation was considered inferior to Nc3 or Nd2 for white on the third move. It’s modern revival had much to do with the work of GM Evgeny Sveshnikov, whose creativity in the opening is well-known. (Just look at the crazy line of the Sicilian that bears his name.) When he plays the Advance, he usually ends up mauling black’s kingside in a blaze of tactical glory.

When I play it I just seem to end up with a weak d-pawn with little to show for it.

But seriously, 1400-rated kids now know French Defense theory ten moves deep? What the frick? When I was 1400-rated I barely knew what the French Defense was. This kid was blitzing off good moves and was looking bored doing it.

Sometimes, chess blows.

OK Rosenhouse, get your head in the game. Is this kid going to get the better of you? I don’t think so! Book smarts only get you so far. You may have memorized a few moves my youthful opponent, but I have life experience.

By which I mean, I know a few things about the endgame. Or at least I thought I did, before this game. (Oops. Spoiler.)

Here’s the position, with white about to play his thirty-third move.



The position has changed a bit. White has a healthy, mobile pawn majority on the queenside. But he is also facing a protected, passed d-pawn, and he has to do something about his bad bishop. Objectively, the position is dead level. But I was feeling good, since black really can only sit and wait, while white can make some mischief.

I pushed my kingside pawns, in an attempt to give him something to worry about. That led to this position, with black about to play his thirty-eighth move.



My little kingside demonstration provoked 38. … g6. I got excited, since this creates a weakness on h6 for my bishop to aim at. I thought I might already be close to winning now, but the computer explains that the position is still level. When I move my pawn to h5 to fix the weakness, black gains the plan of transferring his knight to f5 via c6 and e7, leaving his king to defend the queenside.

But black didn’t play this plan. Instead we reached this position, with white to play his forty-second move.



Folks, explain to me please what kind of fish doesn’t play f5 and f6 here? I saw it immediately, of course. The first point is that black cannot take with exf5. That would leave black’s d-pawn defenseless, after which white would just march his king right into black’s position.

But what then? He would have to move his king over to cover the h-pawn. Pushing the pawn to f6 then locks the kingside, and forces black to just leave his king in the corner. With a little preparation, I then play the clearance sacrifice with b5. Black will temporarily be up a pawn, but then the white king will just march into the queenside. In the close-quarter fighting, the knight is no match for the king.

And I saw all of this. But somehow I decided that things weren’t so clear after the pawn sac. I kept finding silly lines where the knight jumps around like it’s on a pogo stick, making trouble. And I thought I had an even simpler winning plan. I would just maneuver my bishop all the way to b6 and flush out the knight that way. Then I can play b5 without it being a pawn sac and just win prosaically.

Sadly, it’s all crap. The b5 sac wins trivially. And the Bh4-d8-b6 plan doesn’t work, since Nc6 will then gain a tempo for black by attacking the bishop, after which pushing the d-pawn can be a very effective decoy.

So I missed my opportunity and futzed around for a few moves, looking for the obvious win I was certain had to be there. Eventually my opponent played 48. … f5:



The position is just completely blocked and white cannot make progress. I made him shuffle the pieces around for another twenty moves, but white’s moment has passed. Draw agreed.

Chess suuuuuucks. (I know, I know. I suck, not the game. You’re really going to bring that up now?)

That little draw cost me sixteen rating points. Oh well.

Now, round five was Sunday night, but when registering for the tournament I decided to take a bye. I wanted to have a day to spend in Washington DC, where there all sorts of fun things to do. I had dinner at a good Indian restaurant in Georgetown, and then went over to the E-Street Cinema. They show independent films and documentaries. I saw The Man Who Knew Infinity. The film is about the true story of the relationship between British mathematician G. H. Hardy and Indian prodigy Srinivasa Ramanujan. Jeremy Irons and Dev Patel played the leads. (Short review: Good, but not great. Needed more math.)

Going into the city was a good idea. I needed some time to shrug off my disappointment in round four.

That brings us to Monday, the final day of the tournament. Now, I had already decided to skip the last round. It was a two-drive home, after all, and I needed to get ready for class the next day. And once you check out of the hotel it’s awful to have to sit around the lobby for hours waiting for the round to start.

That meant I only had one more game to play, on Monday morning. It turned out to be a doozy! Stay tuned!
