<<< Who am I ? >>>

I am a graduate student. My current areas are combinatorics and knot theory, particularly finite-type invariants. I'm also a part-time algorithmist, working on image processing, computer vision and data mining.

<<< Anything else besides? >>>

I enjoy hiking and reading. In addition, I'm good at wasting some of the precious time we've been allotted at this valley of tears playing computer games :)

Obviously, I like cats.

I like my humor intelligent, quirky and language-related. For instance, I admire Fry and Laurie and recommend them heartily.

I'm an avid follower of http://xkcd.com, http://www.smbc-comics.com/#comic, http://abstrusegoose.com/ and a few others.

A fancy, nay, an obsession of mine is writing parody songs. One of those, the most chess-related one, can be found further below.

<<< Are you any good ? >>>

My strength varies in the 2050-2100 area. My highest chess achievement is a photo with Vishy Anand (both words are now marked as spelling errors, but then, so is "chessgames.com") back in the 90s when I was a little kid.

<<< Who am I as a chess-player? >>>

In the last few years, my style was heavily biased towards the positional, technical side. I play against pawn-weaknesses, I like rook-endgames and bishop pairs. I try to keep my pawns on the right color, just like they used to do, damn it!

Of late, however, I'm working on becoming more universal and on risk-taking. I have weaknesses in sharp, irrational positions, and would like to employ more varied tools to apply pressure. In particular, I have much to learn about positional sacrifices.

For the rest - read the next section and my page!

<<< Why should you read this page? >>>

Oh no you shouldn't! Really, don't. Go away! You too! AAA they're all around me! ... gulp... yeah, aaaanyway.

Many of the kibitzes focus on a few openings I enjoy analyzing, for now mainly the Larsen variation in the Philidor defense.

I also post analyzed games I deem worthy enough.

<<< Why do I frequent chessgames.com? >>>

There are three main reasons:

The people - <Annie K.>, to name the worst of them :)

The Guess-The-Move feature is, in my eyes, the best
way to improve beyond 1800 I've met online.

Finally, I follow (and sometimes participate in) the chessgames.com challenge. The team, armed with incredible calculating power as well as the ideas of a dozen strong analysts, might well be the strongest chess entity ever.

<<< The promised song >>>

"Black queen" - Pawn must go on

Empty squares - what we are playing for?
Abandoned chairs - I guess we know the score..
On and on!
Does anybody know what piece I知 looking for?

Another bishop - another mindless sac
Behind the pawn-line, in the wild attack
Hold the f-line!
Does anybody want to queen it anymore?

The pawn must go on!
The pawn must go on!
Inside my king is hiding
The tactics may be blinding
But my knight still stays on..

Whatever happens, I値l leave it all to chance
Another Spanish, another failed advance
On and on!
Does anybody know what we are drawing for?
I guess I知 learning
I must be calmer now
I値l soon be playing French and Dragon now
On the board the pawn is crying
But inside the db I知 dying for h3..

The pawn must go on!
The pawn must go on!
Inside my king is hiding
The tactics may be blinding
But my knight still stays on..

My board is painted like the wings of dragonflies
Losing games of yesterday, will draw but never die!
I can play, my friends!

The pawn must go on!
The pawn must go on!
I値l face it with a pin
I知 never giving in
On with the pawn!

I値l play the mill,
I値l overkill!
I have to find the will to carry on!
On with the,
On with the pawn

The pawn must go on

Catfriend: How recent is recent? Most of the results above include events from the last year or two, particularly Topalov's. Of course this doesn't doom Nakamura to struggle against them for eternity, but when the refrain "Naka just has to be more confident against Carlsen and then he'll ...
 
   Apr-05-15 H Lambert vs F Olafsson, 1952
 
Catfriend: Olafsson's 15..Ne8, 16..Nd6, 17..Be6 is rather slow. An immediate 15..a5 16. bxa5 Rxa5 applies sharp pressure on White's Q-side, seizing the initiative. White spent a temp with h3 and created a weakness with b4 - he should be punished for that vigorously!
 
   Apr-05-15 Jacobo Bolbochan vs M Czerniak, 1940
 
Catfriend: After 11..Kh8, White has to work hard to cook up some initiative. 12. Nf3 followed by Nh5 might at least force Black to exchange his DSB for a knight.

Catfriend: The new, rejuvenated, Grischuk must be mentioned. Ding Liren, #14 at 22, is also a promising talent. Yu Yangyi is #30 at 20. As for peaking - Karjakin is 25, MVL is 24 (and has a positive score against Carlsen in the recent years). It might be just a little bit early to write them

  Catfriend: <parisattack> I have plans to publish here a detailed analysis of a few worrisome lines, one of these days :)

I've read the monograph when I was much weaker, maybe it's time to re-read it. In general, though, despite my enormous respect for Larsen, I try to find lines that are good <for me> to play against the kind of opposition <I> am likely to face.

The Maroczy-like clamp is indeed a concern. Personally, though, I feel the hole on d4 gives Black chances.

If you ask me what are my main concerns, I can name four: I. The <positional strangle> - 1. e4 e5 2. Nf3 d6 3. d4 exd4 4. <Qxd4> and then the Maroczy ideas.

II. The <tactical skirmish> - 1. e4 e5 2. Nf3 d6 3. d4 exd4 4. Nxd4 g6 5. Nc3 Bg7 6. Bc4 - White has lots of significant threats and development ideas. Frequently, there are tactical counter-punches, but this line requires good working knowledge and can lead Black to fast demise.

III. The <"main line"> - 1. e4 e5 2. Nf3 d6 3. d4 exd4 4. Nxd4 g6 5. Nc3 Bg7 <6. Be3> Nf6 7. f3 0-0 8. Qd2 d5. Black has lots of ideas, but in practice if White avoids certain traps, he should expect some advantage. Then again, one wouldn't expect a forced equalization by move 8, would they? :)

IV. <Delayed action> - 1. e4 e5 2. Nf3 d6 3. <Bc4> Nc6 and various similar positions: e.g. 4. d4 Bg4 and here 5. d5 and 5. c3. Yet another line, similar in spirit, is <3. Nc3> Nf6 4. Bc4.

Finally, I did think both about Go and about the Game of Life glider pattern when choosing my moniker.

  Catfriend: Meanwhile, I remembered a cool side-line:

1. e4 e5 2. Nf3 d6 3. d4 exd4 4. Nxd4 g6 <5. h4>

I had a regular opponent, very talented (much more than I am, IMO) but without much love for opening disputes. He used this line to take me out of the book and to create immediate struggle. So I had to find a cure.

5..Nf6 turns out to be sufficient.

I'll go over two main alternatives. Before that, I'll mention additional choices:

6. Qe2 Nc6 either transposes into main lines or equalizes.

6. h5 - 6..Nxh5 is possible, of course, but if Black wants to play it safe, 6..c6 7. Nf3 Nxh5 is absolutely fine.

This leaves us with <6. Nc3> and <6. Bg5>.

I'll dispose of the latter first (one can skip straight to 6. Nc3 for hot action!).

6. Bg5 h6 7. Bxf6 Qxf6 8. Nc3 c6 equalizes on the spot.

So we arrive at the main line.

6. Nc3 Bg7

I. <<7. Be2 0-0>>

8. h5 (most principled) d5! Now, 9. h6 Bh8 or 9. e5?! Ne4 are excellent for Black.

So is 9. exd5 Nxd5 10. hxg6 hxg6.
11. Bh6 Bxh6 12. Rxh6 Nxc3 13. bxc3 Qf6 is even better.

Best for White seems 9. hxg6 hxg6 (not fxg6?) 10. 10. Bg5 dxe4 11. Nxe4 Re8 12. f3 Nbd7 but even here, Black can be satisfied with the opening.

II. <<7. Bg5 h6>> We got to the real fun part!
Note that 8. Be3 Nc6 9. Qd2 Ng4 is equal.

White wants more! 8. Bxf6 Qxf6 9. Nd5...
A safe choice is 9..Qd8 10. c3 c6 11. Ne3 h5 (Slightly better for White, playable).

Much better is <9..Qxd4!> 10. Qxd4 Bxd4 11. Nxc7+ Kd8 12. Nxa8 Bxb2 13. Rb1 Bc3+ with good chances. For instance (almost forced), 14. Kd1 b6 15. Bc4 Bb7 16. Bd5 Nc6 17. Nxb6 axb6 18. Rxb6 Kc7

  Catfriend: The following will combine an analysis of a typical Philidor idea with entertaining and continue the "line not taken" series.

A 5/0 unrated against a 2270 opponent on chess.com:

1. Nf3 d6 2. e4 e5 3. d4 exd4 4. Nxd4 g6 5. Nc3 Bg7 6. Be3 Nf6 7. h3 O-O 8. Qd2 d5 9. e5 Nfd7 10. e6 Ne5 11. exf7+ Rxf7 12. Nb3 c6 13. O-O-O a5 14. a4 b5 15. axb5 a4 16. Nc5 a3 17. bxa3 Rxa3 18. Nb1 Ra2 19. Nc3 Ra3 20. Nb3 Qf8 21. bxc6 Rxb3 22. cxb3 Nbxc6 23. Nxd5 Qa3+ 24. Qb2 Nd3+ 0-1

1. Nf3 d6 2. e4 e5 <Getting the Philidor by transposition.> 3. d4 exd4 4. Nxd4 g6 5. Nc3 Bg7 6. Be3 Nf6 7. h3?! <A deviation. Standard here is f3 with same idea, but strengthening the center at the same time and saving tempi for a future pawn-storm. Unfortunately, I didn't consider the differences enough.> O-O 8. Qd2 d5?! <With a pawn on f3, that would be the move. 7. h3 allowed an ad hoc opportunity I didn't investigate: 8..Re8 with significant pressure. One of the best for White is 9. f3 which gives us common lines with White playing the suboptimal h3. > 9. e5 Nfd7 <Safer is 9..Ne4 10. Nxe4 dxe4 with equality.> 10. e6?! <10. f4? c5 is great, of course, and is one of the main ideas in such positions, but 10. Bg5 Qe8 11. 0-0-0 c6 12. f4 poses problems.> Ne5 11. exf7+ Rxf7?! <Safer is 11..Nxf7> 12. Nb3 c6 13. O-O-O a5 <Begins a sharp attack, trying to ourtace the opponent.>14. a4 <Too passive, and allows further aggression. Counter-play with 14. f4 is better.> b5 15. axb5 a4 16. Nc5 a3 17. bxa3 Rxa3 18. Nb1 Ra2 <Black has quite a few threats by now. Bf5 will target c2, Nc4! looms large.> 19. Nc3? <Allows a powerful tactical solution.> Ra3? <Misses it! I was ahead on time, and wasn't against what seemed a move repetition, to gain a few seconds. However, this allows White to improve his defence. Winning was 19..Nf3!! Now losing material with 20. Nxa2 Nxd2 is the lesser evil. 20. gxf3 Qa5!; 20.Qd3 Ra1+ 21. Kb2 Bxc3+ 22. Qxc3 Rxd1; 20. Qe2 Qa5 all win.> 20. Nb3 Qf8 <Setting up a trap.> 21. bxc6 Rxb3!? 22. cxb3 Nbxc6 23. Nxd5?? <Allows a winning check. 23. f4 would continue the sharp struggle and is hard to evaluate. An interesting line is 23. f4 Qb4!? 24. fxe5 Bxe5 25. Re1 Bxc3 26. Qxd5 Kg7! and Black seems to be winning.> Qa3+ 24. Qb2 Nd3+ 0-1

Nc3 Nc6 <Provocative. I usually opt for the slightly neater 8..Nbd7. The game move tempts White to take on c6. The pawn structure after 9. Nxc6 bxc6, however, isn't weak at all. 10. 0-0 Nd7 11. Qd2 Nb6, then Qf6 and Be6, and it's not at all clear who's better.> 9. O-O Re8 <I suppose 9..Ne5 is objectively better.> 10. Bf2 Nd7 <Here as well, 10..Ne5 is great.

Nxb7! and Black can't take - 35..Rxb7?? 36. Rxb7 Nxb7 37. a6! 1-0 Of course, 35..Ne4 and Nc5 is still better for Black, but the result is far less obvious this way. Now it's a matter of technique.> bxa6 36. Nxa6 Rxb8 37. Nxb8 c5 38. Kf2 Ke6 39. Ke3 Kd5 40. Nd7 h5 41. h4 c4 42. Nf6+ Kc5 43. g3 Nf5+ 44. Kf4 c3 45. Ne4+ Kd4 46. Nxc3 Kxc3 47. g4 hxg4 48.

Kg4 f5+ 0-1

I note with pleasure that after 4..g6, only three moves (13..Qf6, 23..c6, 33..Rxb2) weren't among the best alternatives, and that ~40 were the strongest possible or equal.

  Catfriend: A victory against a CM is always nice. It was not a perfect game (3/0 after all...), but some of the harder decisions I made were surprisingly correct. Also be sure to notice the comments to move 33.

1. e4 c6 2. d4 d5 3. exd5 cxd5 4. Bd3 Nf6 5. h3 Nc6 6. c3 g6 7. Nf3 Bg7 8. O-O O-O 9. Bf4 Bf5 10. Re1 Bxd3 11. Qxd3 e6 12. Nbd2 Rc8 13. Ne5 Nxe5 14. dxe5 Nd7 15. Nf3 Qc7 16. Qe3 Qc5 17. Qd2 Nb6 18. Bh6 Qe7 19. Bxg7 Kxg7 20. Qf4 Rc4 21. Nd4 Rfc8 22. Re3 Nd7 23. Rae1 a6 24. h4 b5 25. h5 b4 26. hxg6 hxg6 27. Rh3 Rh8 28. Rxh8 Kxh8 29. Qh6+ Kg8 30. Re3 Qf8 31. Qg5 bxc3 32. bxc3 Nc5 33. Rh3 Nb7 34. Nxe6 fxe6 35. Qxg6+ Qg7 36. Qe8+ Qf8 37. Rg3+ 1-0

1. e4 c6 2. d4 d5 3. exd5 cxd5 4. Bd3 <Fischer's idea. White intends to take hold of e5, while preventing Bc8 from getting to a good square.> Nf6 5. h3 Nc6 6. c3 g6! <One of the two best replies. The other is 6..e5 7. dxe5 Nxe5. After 8. Nf3 Nxd3+ 9. Qxd3 White must play with decision against the isolated d5, as the endgame might see the bishop pair triumphing.> 7. Nf3 Bg7 8. O-O O-O 9. Bf4 Bf5!? <Designed to counter White's intentions about this bishop. If White takes, he's objectively better but it's very hard to prove in practice.> 10. Re1 Bxd3 11. Qxd3 e6 12. Nbd2 Rc8 13. Ne5?! <A dubious move "by inertia". This idea is central in the exchange variation. However, after the bishop exchange, it lacks the usual punch. Better was 13. Qb5. > Nxe5 14. dxe5 <Aggressive. 14. Bxe5 admits White didn't get much out of the opening. Probably true, but lacks spirit!> Nd7 15. Nf3 Qc7 16. Qe3 Qc5 17. Qd2 Nb6 18. Bh6 Qe7 19. Bxg7 Kxg7 20. Qf4 Rc4 21. Nd4! <A most advance, but this knight will serve faithfully till the end. It also frees the 3d line for Rook maneuvres a la Karpov.> Rfc8 22. Re3 Nd7 23. Rae1 a6 24. h4! <Introduces new threats. Black has a well-defined strategy on the Q-side, and must be troubled before he completes it.> b5?! <A bit too slow. If that was the intention, 24..b5 should be played directly. At this point, h5 is an issue and should be prevented via 24..h5 despite creating other weaknesses,> 25. h5 b4?! <Now caution is in order: 25..Nf8. > 26. hxg6 hxg6 27. Rh3! <Gains clear advantage.> Rh8 28. Rxh8 Kxh8 29. Qh6+? <The one bad move by White. This gives Black an opportunity to escape. 29. Re3 would be a much preferable move order.> Kg8 30. Re3 Qf8 31. Qg5 bxc3 32. bxc3 Nc5?? <A losing mistake. 32..Qg7 would be a more tenacious defence.> 33. Rh3 Nb7?! <Fails to find a possible complication. Black had 33..Rxc3!? 34. Rxc3 Ne4. Now the natural 35. Qe3 Nxc3 36. Qxc3 is winning, of course, but technique is still required. Best for White is 35. Nxe6! Qe8! 36. Nc7! Where can the Queen go? 36..Qd7 37. e6! Qd6 38. exf7 Kxf7 39. Rf3+ 1-0; 36..Qc8 37. Nxd5; 36..Qb8 37. Nxa6 (still attacking the poor Dame!) Qf8 38. Qc1 reaching a most pleasant edition of the previous endgame. Black might as well just play 36..Qf8 and reach it with a6 alive.)> 34. Nxe6! <The natural, "orderly" finale for the game, exploiting the previous motives: control in the center an excellent knight on d4, a strong rook, passive Black pieces, the g6 pawn weakened by h4-h5-hxg6.> fxe6 <Now the game is over, but there was no defence.> 35. Qxg6+ Qg7 36. Qe8+ Qf8 37. Rg3+ 1-0

As usual, the best lines are in the commented shadows.

  Catfriend: A counter-Maroczy Philidor against a 2000+ opponent featuring a typical strategy - as well as a typical oversight :)

1. d4 d6 2. e4 e5 3. Nf3 exd4 4. Nxd4 g6 5. Be3 Bg7 6. c4 Nf6 7. Nc3 O-O 8. f3 Nc6 9. Qd2 Re8 10. O-O-O a5 11. Nxc6 bxc6 12. c5 d5 13. Bg5 Qe7 14. exd5 cxd5 15. Nxd5 Qxc5+ 16. Qc2 Qxc2+ 17. Kxc2 Bf5+ 18. Kc1 Nxd5 19. Rxd5 Rab8 20. Rb5 Re1+ 21. Kd2 Rxb5 22. Kxe1 Rxb2 0-1

1. d4 d6 2. e4 e5 3. Nf3 <Getting into Philidor. 3. dxe5 dxe5 4. Qxd8+ Kxd8 is a whole new story.> exd4 4. Nxd4 g6 5. Be3 Bg7 6. c4 <Aiming for Maroczy-like structure, preventing d5. White hopes to increase the pressure in the center, combining space advantage (d5, f4-f5 pushes etc.) with standard Bh6-h4-h5 plans.> Nf6 7. Nc3?! O-O?! <The great weakness of automatic replies is that they miss ad-hoc opportunities. 7..Ng4 and Black's already better. > 8. f3 Nc6 <8..a6 and 8..Qe7 are also good alternatives. Nc6 is very thematic in these position. Black doesn't fear the weakened pawn-structure - he welcomes it! the c6 pawn prevents Nd5 and allows future d5 breakthroughs. In addition, the b file and the pressure on d4 will be handy. > 9. Qd2 Re8 10. O-O-O a5 <Here and a move before Nxd4 and Be6 is a viable option, but I feel it limits Black's resources.> 11. Nxc6? bxc6 <Black will now play for the win.> 12. c5 d5 <Note that in case of exchanges on d5, Be3 is left hanging - a frequent consequence of f3-Be3.> 13. Bg5?! <A natural move, given the previous comment, but it allows a powerful reply.> Qe7! 14. exd5 cxd5? <Black's turn to err. The intention was to fortify d5 with c6, consolidate, and only then move to attack. 14..Qxc5 with Rb8, a4, Bf5 and so on would be crushing.> 15. Nxd5 Qxc5+ 16. Qc2?? <The final big mistake. After 16. Qc3 Black's advantage would be dubious at best.> Qxc2+ 17. Kxc2 Bf5+! <Achieving harmony between the pieces. White is also being tempted into 18. Bd3? Nxd5 19. Bxf5 Nb4+> 18. Kc1 Nxd5 19. Rxd5 Rab8?! <19..Re1+ 20. Kd2 Rb1 would be even more decisive.> 20. Rb5?! <b3 would be better.> Re1+ 21. Kd2 Rxb5 22. Kxe1 Rxb2 0-1 <The resignation isn't premature: Black is up a rook, de facto, and will soon gobble up an additional pawn or two.>

Then again, if we're spilling dirty secrets, she told me, and I quote, you have "an incredible mind and erudition".

And I actually mentioned the referred-to linguistic mistake to my group, because one can't resist these temptations to show off, can one? ;)
