4. e3 Bf5 5. Bd3 Bxd3 6. Nxd3 Bg7 7. Ne5 Qc8 {Nd7 right away was easier, kicking out the e5-knight.}

32. b3 Ke6 33. a5 Rc6 {Rb5 is much better I think, when it should be a draw. Notice then black can’t really make progress as if the king goes too far forward, then e6! wins.}

25… Nde4 {and in black storms, a loss of material is inevitable.}

26. Nxe4 Nxe4 27. Bxe4 {If the queen moves then just Bxd3 and Qd2 and white’s pawns fall quickly.}

27… Bxf1 28. Rb1 {more or less equivalent to the alternatives.}

28… Qxc3 29. Bxd5 exd5 30. Rxf1 cxd4 {yea, this is over. So, earlier white should have probably have traded the light-squared bishops to avert some of the pressure. The structure that came about is very static, but in some lines, white can be quite justified in going g4! With king-side pressure. }

An interview with Aaron Grabinsky (NM)

chess959: I would like start with a very tricky question:

grabinsky

Aaron Grabinsky: Sure.

 

 

 

 

 

 

chess959: Which one is a chess variant: Chess960 or SP#518 (RNBQKBNR)?

Aaron Grabinsky: SP#518? though not exactly sure. What exactly is SP#518?

chess959: The chess we already knew: Rooks at the corner…

Aaron Grabinsky: oh, lol, then no, chess960 right? yea, chess960 would be the variant

chess959: Just think about it for a moment.

Aaron Grabinsky: Okay :) I guess in a funny way, SP#518 would actually be the variant.. huh, never thought about it that way.

chess959: We now know that some people intentionally misdescribe chess960 as a chess variant. What could be the main reason for this?

Aaron Grabinsky: Maybe because chess960 isn’t as popular as SP#518? that would be my guess, so people assume it’s the variant.

chess959: That’s the point. People assume it a chess variant. But it is not. Chess960 is a generalization of chess. If Chess960 were a variant of chess, then chess could not be a position within the variant. But it is! Chess960 encompasses chess. We have a chess centric point of view I think.

Aaron Grabinsky: yes :) chess 959 doesn’t include normal right?

chess959: Yes, chess959 means no more SP518

Aaron Grabinsky: yea, well that makes sense, about the variants, I mean,,, which is which

chess959: Carry out this simple thought experiment that questions our Chess centric way of thinking: “In an alternative reality, hundreds of years ago the game of  Chess960 was invented. Then late in the 21st century, a small movement began to only play SP518 (Chess). But players all around the world asked the simple question, why would you want to dumb down Chess960 like that?”

AND Chess (SP518) is a variant of Chess960 and so are the other 959 positions. There is no difference that I can tell. Chess960 is not a variant. It is a generalised set of rules that determine all the possible positions of pieces on the back rank without violating any past rule. Not a single rule of chess is violated in the process, not one.

Aaron Grabinsky: hmm, I didn’t know about that! I’ve always played chess, lol.. Pretty new to 960

chess959: But you’re playing so creative…

Aaron Grabinsky: But it sounds cool! Yes, thank you! I actually like chess 960 better!,,, in a way

chess959: I can only compare your games with Sergey Volkov (GM) or very strong FM Jan Gombac: my main training partners currently.

Aaron Grabinsky: How did they compare?

chess959: I mean the quality of your playing very close to GM level.

Aaron Grabinsky: Cool :) that’s nice, minus the theory advantage in normal chess. I’m much closer to GM level then… well, that’s interesting.

chess959: Bobby Fischer was a genius and so often he used language in a way that we are not familiar with. We think we understood him but actually we were not listening, we were just operating off our own assumptions of what we think he meant. One of the biggest controversies is what Bobby meant when he talked about “pre-arranged” chess games…..

It sounds like match fixing……..I used to get confused about what Bobby was talking about. But Bobby was talking about “pre-arrangement” in the sense that both players have organised what they are going to play on the board before they get there (independently from each other).

The idea of “pre-arrangement” is that as Bobby noted, it should be stated up front (acknowledged rather than blindly accepted). What is the difference between playing from an opening book in your mind, compared to if both players actually used a physical opening book as they were playing through the opening?

Aaron Grabinsky: Well, I suppose it would be more beneficial to use the one in your mind,,, as your memory would be stimulated. But, I’m a little confused, lol. Physical opening book?

chess959: It means the books you can open in your OTB games.

Aaron Grabinsky: Oh, I’d say the difference is sight vs memory.

chess959: In Chess960, memorization is laterally spread rather than longitudinally deep.

Because there are small subsets of critical start positions that need to be memorized in Chess960, players will memorize variations laterally across a subset of positions rather than longitudinally deep in one position as we do in traditional chess. Therefore the overall memory burden is no greater than traditional chess. In fact I can predict already that in future generations of Chess960 players, the total quantity of memorization that we now see in traditional Chess (SP518) will be exactly mirrored in Chess960. There will be great benefits in memorizing certain start positions. However, this practice of memorizing openings will never be at the expense of general creative over-the-board opening play as we see today in traditional chess, because the memory task in Chess960 is so monumental that conceptual thinking in the opening will always be the dominant mode of thinking.

Aaron Grabinsky: This sounds like an improved form of chess, it could be the future! Very interesting.

chess959: Exactly. It is the future.

Aaron Grabinsky: It might just replace chess.

chess959: You are a smart guy.

Aaron Grabinsky: In fact, I think it will! cool :)

chess959: But there is one problem: and a big one.

Aaron Grabinsky: What?

chess959: Very very big one: MONEY

Aaron Grabinsky: How so?

chess959: Sponsors and current chess oligarchy.

Aaron Grabinsky: Oh, well it will have to be advertised and promoted and I hope it will come through though.

chess959: Ok Aaron. Thanks for talking to us.

Aaron Grabinsky: Well, I really like 960! Thanks for being interested in it and introducing me to it more :) Good talking with you too, and see you Tuesday for more 960! :)

chess959: yeah,,, have a good day!

Aaron Grabinsky: okay, cya later! you too.

So earlier, white definitely had to be more aggressive with his stakes in the center.

19. Nh2 d4 {now black should be fine with the center closed. Also, white has concrete problems with the h-pawn.}

20. Bf3 {probably forced.}

20… Bxf3 21. Nxf3 Nxh5 {Black is now better.}

22. Re4 {Re2 with the same idea, but not getting hit with Nf6, is stronger.}

22… Nf6 23. Re2 Qd5 24. Bh2 Kb7 25. Re5 Qc6 26. Re2 h5 {Black’s trying to play h4, h3 and undermine the knight, however, he missed Ne5!}

27. Ne5 Qe8 28. f4 {much stronger is Rfe1! with Nxf7 to come. This is what black had under-estimated with h5. White should then be back to slightly better again.}

28… Nd5 29. f5 {Now Rfe1 runs into Nc3!}

29… Nec7 30. Rfe1 Nc3 31. Rf2 Rg8 32. Nc4 {white’s position looks threatening, but black only needs to show some precision to avoid the worst of it.}

Qd7 33. Nd6+ Ka6 {The king is quite safe on a6.}

34. Nc4 N7d5 35. Qg5 {maybe Ne5 here?}

35… Rae8 {taking over the crucial e-file, as black’s powerful knight on c3 prevents Rfe2.}

36. Rxe8 Rxe8 37. Bg3 Ne3 38. Qxh5 Nxc4 {preparing Ne4 with a decisive edge.}

39. dxc4 Ne4 40. Rf3 Nxg3 {This should be winning for black now.}

41. Rxg3 Re1+ 42. Kh2 {Kf2, Qe7 is dangerous at the very least.}

42… Qd6 {very strong, pinning the rook very unpleasantly and threatening Re3.}

43. Qf3 Re3 44. Qf2 Qe5 45. Kh3 g6 {This is hopeless.}

46. Rxe3 dxe3 {So, earlier white probably should have played d4! striking in the middle with a good game. Also, d3 in the opening was weaker than an immediate exd5 and then d4 for white, keeping the light-squared bishop active.} { White resigns } 0-1

1. e4 b6 2. Nc3 {On second thought, white should probably play Ba6+! here, with an annoying bind. b6 is probably inaccurate.}

2… a6 {Yes, now a6 is covered. But it seems like black is wasting time as a result of b6.}

3. f3 {Intending Bf2 and maybe d4.}

3… e5 4. Bf2 Ne6 5. Nd5 {a good outpost, taking advantage of the fact that c6 is hard to achieve right away.}

5… Ng6 6. Ng3 Bc5 {Maybe Ne7 is better, knocking back the d5-knight. With the text, black loses the right to castle.}

7. Bxc5 Nxc5 8. Nf5 Kd8 {Maybe going the other way, with Kb7 is safer.}

9. g3 {Just stopping Nf4, and contemplating Bh3.}

9… c6 10. Nde3 d5 {probably not a good idea with black’s king stuck in the center unable to castle. Better is Ne7, trying to trade and keep things  closed. Piece trades relieve black’s position somewhat here.}

11. exd5 cxd5 12. d4 {So now black is worse I think as a result of d5. The center is being opened very quickly.}

12… Ne6 13. b3 {If dxe5, maybe d4 is troublesome. The text keeps everything under control.}

13… exd4 14. Nxd4 {The d-pawn is now weak as well as black’s exposed king.}

14… Ne5 {A blunder, unfortunately losing immediately. However, black’s position wasn’t great anyway. d5 and Kd8, as well as b6, were probably errors. Finally, black could probably have held the balance with Kb7 on move 8. And even before d5, black’s position was tenable. }

15. Nxe6+ { Black resigns } 1-0

1. c4 Ng6 2. b3 {A good idea for white, like I mentioned in an earlier game, the bishops are strong.}

2… c5 3. Ng3 b6 4. d4?! {possibly premature. Maybe e3 and then d4, maintaining the pawn center. It’s not that big a deal, but I do have an extra pawn in the center now. (D & E for me vs E for white)}

4… cxd4 5. Bxd4 d6 {e6 might allow c5 for White, so d6 first.}

6. Be4!? {interesting decision by white. Makes sense though.}

Bxe4 7. Nxe4 e5 {This might look counter-intuitive, based on my now weak d6 pawn, but my potential center with e5 and f5 most likely makes up for that. There are similar positions in the
mainline Najdorf.}

8. Bb2 f5 9. Nc3 O-O 10. Nd5 {maybe Nd3 with idea of Nb4, clamping down on d5 is good. If I stop this with a5, then b5 is weak, as well as d5.}

10… Nce7 11. e3 Kh8! {This move is good in that I’m planning to rid myself of my weakness by playing Nxd5 Qxd5 Ne7 and d5. Notice Qxd5 is not check now.}

12. Ne2 {Maybe Nc3, simply retreating, is better. Then my knights are kind of stepping on their toes. They both want to be on e7, and my d-pawn isn’t going anywhere.}

12… Nxd5 13. Qxd5 {If pawn takes, then d6 is covered and black can turn his attention to the king side.}

13… Ne7 14. Qd2 d5 {mission accomplished!}

15. O-O-O? {This move is bad, as White c-pawn will now be isolated at the very least. Much better is cxd5 and then after Nxd5 white might castle short or possibly long, as his king will be safer than in the game.}

15… dxc4 16. Qb4 Qc8 17. bxc4 Nc6 {with Na5 to come, most probably winning the c-pawn.}

18. Qc3 Na5 19. Ba3 Rf7 20. c5 Qa6 {Things are getting dangerous for white. Nc4 is a problem (not to mention white’s hanging knight), and white’s king is wishing he were on the other side of the board!}

21. Qd3 {I’m not sure what else.}

21… Nc4 22. Bb2 Qxa2 {So yea, this is probably resign-able. White’s king is getting ambushed, and he is down material.} { White resigns } 0-1
