 | | Fusilli: <OCF> Well, I do know that in your place I would be royally annoyed at myself! As for the position... the king there and without castling rights spells trouble. It seems to me that 10.Bxd5 doesn't work, and if 10.Re1 to threaten it, 10...Kd7 and 11.Nxd5 doesn't work (11...exd5 12.Bg4+ Kc7 13.Bf4+ Bd6.) Does 11.Bxd5 work? 11...exd5 12.Nxd5... too tired to calculate what can happen after that. Even with no sac, I can't imagine that not being very dangerous for black. If the king has to go to d7, I suppose once white plays c4, black is horrible... Even if I am too lazy to look at it tactically. So, I am going to go with +3 |

 | | OhioChessFan: Believe it or not, at 20 plies, only .34! Best supposedly is 10. Ne2 Ke8 11. 0-0 It's astounding that engines can defend such positions when humans instinctively think they're positionally lost. Maybe the eval would sink at higher plies. |

<Believe it or not, at 20 plies, only .34! Best supposedly is 10. Ne2 Ke8 11. 0-0> Wait, white is already castled.
The position looks frankly awful, but the computer is telling us it can prevent collapse. As usual, the problem is that in order to do that, black probably has to make amazing moves. From a human point of view, I would prefer to handle black in many +1.34 positions than in this 0.34 one. (I think 20 ply is deep enough for practical purposes.) Did you lose the game? |

 | | OhioChessFan: Oops, I showed the game after White played 10. 0-0 and I resigned. I tend to resign any finger slips. SF says 10. Ne2 is .35 and 10. 0-0 is .34 |

 | | Fusilli: <Oops, I showed the game after White played 10. 0-0> Good to know, because then I was a lot closer to the computer's evaluation! I just checked the position of the diagram with white to play (again), and the computer says +2.35 after Re1 (then Kd7, Nxd5 exd5, c4) or the different order 11.Nxd5+ exd5, Re1+ Kd7, c4. When I ask for more depth, the advantage increases to over 3 at 30 ply. Phew! Apparently, resign is the ?? move, not Ke7! |

 | | Fusilli: Incidentally, you had comfortably equalized by move 10. If it was a Caro Kann, it strikes me as inconsistent for white to play exd5 once the knight was committed to c3. Admittedly, I don't know much about the Caro, but it looks like if you play Nc3 you are planning to keep the tension in the center going. |
|
Aug-21-24
 | | OhioChessFan: Yes, it was 2. Nc3 followed by 3. exd5 which leaves Black with no problems. 9...h6 is pretty standard there but Be7 is fine. Ke7 isn't quite as good. |

 | | Fusilli: My chess formation (with no long-term good coach) was decidedly uneven, unsystematic, and chaotic. As a result, I ended up being a pretty good player in some positions and themes, but I lack knowledge AND instinct (knowledge gives you good instincts, I’d say) in some others. That's why I am tremendously enjoying a video training series on chess.com by Johan Hellsten. It’s called <Every pawn structure explained>. Each pawn structure has a 20-minute video where the GM explains the main ideas for each side, then gives you examples of a <dream position> for each side, and then illustrates with model games for each side. Then there is a challenge section where you go through five puzzles. Not single-move puzzles, but move + ideas puzzles that take a few moves each. Sometimes you win, sometimes you simply make the good positional moves to obtain an advantage. I am learning new things even in positions <I thought> I knew well! If you are not on chess.com yet, I can’t recommend it strongly enough. I used to be on icc, and eventually I dropped it for chess.com. I just need to avoid wasting too much time playing frivolous blitz and use its wealth of resources for training and enjoying the game instead.
My next post shows an example.
(If you are on chess.com, or join it, I am <RealFusilli> there. <Fusilli> was taken! Send me a friend request, but tell me you know me from here or I’ll ignore it.) |

This is the Carlsbad structure. Who hasn’t played it! It can arise from queen’s pawn games, where white ends up with the e3 and d4 pawns and black with the c6 and d5 pawns, and white goes for the minority attack (while black looks for active play on the kingside) or it can arise from other openings where the structure is reversed (e.g., the Colle or the London). That’s the case here, where black is trying to set up a minority attack. The question is: White to move. Should you try to stop the minority attack? Should you ignore it? What should white play? Any takers? |

 | | Fusilli: In the position on my last post, the game continued: 1.b4 a5 2.a3 axb4 3.axb4 Rfc8 3.Nb3 and the knight went to c5, with a big advantage for white. |

Blitz on chess.com.

48…Kg2 is the winning move, then 49.c7 Rc5 and the white pawn eventually falls. Notice that if 50.Rc4, Rxc4 51.Kxc4 h1=Q and if white promotes, Qc1+ is curtains.
My opponent played 48…Kg1 49.c7 and now it's a draw!
 click for larger view
The key is that if now 49…Rc5 50.Rc4 draws! The black king has obstructed its queen and there is no Qc1+. Furthermore, there is no Rxc7 either, since white will have Rc1+ draw (after black promotes) The game continued 49…Rg8 50.Rg4+ (well known and essential trick here--without it there is no draw)

50…Rxg4 51.c8=Q Rg3+ (h1=Q also ends in perpetual) 52.Ke2 h1=Q

 | | OhioChessFan: <This is the Carlsbad structure> Haven't popped in for a while. White definitely wants to set up a Knight on c5 via b3. I think b4 immediately and if Black challenges with a5, then a3. Seems like Lasker analyzed a similar position in one of his books. |
|
Sep-17-24
 | | OhioChessFan: <This is the Carlsbad structure> Okay, I see you gave the line. The important feature is White's Knights just dominate Black's LSB. I'll have a look at the other positions soon. |

 | | Fusilli: OK, in the last diagram I posted (no time to type it again): ...Qxd3!
And black is chairman of the board. |

 | | OhioChessFan: Ouch. Seems so simple after reading the solution. |
|
Sep-19-24
 | | Fusilli: <OCF> Before my opponent played Qb3, I was pondering what to do against it. It does look like a natural move in that kind of position, and the kind of quick move you look at in blitz. Only after Qb3 happen did I notice Qxd3, and not at all instantly! The white position does fall apart. Taking the b7 after the bishop trade (which he did) is risky (and he found out). |

 | | Fusilli: Blitz on chess.com during work break. I am black. White just played 20.Qf4-e5. It threatens the h8-rook. Black to play. The question is, does 20...Bxf2+ win?

I'm Black, 3/2, almost on increments, and have checked Qh4/e7/h4/e7. White decides to ignore the implied draw offer and try for the win and plays Kg8.  click for larger viewI continue with Qe8+. What did I miss?

 | | OhioChessFan: Per your game, Bxf2+ followed by Bd4 is winning. |

 | | Fusilli: <I continue with Qe8+. What did I miss?> You missed your opponent's very fancy suicide!
Ouch :( |

 | | Fusilli: Email I received from a Vanderbilt office in response to an inquiry: "That’s just a default setting it does mean anything all rides are by vehicle you don’t have to worry about it" That is LITERALLY the response I received. No, I did not omit the period at the end of the sentence. Not even that period was there. A run-on sentence four times over.
THIS is an elite university. Or so they call us. Oh, the irony... |
