| Sep-05-25 | | stone free or die: I'd start with Qh7, and then shepherd the king over to the a-file on the 7th rank, then back to a-file, capture the bishop and advance the g-pawn to promotion. Trouble is the box is too big, the king has to be on the a-file (outside the box) when the bishop is captured. So, I realized I didn't have the patience to try to visualize it out - not being able to find any clever forking idea - and just finished it with an engine. It's a total grind - the Black king has to be driven all the way to the White side of the board. A grind, but instructional (though I wonder just how many games I'd be able to utilize it). |

 | | Fusilli: OK, I stopped reading <sfod>'s post when he mentioned the engine. Until then, that's what I was thinking. However, the black king on a-8 doesn't work. With the black king on a8, 2.Qh7 Kb8 3.Qxh3 gxh3 4.g4 Kc8 and draw. Black made it into the c4-g4-g8-c8 square on time. So, the question is, can white drive the black king down where it can't get inside the square (g4-c4-c8-g8) in response to white's g4 advance? That is, when white plays Qxh3, the black king should be on either the second row or the a-file. It will never be on the a-file, since if it were, it will move to the b-file when the white queen goes to the h-file, before Qxh3. |

 | | Fusilli: OK, I see it, but it's insanely long to write! So, I'm just noting the plan. The procedure I see involves white driving down the black king row by row, but necessarily allowing the black king to momentarily move toward the kingside, if it wants to. It starts with driving the black king to a8. At that point, the white queen is on d7. Then, 1.Qe8+ Kb7 2.Qd8 Kc6 3.Qe7. Then it depends on what black does, but it looks to me that the black king will be pushed toward the a1 corner. When white moves the queen to the h-column, the black king must be on a1 or b1. (If it is for example, on a2, 1.Qh# Kb3 2.Qxh3 gxh3 3.g4 Kc4=) |

| Sep-06-25 | | stone free or die: Hi Fusilli - I'm pretty sure you got farther than I did, and we both had the rough idea. But, being precise, I have to take issue with this statement: <"When white moves the queen to the h-column, the black king must be on a1 or b1."> White can allow the king to be on any on the 1st rank, so long as the queen can get to the h-file. . |
|
| Sep-06-25 | | stone free or die: (And since I cheated, and used an engine, I can also say that it's not mandatory to drive the Black king to a8 either - though it's natural to think it (I think!)) |
|
Sep-07-25
 | | Fusilli: <sfod> yes, anywhere on the first row. Noted on possible different starting points. |

 | | OhioChessFan: You have it. The two important principles are getting the King outside the box and the power of a Queen a Knight's move away from the opposing King. And indeed Ka8 Qe8+. One other point worth mentioning: In some lines, e3 is a crucial square Black can't cross as it shrinks the box against the King a little. |

 | | Fusilli: <OCF> I'm kind of proud of myself I got it. The word puzzle was apt! Where did you source it from? |
|
Oct-01-25
 | | OhioChessFan: Sorry, I missed this request and in the meantime, I forgot the source. I get a lot of puzzles as YouTube suggested videos and think that was the source. |

 | | OhioChessFan: From a 3/2 game. I'm White and in bad shape. Down a Pawn, going to be two Pawns soon, and getting crushed positionally. click for larger viewI tried Ne3 just to generate some activity. Stockfish said it was objectively best, to my surprise, although there aren't many attractive alternatives. I was pretty sure I saw what would happen if Black made the wrong move in response . He did. What plausible move did Black play to immediately give me the draw, and what should he have played? |

 | | Troller: I am guessing he took on a3 and then his Queen got chased around by the rooks without an escape square. Chess is funny that way, there are many squares in the White camp but as long as a4 and c2 are covered he can never really get away. A move like ..Re3 should be winning, probably also others. |
|
| Oct-22-25 | | areknames: I was also thinking Black played ...Qxa3. It does seem the Q is trapped indefinitely after that. |
|
Oct-23-25
 | | OhioChessFan: Yes, Black played Qxa3. The only squares available for the Queen are a2, a3, b2 and d2. Probably Re3 is best but a random Rook move is likely winning too. |
|
Oct-26-25
 | | Fusilli: Wait, I agree that Qxa3 is a bad move, but I thought the queen can escape... only that black gets himself in a losing position, so it's better to accept the draw. Specifically:
1...Qxa3 2.Ra1 Qb2 3.Rfb1 Qe2 3.Re1 Qd3? 4.Rad1 Qg6 5.Rxd7 Nxd7 (only move) 6.Rd1 (or Qc7, but Rd1 threatens Rxd7, more subtle) Qf6 (only move, I think. To h6, Qc7 threatens rook and knight) 7.Qc7 Qe7, and isn't black all tied up while white has a free knight?  click for larger viewIf white can't stop Kf8-Ke8 and black unties himself, white can surely gobble down the a and b pawns at least. And even after 8.Qxa7 Kf8 9.Qxb6 Ke8 white still has 10.Qc6 and black is still all tied up. Does that win? Now tell me what I missed, because I did not set up the engine. Regardless, black should NOT get into this and take the draw instead! |

 | | Fusilli: <Obvious Troll: <Fusilli> Did you quit playing OTB tournaments?> I may have. I didn't plan it that way, it's just happening. I get very tired from playing (and also from traveling). And I am so busy with work. I most definitely quit playing OTB with long time controls (anything longer than G90). |

| Nov-06-25 | | stone free or die: (Hint alert!)
Hmmm, don't think it's a perpetual check kind-of-thing. |
|
| Nov-06-25 | | stone free or die: (Actually, there kinda is!) |
|
Nov-06-25
 | | OhioChessFan: Yep, there's a sorta kinda perpetual involved. |
|
| Nov-06-25 | | areknames: 1.Rb7+ Kc8 2.Rb5! and if the pawn queens it's stalemate after Rc5+. |
|
Nov-07-25
 | | OhioChessFan: Yes. A couple trivial lines. 1. Rb7+ Ka8 2. Ra7+ Kb8 is clearly a repetition. If Black underpromotes, the White Rook draws. |
|
| Nov-07-25 | | stone free or die: Underpromotes to a rook, of course (B or N would lose). |
|
Nov-07-25
 | | Fusilli: <areknames: 1.Rb7+ Kc8 2.Rb5! and if the pawn queens it's stalemate after Rc5+.> Yup. You beat me to the punch. Nice. |
