| Aug-25-21 | | stacase: Yeah, 35...Rxg2+ and Black can get some checks in but ultimately White's King can escape the barrage to d3 and then what? Uh, will you just take a look at that! White sees it too, and tosses in the towel. 35...Rxg2+? I doubt I would have played it over the board, but since it was a puzzle ... |
|
| Aug-25-21 | | agb2002: Black is one pawn down.
White threatens Qxc2.
Black can attack the white king with queen and knight after exposing it with 35... Rxg2+ 36.Kxg2 (36.Kf1 Rf2+ 37.Kg1 Qg4+ 38.Kh1 Qg2#; 36.Kh1 Qh3+ 37.Nh2 Qxh2+ or Nf2# or Ng3#) 36... Qg4+: A) 37.Kf1 Qh3+ 38.Ke2 (38.Kg1 Qg3+ and mate next) 38... Qg2+ 39.Kd3 Nf2+, followed by Nxd1, wins decisive material (the white knight is hanging). B) 37.Kh1 Nf2+ as in A.
C) 37.Kh2 Qg3+ 38.Kh1 Nf2#. |

 | | Dionysius1: Herumph! I saw as far as 38... ?g2+ and decided that's what I would play in a real game, because there must be something good. Since White resigned (because of 39. ?d3 ?f2+ 40. ?c2 ?xd1 41. ?xd1 ?xf3+ and Black is a ? for ? up), I'm claiming I solved the puzzle (resignation ends the game), but it's a bit streaky. I'm sure I used to be able to calculate further than I can now! If it's true that as calculating power wanes with age, so "instinct" improves, then I claim I was relying on the instinct part of my solving skill to see me through. Is that acceptable do you think? I expect younger players to disallow me! |

 | | Teyss: Also a Wednesday puzzle in 2008.
<areknames: Good Wednesday puzzle. It's crucial to see the 39...Nf2+ fork at the end of the forced game line.> The fact the fork is already needed on a simple line (B of <agb2002>) helps when the line becomes longer, as played in the game: since we already envisaged it, we rapidly see how to finish instead of losing time on variations. <Dionysius1> Since I'm not a younger player I won't disallow you. |
|
| Aug-25-21 | | AlicesKnight: Found the game line after a little, once I saw the eventual ... Nf2 fork coming. A nice outcome that does not seem 'on' until Qd1 gets played. |
|
| Aug-25-21 | | Brenin: <AlicesKnight>: You're right about 35 Qd1, setting up the fork Nf2+. Instead, 35 Rf1 would have held the fort: 35 ... Rxg2+ is still on, but it gets only a draw by repetition after 36 Kxg2 Qg4+ 36 Kh2 Qg3+ 37 Kh1 Qh3+ (37 ... Nf2+ 38 Rxf2) 38 Kg1 Qg3+. |
|
| Aug-25-21 | | Stanco: My first take was Rxg2+ and it took me about 10 seconds to solve the variations. |
|

| | Teyss: <Stanco: My first take was Rxg2+ and it took me about 10 seconds to solve the variations.> You're fast. It took me 2-3 minutes to figure out the variations, excluding another 2-3 to evaluate the position and make sure there was no better move. Just <reading> each of Brenin's and agb2002's solutions took me more than 10 seconds. |

| | Dionysius1: Ah, I see from my attempts earlier today to show figurine notation by putting swirly brackets round bits of the text, the question mark problem is still with us. I meant: "I saw as far as 38...Qg2+" and "Since White resigned (because of 39. Kd3 Nf2+ 40. Kc2 Nxd1 41. Kxd1 Qxf3+ and Black is a Q for R up), I'm claiming I solved the puzzle" Ta, <Teyss> |
|
| Aug-25-21 | | little ernie: Clue is that Black's rook is hanging.
Then it must be moved or guarded.
Only guard is by moving knight.
But no knight move is useful.
Then rook must be moved.
Only effective move is ...Rxg2+ |

Maybe, though of course "puzzle instinct" is very different than game instinct. Here you know that a quick win is around the corner, so the most aggressive move is likely the right one.
I impress myself most when I see the win just by studying the position (in this case, seeing the eventual knight fork). When I don't see the win and proceed on "puzzle instinct", sometimes I find the right line. That's the only way I can solve a Friday or Saturday. |

 | | perfidious: <Dion....If it's true that as calculating power wanes with age, so "instinct" improves....> Trouble is, endurance also diminishes, a reason why it was extraordinary for Korchnoi to attain his peak as a top-class grandmaster in his mid-late forties, a good ten years later than normal. As to certain types of calculation, at 61 I am still able to perform mental arithmetic with great ease, though I already sense I am not quite where I was a few short years ago. No-one who knows me realises it, because even now it is well beyond their capabilities. |

| Aug-25-21 | | Once: It was the nearly knight fork I noticed first. I don't know why. These days my brain doesn't think in straight lines. So 35...Nf2 is a queencheck. What's that? A queencheck isn't a thing? Fair enough. If I can deflect the white king to h1 or h3 my nearly fork becomes a gotcha fork. And that might make Nf2 into a queencheck one of these days. Nah, that's not working. Rewind and try something new. Now 35...Rxg2+ appeals because it's one of Purdy's smiting moves. After 36. Kxg2 we have to follow up with 36...Qg4+, because ... well just because. Chase the white king to h1 and we have the aforementioned Nf2+. Or chase him to d3 and we have Nf2+ again. Spell check the alternatives, making believe that we're <agb2002>. Can't claim I solved it in 10 seconds, but at my age it takes you all night to do what you used to do all night. |

| Aug-25-21 | | Stanco: <Once> please don't get me wrong.
l'm not active from 2004 or 2005, if I recall it correctly.
My highlights:
I won games against Ivan ?aric (he became U18 world champion in 2008), and Zdenko Plenkovic (was a Croatian U18 champion then) in a tournament back in 2003.
Ivan Saric, Filip Ljubicic and I ended the tournament 1st equal in points.
Here is my game against Ivan Saric:
S Rakuljic vs I Saric, 2003Me at the top of the game:
In a short time following that tournament I decided the competitive chess is stressful, and also realized that I will never become a GM. I didn't play much and never reached 2000, but I believe I played 2200 at my peak? Now I only kibitz and solve.
Recently I kibitzed Split Open 2021, tournament which today's game white Mladen Palac won 😉 |

| | Dionysius1: <perfidious> Really interesting about the mental arithmetic. My favourite is calculating squares when I'm waiting for something (there seems to be more of that). The unexpected pleasures are my memory isn't what it was, so I don't think I'll have them by heart any time soon, and that there's no discernible pattern, so the short cuts are severely limited! And if I keep my face straight no-one knows I'm doing it, so it doesn't get competitive :-). If I may ask, what kind of mental arithmetic do you do? |
|
| Aug-26-21 | | drollere: i had the game line, with the N fork at f2 after Kd3. i also made sure that declining the offered R was also fatal. |

| | perfidious: <Dion>, such things as 45 per cent of 60 and somewhat more complex calculations; multiplying 53 x 32 or some such; totting up strings or columns of numbers like 36, 77, 84, 32, 102; that sort of stuff. Been able to do that as long as I can remember. My memory is also still excellent--pity so many things I recall are those I would just as soon forget. (laughs) |
|
Aug-26-21
| | Dionysius1: Pretty much like me, I think. Yep, I'd prefer a selective memory I was in control of to a perfect one any day! |
|
Aug-26-21
| | perfidious: <Dion>, I love opponents who have selective memory; they always recall the one hand they made to win a huge pot whilst forgetting the dozen which cost them those pots. |
|
Aug-26-21
| | Dionysius1: Nice one! Best to be in control of the selective memory, as in "Memory, bring back to my mind those hands that are relevant to this one, not just the ones that made me a huge pot" |
