| Feb-08-21 | | AlicesKnight: Took a few moments - Rxd5 exploits the Black Q focus points. <Once> is right - do I see it if I am not prompted to look for it? That's why I am not a good enough player. |
|
| Feb-08-21 | | Damenlaeuferbauer: After long pondering, my old friend and compatriot Ludger finally found the nice rook sacrifice 24.Rxd5!,Qxd5 (24.-,Qxc6 25.Rd8+; 24.-,Rxc6 25.Rxc6; 24.-,Bd3 25.Rxd6) 25.Qa3+ against no other than the former English world-class GM Tony Miles. Exactly 30 years ago, he tried to teach me "his" beloved French Defense variation 1.e4,e6 2.d4,d5 3.Nc3,Nc6!?/?! 4.Nf3,Nf6 5.Bg5,Be7 6.e5,Ne4 7.Bxe7,Qxe7, 5.e5,Ne4 6.Bd3,Nxc3 7.bxc3,f6 or 6.Ne2,f6 7.Ng3,fxe5, which is named in Germany after GM Hans-Joachim Hecht and him, but as a French Winawer (1.e4,e6 2.d4,d5 3.Nc3,Bb4) addicted I was not fully convinced. |
|
| Feb-08-21 | | awfulhangover: It took me a long think to find the Qa3 idea. Either it was a hard Monday, or I have a one digit IQ. |
|
| Feb-08-21 | | Diana Fernanda: It's good that chessg is changing, it was necessary to raise the level of the riddles, there were problems that offended our ego for being of an abysmal naivety. Rook x pawn and the white queen will go to square a3. |
|
| Feb-08-21 | | zb2cr: 24. Rxd5 threatens the Black Queen, but if she plays 24. ... Qxd5; 25. Qa3+! and Black gets mated. No reasonable defense presents itself to my eye. Everything that Black can try loses significant material, or falls into a meting net. |

|
| Feb-08-21 | | TheaN: <Once: It's all about trial and error.> Not too much to add. This Monday is in fact trial and error. |
|
| Feb-08-21 | | Cellist: Took me much longer than usual for a Monday. <Once> presented the same steps I contemplated before finding the solution. |

 | | little ernie: Someone once said never use "very" in your writing. Possibly Lester King in "Why Not Say It Clearly ?". This puzzle is not "very" easy. |
|
| Feb-08-21 | | KevinDenelsbeck: Had to work through it, but got there. It helps that Black's pieces are almost perfectly uncoordinated. |

| | chrisowen: Rats d5 alpha no numb que yes afternoon then no accidental emergency no? |
|
| Feb-08-21 | | drollere: this one took some figuring ... mostly realizing that the N had no moves and the R's could not double. OK, you boys sit there and let a lady clean this up. |
|
| Feb-08-21 | | drollere: <We have the advantage of knowing a combination is in the air> in chess there is always a combination in the air, starting with scholar's mate. i play chess on a legacy chess program, but periodically review moves by putting late opening or midgame positions i arrive at in that program into SF to see how it would play them out (me providing the program responses to the SF moves). and i've discovered "there is always a win in there" that involves some tactical or strategic point i had missed. |
|
| Feb-08-21 | | Once: <drollere> Computers are very good at spotting what we miss! What I was thinking about was differentiating between a relatively quiet position and one where a decisive combination was possible. We can't devote the same amount of time to every move, so we have to make a practical decision about when to move quickly and when to wrap the metaphorical towel around your head and switch into puzzle mode for a good long think. If we had arrived at today's position over the board, we would need to make a decision about whether to defend our twice attacked knight or cast around for something juicier. <i've discovered "there is always a win in there" that involves some tactical or strategic point i had missed> Perhaps. Conversely, I've found I sometimes lose games by spending too long analysing speculative tactics when a simpler positional move might save time and make my position stronger. I don't think we can spend all our time at DEFCON 1. That way madness (and time trouble) lies. |

 | | gawain: I worked and worked on this earlier, then set it aside in frustration. After a couple of hours I came back to it and this time I saw the solution instantly. This happens so often! |
|
| Feb-08-21 | | Cheapo by the Dozen: This was Tuesday/Wednesday level of difficulty for me too. But I eventually gave up hope that either a discovered attack on the queen or a direct attack on the bank rank would succeed, and there was little else to try except the game move. |
|
| Feb-08-21 | | 1g1yy: I must confess I didn't see it. I eventually went to the game and now that I was shown the move, well holy smokes, that was easy. Each time this happens to me, I see common mistakes in my thinking that these puzzles point out. So, while I may not get the solution on my own, I'm definitely learning new tactics I need to be aware of when I play. |
|
| Feb-08-21 | | drollere: <I don't think we can spend all our time at DEFCON 1> sure. but nothing i said implied strategic alert was necessary. i find it is much easier to solve the daily puzzle if i simply note the puzzle move, jump halfway back to the opening, then play up to the position. often the puzzle solution depends on a tactical theme that has taken one or two previous moves to prepare; or the opponent has not realized where things are headed. this is easier to see in the development than in the freeze frame. perhaps your problem is spending too much time choosing moves. my problem is overlooking them. not seeing a N fork one or two moves ahead is one of my perennials. |

| Feb-08-21 | | RandomVisitor: 14...Qxd4? is possibly the losing move, better was Bd6 followed by 0-0:

|
| Feb-08-21 | | TheBish: 24. Rxd5 Qxd5 25. Qa3+ looks like a wiener. Is it Monday or Wednesday? Time and days of the week have lost all meaning in these Covid times. |
|
Feb-08-21
 | | monopole2313: Missed it; perhaps the COVID vaccine made me a zombie. Maybe I got the Modelo instead of the Moderna? |
|
| Feb-08-21 | | Schwartz: I only found the solution after ending Qe2 f6 Nd4 from similar moves, because I accidentally had the queen on b5, I played Nd4 and then saw Rx. Initial observations were unhelpful without the important Qa3+. |
|

 | | eternaloptimist: I solved this 1 pretty quickly but I must say that I’m surprised that Miles fell for this tactic. Although that’s what happens much of the time when u don’t castle early w/ ♕s & ♖s on the board |

If you want to post huge engine analysis of move 2 of the opening, may I humbly suggest you do it on the page for this opening here? Sicilian, Alapin (B22) |
