| Oct-20-11 | | pogotheclown: I was initially puzzled because there doesn't seem to be a huge amount going on but then I spotted ..d3 making a square for the knight. The queen gets attracted to d2 and voila, the knight fork seals white's fate. Missing this in a blitz game is forgivable but a correspondence game? That's pretty poor IMO. Three minutes. |

| Oct-20-11 | | CHESSTTCAMPS: In this opening position, white is up a pawn (c5), but has paid a big price. The white knights are decentralized and the white LSB is off the board, leaving black in control of the center and key light squares. With the threat of 15.Qxe4, white probably expects 14... Nxd2 15.Qxd2 b5 16.cb ab 17.b3 with a safe position. But there has been a little oversight. 14... d3! gains a critical tempo and wins at least a piece for a pawn: A) 15.Qxd3 Qxd3 (Nxd2 16.Rfd1 Qxd3 transposes to the same) 16.exd3 Nxd2 17.Rfd1 Nf3+ and black has a piece for two pawns with an iron grip on the position. B) 15.exd3? Nd4 16.Qd1 Nxd2 17.Re1 (or Qxd2) N2f3+ wins at least a rook. C) 15.Qc1/d1 de 16.R moves Qxd2 leaves black a bishop up. Most likely, white resigns after move 15. |

Where is David Zechiel with its brilliant comments? xD |

| Oct-20-11 | | CHESSTTCAMPS: <sevenseaman: <tacticalmonster: theme: overloaded piece>
Which piece is overloaded and what is the overload? Did knowing the theme prompt the solution? > This is an interesting question. Designating the theme as "overloaded piece" is a little bit subtle. The queen is the overloaded piece, obligated to defend Bd2 and also obligated to defend the fork square f3. To be aware of the potential queen overload, you already have to see the Nc6 coming into play and the royal fork beforehand. You could also designate the theme as "opening lines" (first post of <Phony Benoni> - opening the d-file for the BQ is part of the combination), "Clearance of a square" (<Isolani> - the BN must get access to d4), or even "removal of defender" (diversion of the white e-pawn is required for the royal fork at f3). I've tried categorizing tactical problems by theme as a teaching tool, and there are usually multiple categories that could be used on any one problem. In any case, designating a tactical theme seems to work for <tacticalmonster> and others may find it useful. |

| Oct-20-11 | | Memethecat: my 1st idea was <14...Nxd2. 15Qxd2 Bg5> & then push the d pawn & N forward to try & fork K & Q, too convoluted.
I looked at <14...d3> several times before realising the problems it could cause. Whites replys : A<15Qxd3 Qxd3. 16exd3 Nxd2> & a B is lost. B<15exd3 Nd4> & its difficult for the snow Q to find a safe square, even <16Qd1 Nxd2> leaves white helpless because of the potential fork. And the big guns are yet to enter the fray. I've probably missed lots, time to check it all out! |
|
| Oct-20-11 | | eblunt: < CHESSTTCAMPS:> You could say the white e pawn is the overloaded piece, since it's failure to protect both the d3 and f3 squares is what undoes white |
|
| Oct-20-11 | | CHESSTTCAMPS: Good point. |
|
| Oct-20-11 | | kevin86: Missed it by a mile-The simple pawn move affects white's game like a bulldozer. |

 | | LIFE Master AJ: After I ran my checklist, I started my stopwatch ... after taking an eternity to find the solution yesterday, I figured today would be even worse! However, (unlike yesterday, when I felt like a chessical dunce); here - I hit upon the winning idea pretty quickly. 14...d3!; 15.PxP/d3▢; (White cannot capture with the W♕, as after an exchange of the ladies, the White-DSB on d2 goes for nothing.) 15...Nd4; 16.Qd1▢; (Other moves lose the Bishop on d2 ... or worse yet; </= 16.Qc1??, and now 16...Ne2+; forking the royal couple.) 16...NxB/d2; "  " for now if 17.QxB/d2, then 17...Nf3+; picking off the White Queen for a song. I would think Black would resign to save postage ... time to check. |
|
| Oct-20-11 | | dufferps: Okay, black will gain a piece. Do players at this level always resign after just going down a piece? Checkmate hardly appears imminent to me. |
|
| Oct-20-11 | | eblunt: <dufferps> Agree totally , after the 15. Qxd3 line white is down a Bishop but for 2 pawns. Black certainly has a very dominant position, but I'd certainly give that a go as white in a club game, for half a dozen moves at least. |
|
| Oct-20-11 | | MiCrooks: I actually found this idea a lot quicker than yesterday...there simply were not a lot of tries for Black. So knowing that it was a puzzle pushing the d-pawn to clear d4 for the other Knight popped right up. Then it was just a matter of seeing the fork. |

 | | doubledrooks: After taking too long to find the solution to yesterday's puzzle, I found 14...d3 quickly, then spent several minutes calculating the variations, one of which had a blunder at the end: 15. Qd1 dxe2 16. Qxe2 Nxd2 17. Rfd1 Nd4 18. Qe3 N2f3+ 19. Kh1 Qa4 20. Nc3 Rad8 and now I didn't remember that the bishop is en prise. |
|
| Oct-20-11 | | Memethecat: <dufferps> <eblunt> being down a B is bad enough but the black Ns also hold the centre & threaten the R & forks galore. To make matters worse the central files are wide open. The lack of pawns in the centre is useful for blacks B as well. Taken as a whole I wouldn't like to be in whites shoes. |

|
| Oct-20-11 | | MaxxLange: <Do players at this level always resign after just going down a piece?> In general, yes, they do. Also: this was a correspondence game. Why waste the postage on it, after this start? |
|
| Oct-20-11 | | Once: That's a deliciously economical move. 14...d3 vacates d4 for the Nc6, threatens to open the d file for Qxd2 and if 15. ef black gets to play one of two draughts moves Nd4-Nf3+ or even Nd4-Nxd2-Nf3+. It's as if time freezes for the white pieces and the black knights get to make two or even three free moves in bullet-time. Neo: What are you trying to tell me? That I can dodge bullets? Morpheus: No, Neo. I'm trying to tell you that when you're ready, you won't have to. |

 | | FSR: 14...d3! 15.exd3 (15.Qxd3 Qxd3 16.exd3 Nxd2; 15.Qd1 dxe2 16.Qxe2 Nxd2 17.Rfd1 Nd4!) Nd4 16.Qd1 Nxd2 toasts White. |
|
| Oct-20-11 | | TheBish: T Demetriescu vs Nagy, 1936 Black to play (14...?) "Medium", White is up a pawn.
After glancing around the board for a couple of minutes, I don't see any alternate moves besides 14...d3, clearing d4 for the other knight and protecting the Ne4, so that will be my starting point. After just under a minute (I timed it this time) I've concluded it wins. 14...d3! 15. exd3
The alternatives are: (A) 15. Qxd3 Qxd3 16. exd3 Nxd2 (winning a bishop for two pawns) and (B) 15. Qd1 (or 15. Qc1 dxe2 wins) dxe2 16. Qxe2 Nxd2 17. Rad1 Nd4! followed by ...Nf3+, e.g. 18. Qxd2 Nf3+ wins the queen. 15...Nd4 16. Qd1 Nxd2 wins the bishop for two pawns, as 17. Qxd2 Nf3+ wins the queen. |
|
| Oct-20-11 | | stst: Simple enough, just push the Pawn -d3!
If PxP, Qd4 ready for attack.
If QxP, QxQ, PxQ and NxB gains a B!
Rest is easy... |

| Oct-20-11 | | stst: <Where is David Zechiel with its brilliant comments?
?? - one can make them too!? |
|
| Oct-20-11 | | estrick: Should have checked back in again sooner. Now that it's the end of the day, people are probably done with this POTD. Anyway, I'm surprised that nobody mentioned theory about the IQP. People talked about clearing a square for the knight, and the overworked piece, . . . but not the IQP. I've been working on trying to understand this concept recently, and the main idea seems to be to use the IQP as a weapon, and keep pushing it down the middle of the board, whenever you get the chance to do so. (I realize that technically this might not have been a true IQP, since White still had a c-pawn.) So, when I saw a space in front of Black's d-pawn, the first thing I looked for was to see what kind of havoc it could wreak if it went forward. Since it attacks White's queen on c2, White has to respond to Black's advance of the pawn. Then, it was just a matter of working out the next few moves and making sure that Black does indeed win a piece in all variations. |
