  michael104: 15.exd3 Nd4 16.Qd1 Nxd2 17.Qxd2 Nf3+
Oct-20-11  chesswonders: White has to lose a piece here.
Oct-20-11  Quentinc: 15. exd3 Nd4. with Nf3+ to come. If 16. Qd1 Nxd2 followed by Nf3+. Vastly easier for me than yesterday's, which I didn't get.
Oct-20-11  nateinstein: If Qxd3, then Qxd3 for black, then exd3, and Nxd2 winning a bishop. If exd3, then Nd4 threatening queen, queen moves and then Nf3+ (since e pawn no longer guards f3 square) and then black wins the bishop on d2 since it has both knights on d2.

<14...?>

Probably not a mating attack. White does have some loose light squares on h3 and f3, but the latter is guarded by the e-pawn.

Black's ♘e4 is attacked. 14...Ng5 hits a weak square, but to no effect. 14...Nxf2 15.Rxf2 would only work if the bishop could come in, and that's not likely. Or maybe if the queen could hit the diagonal, say from d4.

<14...d3> is a nice line-opening idea, and 15.exd3 opens up the f3 square. But what are we opening lines for? Well, it does make room for ...Nc6-d4, hitting the queen.

Of course, White can always play 15.Qxd3. Wait, no he can't--Black trades queens and wins the ♗d2! Now we're getting somewhere!

After <14...d3>, White can't decline the pawn: 15.Qc1/d1 dxe2 hitting the rook with a double attack on the bishop. After 15.exd3 Nd4 how does the queen protect the bishop? 16.Qc3 or 16.Qc1 allow 16...Nxe2+ forking, and 16.Qd1 Nxd2 17.Qxd2 Nf3+ takes advantage of the f3 hole.

<14...d3> is a move that doesn't look like a lot at first, but it grows on you.

  estrick: My first instinct was that the d-pawn should be rammed down the middle.

This seemed easy, but I missed the cross-pin tactic in yesterday's puzzle.

  rhickma4: After not having a clue yesterday, I think I can see this one.

14...d3 15.exd3 Nd5 16.Qd1 (or Qc1) Nxd2 wins a piece

14...d3 15.Qxd3 Qxd3 16.exd3 Nxd2 wins a piece

14...d3 15.Qd1 (or Qc1) dxe2 also wins a piece.

  Phony Benoni: Here's another example, from S Gotthilf vs Capablanca, 1925:

Once again, <24...d3!> cleared the way for ...Nd4 while stripping the light squares on White's kingside of their last shred of protection. White resigned.

Oct-20-11  Old Wolf: How could you make such a terrible move as Qc2 in correspondence
Oct-20-11  mohannagappan: 14. ...d3
Oct-20-11  rilkefan: Not my week. Looking over the possibilities I saw ...d3 as a standard move, but then started looking at ...b5 instead. Which, pushing the pieces around, just doesn't work.

  al wazir: Got it. (I followed <dzechiel>'s dictum: Look for the most forcing move.) Why didn't I see yesterday's as easily?
Oct-20-11  tacticalmonster: theme: overloaded piece

14 d3

a) 15 exd3 Nd4 16 Qd1 Nxd2 win a piece bec if 17 Qxd2?? then 17 Nf3+

b) 15 Qxd3 Qxd3 16 exd3 Nxd2 17 Rfd1 Nd4!

c) 15 Qd1 dxe2 16 Qxe2 Nxd2 17 Rfd1 Nd4! 18 Qg4 N4f3+ 19 Kh1 Qd3

Time: 1 min

Oct-20-11  Orhtej: Nice pawn sac to win a piece..it is a sacrfice that would win a piece in force whatever you reply..either accept it or decline it!

  sevenseaman: Looked at it for 3 minutes or so; no coup comes to mind. Nxd2 looks drab. 5 minutes now, still nothing.

<Missed it> is the verdict.

~~~~~~~~~~~~~~~~~~~

d3? No enlightenment till I saw <tacticalmonster>'s analysis. Life is like that. The higher you go, the greater the fall!

Oct-20-11  Isolani: Clearance of a square, in-between move then fork - very nice.

Amazingly I got that one right away, yet I could not find that simple pin from yesterday's puzzle - go figure.

BTW, it's not every day you see a fianchettoed knight.

  sevenseaman: <tacticalmonster: theme: overloaded piece>

Which piece is overloaded and what is the overload? Did knowing the theme prompt the solution?

(I might as well get some theory under my belt I am so bereft of - if you do not mind.)

To my mind it looks an expert user of the Ns in tandem, like say Vishwanathan Anand will be perfectly at home in this kind of situation.

Oct-20-11  abuzic: 14...d3

- 15.exd3 Nd4 16.Qd1;
<16.Ba5 Qxa5 17.Qd1 <(17.Qb1 Nf3+ 18.Kh1 Qxb1 19.Raxb1 <[19.Rfxb1 Nxf2#]> 19...Nde2)> 17...Nd2>;

16...Nxd2

- 15.Qxd3 Qxd3 16.exd3 Nxd2 17.Rfd1 Nf3+ 18.Kh1

- 15.Qd1 dxe2 16.Qxe2 Nxd2

  M.Hassan: "Medium" Black to play 14...?
Black is a pawn down.
Advancing of d4 pawn is the key move I think!
14.......d3
White can take it with queen or e pawn
Let us consider each case:

15.Qxd3 Qxd3
16.exd3 Nxd2
Black is now ahead by a Bishop for two pawns.

OR

15.exd3 Nd4
16.Qd1 Nxd2
<if 17.Qxd2 Nf3+ and White Queen is lost> 17.Re1 N2f3+
18.Kh1 Nxe1
19.Nxe1
Still Black is ahead in materials

  Treestar: <14.d3 15.exd3 (or Qxd3 Nxd2) Nd4 16.Qd1 Nxd2 17.Qxd2? Nf3+>

No cross-pin today. Instead, as yesterday, decoying the queen by exchanging minor pieces, but the final blow is a fork rather than a pin. Just check for any attempts by white to regain the piece, but no, so safe to play d3. Easier than yesterday, this solution came naturally from the memory bank.

  whiteshark: As a Albins Countergambit player this move comes up rather quickly, if not instantly.

  lost in space: 14...d3! 15 exd3
(15. Qxd3? Qxd3 16. exd3 Nxd2; even 16. Nxd2 directly is winning; 0:1)

15...Nd4 16. Qd1 Nxd2 17. Qxd2 Nf3+

boiiing; a royal fork. 0:1
