Apr-12-07  newton296: I saw the threat of mate in 1 after Rxd7 Rxd7 Ne5 and thought white wins only to look at the game and realize I missed g4, and that after Ne5 Qd1+ it is black who is winning. oops!? Guess i'm slipping on thursdays. Anyway . Nice puzzle chessgames. Pretty position that reminded me of a morphy game, but if I remember correctly morphy was tactically more complicated.
Apr-12-07  imatos: <YouRang: Bah! I was too hasty and went for 16. g4 Qxh3 17. Nxe5, but I see now that it's too slow. Black has 17...a6 and now white is challenged to hold things together.>

Same here. :-) I didn't see that Black can prevent the mate by chasing the queen with the pawns.

Apr-12-07  MostlyAverageJoe: <Tactic101: black can't defend the loss of of his rook (and mate, along with it)> Yes and no. Try mating after 17 ... a6.
Apr-12-07  bramdas: I'm really confused. 16 Nxe5 Qd1+?? 17 Rxd1, and the Black Knight can't move as it is pinned. How is 16 Nxe5 not good? What am i missing?
Apr-12-07  imatos: I'm surprised to see that Black is an Elo 2650 (!) grandmaster and yet played straight into a loss by such a relatively simple tactic. Was this played under normal time controls?
Apr-12-07  alshatranji: 16 Nxe5, then 16... a6
Apr-12-07  imatos: <bramdas: I'm really confused. 16 Nxe5 Qd1+?? 17 Rxd1, and the Black Knight can't move as it is pinned. How is 16 Nxe5 not good? What am i missing?>

If 16. ♘xe5, then 16. ... a6 and White can neither mate immediately on d7 nor maintain the pin on the Black knight (17. ♕a4 b5).

Apr-12-07  scholes: <bramdas>After 16♘xe5 black will play ♕xe5 not Qd1+??

I was able to find only ♖xd7 ♖xd7 ♘xe5 ♕d1+ ♔h2

Apr-12-07  MostlyAverageJoe: <MiCrooks: After g4 qxh3 you play Nxe5 not Rxd7. Now the Knight guards the g4 pawn. And if Bc5 you take on d7 with the Rook first, not the Knight, that way g4 is still guarded>

So? The above does not win, as pointed out by Chessmoron:

<chessmoron: 16.g4 Qxh3 17.Nxe5 Bc5 18.Rxd7 Qg3+ 19.Kh1 (3-fold repetition.)>

which is why black does not play 17 ... Bc5, but 17 ... a6, with resulting minor advantage for black.

  chessgames.com: <mkrk17> <I guess i understand Thursday puzzles now. Its something like... you know the "winning move", but you need to twist it a little to get the correct solution.> That's a pretty good description. For Thursday puzzles and later in the week, the Devil's in the details.

<bramdas> <How is 16 Nxe5 not good? What am i missing?> 16...Qxe5

<devilwolfdog> <Can someone run 16. Bf4 through an engine.> Crafty tells us that the self-forking 16.Bf4? is rebutted by ...a6!

Apr-12-07  MostlyAverageJoe: <devilwolfdog: Can someone run 16. Bf4 through an engine. .... Am I missing something?>

No engine needed. The pesky a7-a6 move refutes the 16.Bf4 idea.

Apr-12-07  englishopener: Oh my gosh, I just LOVE knights. Every time I see the fork, it reminds me how beautiful the possibilities of attack with this unique piece are.

  playground player: Thought I had it with 17... Nxe5; but I didn't see Black's sharp response, Qd1 -rats!
Apr-12-07  Crowaholic: Tough one because of move order. Rxd7, Nxe5 and g4 aren't hard to find, but 15. Nxe5 immediately loses to Qxe5 and 15. g4 draws because of Qxh3. And 15. Rxd7 Rxd7 16. Nxe5, which I thought was good, loses to the line pointed out by <Phony Benoni>. Although this just boils down to an exchange of queens and minor pieces, with the loss of the mating threats and pins, the exchange sacrifice now backfires into a (probably) lost endgame.
Apr-12-07  Crowaholic: Another tricky thing to see is that after 16. Nxe5??, Black can play Qxe5 with impunity because by recapturing, White unpins the knight.
Apr-12-07  pubaer: I was thinking about be3, a nice development move, threatening Rd1, I want aware until i read the kibitzing here, that a6 followed by b5 just ruins everything. Chess can be really tough sometimes :(
Apr-12-07  simsan: The first one I missed this week.

I did of course look closely at Rxd7 (and believed that it was a probable 1st move), but I just couldn't find the right follow-up move against which ... a6 wasn't effective.

Nxe5 seemed half-OK. I saw the semi-refutation 17. ...Qd1+.

I didn't see the beatuiful 17. ... Qxe5 18. Qxe5 Rd1+ 19. Kh2 Bd6! (trapping the white queen).

I thus gave up and peeked..

Apr-12-07  wals: A walk in the park but I missed out.Again. Damn, damn damn.

  fm avari viraf: It seems that Black is bursted in the opening itself. The Queen is totally cut off from the defense if 17...a6 then 18.Qxd7+ Kxd7 19.gxh5 & White is piece up. A nice instructive miniature.
Apr-04-08  rhudoris: 17.g4 ... Qxh3?? 18.Nxe5 what then??
18... a6?? 19. QxR mate
18... Ke7 19 Bg5+ f6 20 QxR mate
17.g4 a6? 18 Qxd7+ Kxd7 19 gxh4 f6
20 Be3 eog in any case W net a N for a pawn so no matter W answer they're caught
Apr-04-08  rhudoris: I meant no matter B answer of course!!
Apr-04-08  rhudoris: simsan wrote : 17. ... Qxe5 18. Qxe5 Rd1+ 19. Kh2 Bd6!

it seems to me that e5 is still a BPawn after g4 or did I miss sthg???

Nov-29-09  magnuschess: preparing for Nxe6!
Nov-14-10  sevenseaman: Polyvalent Knight huh! Its like the Sun, the center of our universe; its light falls on every visible point around.
