  johnlspouge: I should have consider the defense after 23.Rxd8, and I should have.
Jul-20-09  jsheedy: 21. Qxc5 seems simplest. (21. Bxf7+ transposes.) If 21...Nxc5, 22. Bxf7+, Kxf7, 23. Rxd8 nets white a rook.
Jul-20-09  ZUGZWANG67: Discovered attack enhanced by a pin: 21.Qxc5 Nxc5 22.Bxf7+ Kxf7 23.Rxd8
Jul-20-09  PinnedPiece: Pretty clever little combo for a Monday.
Jul-20-09  Patriot: I saw the combination quicker than I could count material. I just didn't realize that white is down a piece in the starting position.

Anyway I spent more time trying to see if I was missing something between two possible solutions: Bxf7+ or Qxc5 first? Apparently both work.

Hmmm... Today, I was obviously more concerned about getting the kids out the door to their summer camp than I thought :)

Jul-20-09  Patriot: <johnlspouge> Geeze, man. Where's your priorities?! :-)
Jul-20-09  ZUGZWANG67: Hm. I get only half the point because I didn' t consider 23. ...Nd7.

  playground player: It seems a lot of us (including me) didn't notice White was a piece down, so compelling was Qxc5. You look at the board and that's what you see. But it's a good lesson: unless you're pressed for time, ALWAYS look before you leap. If you're playing the game, of course, you'll know you're a piece down--but it never hurts to take the time to case the scene before you move.
Jul-20-09  sileps: 21.Qxc5 wins the exchange after 21..Nxd5 22.Bxf7+ ..Kxf7 23.Rxd8. I was surprised to see a non-definitive ending in a monday puzzle. As in checkmate-definitive.

  kevin86: White picks up a rook and goes an exchange up...

21 ♕xc5-removing the queen's shield-♘xc5 22 ♗xf7 double attack of king and queen ♔xf7 23 ♖xd8.

Easy,but a little deep for a Monday puzzle.

Jul-20-09  Marmot PFL: Pretty simple since 21 Bxf7+ is an alternative to Qxc5 and the same position is reached. Black could have put up tougher resistance.
Jul-20-09  YouRang: I saw the queen-winning discovered check potential right away, if only we can get rid of that knight on d7.

And that's easy since the knight is guarding the rook which is attacked by our queen.

So, 21.Qxc5 Nxc5, giving us our discovered check, 22.Bxf7+ Kxf7 23.Rxd8 winning the queen back, a rook to the good.

The continuation is worth noting: 23...Nd7!? attempting to trap the rook, but white gets out of that with 24.Rd1!, threatening the knight and ultimately taking advantage of the fact that black's bishop is pinned to the rook on a1.

Nice Monday puzzle. :-)

Jul-20-09  waustad: Has the Goglidze Attack ever been played in a game in Japan? It might lead to a good pun.
Jul-20-09  310metaltrader: i think black is ok after Ne6.
Jul-20-09  gauer: Jamin Gluckie comments about the game here: theratwhowouldbeking.blogspot.com & 5 or 6 years ago near U of S, he helped restart the Saskatoon club & Saskatchewan Chess Association. A search lately might help one find a ring of other Canuck chess bloggers.
Jul-20-09  kingfu: Easy or not , I am taking it! I got one for a change. In this Canadian Open, I notice that the higher rated players are winning in around 20 moves, game after game after game. And you see fairly high rated players with a bunch of undeveloped pieces or pawn grabbing or their King in the middle of the board. It is been very entertaining and instructive on how not to open a game against a higher rated player. Gluckie is 300 points above Mario.
Jul-20-09  randomsac: Nailed it, because the knight is effectively pinned because of a discovery by the bishop.
Jul-20-09  gerpm: Always enjoy Monday
Jul-20-09  amolv: Could someone explain to me why not 21. Bxf7 22. Qxc5?
Jul-20-09  DarthStapler: Got it
Jul-20-09  Dredge Rivers: But don't want it!
Jul-20-09  seagull1756: Oh my god, there are 1700-rated players in this database?!?!?!?!!?
Jul-20-09  muralman: I got this one, but it was a very unsatisfying Monday puzzle because the end brought on only an imbalance, a gray area.
Jul-22-09  jgluckie: It's great to see so many people kibitzing about my game. To answer a couple of questions: there is no difference between Bxf7+ and Qxc5 as both would likely transpose to the game continuation. My opponent could have put up more resistance with Ne6 instead of Nd7, and that endgame would require a bit of technique for white to win.

17...Nd7 was an unexpected move (and probably not the strongest continuation), and I had to see the queen-sac combination before playing my 18th move. It's not that hard to see, though :-)

Anyway, I enjoyed reading these comments. Thanks for posting.
