Jul-30-12  Jim Bartle: Ootes, he did it again.
Jul-30-12  andyatchess: Why did he sac the horse? Irrelevant anyway I guess.

Wishes for a creative week!

Jul-30-12  GordonL: Just for a bit of fun can anyone see a defense to 30.Qxe6..?
Jul-30-12  zb2cr: Very easy indeed. 30. Qxg7+, Rxg7; 31. Rxg7+, Kh8; 32. Rh7#.
Jul-30-12  dragon player: It's monday, so a queen sac:

30.Qxg7+ Rxg7
31.Rxg7+ Kh8
32.Rh7#

Time to check.

Yes right, and it's a game from Holland. Always nice.

Jul-30-12  David2009: L Ootes vs K Yamada, 2011 White 30?

30.Qxg7+ etc. mates in three.
===
Playing through the game, 27...Rcf7? (interfering with the defence of the Ng6) triggered the disaster:


click for larger view

(OOtes vs Yamada 2011 28?). Now 28.g4 wins, since the thematic line block f4 leaves the Ng6 en prise.

Setting the position up in Crafty End Game Trainer (link http://www.chessvideos.tv/endgame-t...), the resilient robot fights on with 28...Qe7 29.gxf5 Rxf5 30.Bxf5 Rxf5 31.Rxg6 Bxg6 32.Rxg6 Kh7 when 33.Qg2 holds on to the material and wins. Enjoy finishing the robot off!

Here's a further Crafty EGT link to the position at move 27: http://www.chessvideos.tv/endgame-t... Against the game line 27.Be1 the resourceful robot finds 27...Qg5! foiling line opening, when finding the win (unaided by silicon) is outside my pay grade. Any takers?

Jul-30-12  TomOhio: With just a cursory look, I think

29.... Nce7
would have been much better. The Knight on g is lost at this point, but at least this keeps the White Bishop from seeing h7 and saves the game, at least for now.

Then,
30. Bxg6 Nxg6
31. Qxg6 Rd7
32. Qxh6 Rff7
33. Bh4 Qc7
34. Nf4
threatening the Black e-pawn and, after Bf6, an indefensible fifth attack on g7.

34. ... Rxf4
35. Qxf4 Bh5
Black is down significant material but the White Queen is at least partially occupied now with the f-pawn.

  Oxspawn: Mondays seem to come around quicker and the problems also seem quicker to solve. This is another one where you just keep bashing away. I think solving time was around 15 seconds and most of that was looking for the trap. (Didn’t find one.)

30 Qxg7+ Rxg7
31 Rxg7+ Kh8
32 Rh7++ Oh!
Presumably Yamada had overlooked the protection of white bishop or thought that the knight fork would relieve the pressure. But all the black moves are forced and there is no opportunity to intervene. Interesting for all the firepower black has clustered around that area of the board, there is only one piece protecting the pawn on g7. The queen and other rook can only watch out of the corner of the eye as their ‘dear leader’ comes to a sorry end.

  kevin86: A quick battering mate by the two rooks (and bishop).

Tripled major pieces make one heck of a convoy.

  chrisowen: Clomping down gfile in conger eel processin Alekhine gun 'so get

your egg crashed by my hells wind staff' force in whale, fluke dives

on g7 Rxg7 Rxg7+ king sidestep to h8 it rook heading off h7#

Jul-30-12  A.G. Argent: <...loaded the gun...> Remember the scene in The Birds when the crows slowly mustered in the schoolyard? Granted, Yamada was a bit gummed up but he was too slow dealing with the coming murder. 27...Rff7 woulda helped buttress a bit and afford an escape hatch to f8 but he was pretty much terminal by then, weren't he.
Jul-30-12  lzromeu: The monday's queen sac strikes again.
I love this
The puzzle 1 round before would be very interesting too.
Jul-30-12  Crispy Seagull: A forced mate in three:

Qxg7+ Rxg7
Rxg7+ Kh8
Rh7#

Looks like the trouble started as early as move 7 for black with f5. That and 27...Rcf7, loosening the knight and making 28...f4 impossible.

Jul-30-12  e4 resigns: These mondays usually take 6-10 seconds for me to figure out. Anything that sacs the queen makes me happy.
Jul-30-12  YetAnotherAmateur: <GordonL> 30. Qxe6 Qf6 If white presses the attack with, say, 31. Rxg7+ Qxg7 32. Rxg7+ Kxg7 33. dxe5 and black is down a piece. Qxf6 is met by Rxf6.

Basically, no point in passing up an easy mate in 3 for that.

  agb2002: White has the bishop pair for a bishop, a knight and a pawn.

Black threatens 30... Nxg4.

Pattern recognition finds quickly 30.Qxg7+ Rxg7 31.Rxg7 Kh8 32.Rh7#, without even paying attention to dxe5.

Jul-30-12  Abdel Irada: <Once>:

Agreed. This is why I try to develop all of my heavy pieces on the i-file.

Jul-30-12  tivrfoa: hmm... like we have very difficult and insane, there must be very easy and cakewalk or piece of cake. Today was piece of cake. But there's not enough days in the week ... :)
Jul-30-12  smirnoff: <GordonL: Just for a bit of fun can anyone see a defense to 30.Qxe6..? >

No. However, Houdini(20) suggests this line to be least sadistic: 30...Qg5 31.Rxg5 hxg5 32.dxe5 Bd7 33.Qg6 Bf5 34.Qxc6 Bxd3 35.cxd3 g4.......

Jul-30-12  gars: Praise the Lord for Mondays!

  PhilFeeley: If it's Monday, there has to be a queen sac! 1. Qxg7+! Rxg7 2. Rxg7+ Kh8 3. Rxh7#
Jul-31-12  TheBish: L Ootes vs K Yamada, 2011

White to play (30.?) "Very Easy"

Maybe have time to submit this "under the wire", but now 12:01 EDT, so it's officially Tuesday now.

30. Qxg7+! Rxg7 31. Rxg7+ Kh8 32. Rh7#.

The queen sac comes early this week! Pretty simple mate in 3. Anytime you have a triple battery, you can expect good things!
