Jul-28-14		Phony Benoni: 1. Can White sacrifice his queen? 2. Is there a rook ready to pull a coup d'état on the back rank? 3. Execute program.

Jul-28-14		FSR: 25.Qxg7+ and mate in two more moves. First!

Jul-28-14		FSR: Damn you, <Phony>! :-)

Jul-28-14		M.Hassan: 25.Qxg7+ Rxg7 26.Rd8+ Rg8 27.R(any)xg8#

Jul-28-14		lost in space: I love Mondays 25. Qxg7+ Rxg7 26. Rd8+ Rg8 27. Rxg8#

Jul-28-14		lost in space: I think 25. Rd8 Qb1+ 26. Bd1 wins too. But far less elegant and forced.

Jul-28-14		dfcx: 25.Qxg7+ followed by 26.Rd8+. and Rxg8# Werner blundered with 24...Qf5. 24...Bd5 will allow him to survive longer.

Jul-28-14		Phony Benoni: <lost in space> 25.Rd8 Qxf6 does not work for White, Monday or no Monday.

Jul-28-14		M.Hassan: What do you think of 13...Bc5? I would have played 13....Rd8 leaving the Bishop on e7 for protection of f6 Knight: 13.........Rd8 14.Nf3 Nc6 15.e5 Ng5

Jul-28-14		Cheapo by the Dozen: Classic Monday. Took longer to load the web page than to solve.

Jul-28-14		Cheapo by the Dozen: Can Black survive if he does something different on Move 24? I'm thinking either 24 ... h5 or, if it turns out to matter whether White can get a rook to the back rank that's protected by the f6 queen, then 24 ... Bd5 25 Bxd5 exd5 26 Rc1 h5 Note that a simple Rh3 by White is inhibited by Black's threat of Qxg2#.

Jul-28-14		agb2002: The material is identical. Black threatens 25... Qxf6. The rook on g8 prevents Rd8+. Hence, 25.Qxg7+ Rxg7 26.Rd8+ Rg8 27.Rd(g)xg8#.

Jul-28-14		offramp: <M.Hassan> should always post after <FSR>. The avatars tell a story.

Jul-28-14		Once: It's a bit like Monty Python's lumberjack song... http://www.youtube.com/watch?v=sZa2... Whisper it quietly ... rooks secretly want to be knights. Sure, sure, we all know that rooks have this macho roughty toughty image. Everything is straight lines. North-South or East-West with none of this namby pamby diagonal nonsense. But the shameful truth about rooks is that they would dearly love to turn corners. They have this hidden fondness for the knight's "two forwards and one sideways" hop. It seems so free and airy ... not like the rugged armour and clothes that rooks normally have to wear. Don't believe me? Then take a look at this position, just after black has played 17...Rg6. click for larger view The Rd1 has slid along the back rank, but what he really wants to do is to swerve - swerve like a bird! So he plays 18. Rd3 intending Rg3 or Rh3. That's a knight-like tour of h1-f1-d1-d3-g3 (or h3). Be still my giddy heart! Fast forward to the position after 23...Rg8 click for larger view The black rooks are clearly not having a happy time. They can't turn corners easily. Instead they are forced into the stereotypical g file stuff. Boooring! Now white piles on the pressure with another rook-knight wannabe - 24. Rd1! The text books would say that this rook is grabbing the open file. Pah! What do they know? He really wants to liberate his inner girly by turning a few corners. This rook dreams of Rd8 <and then turning through 90 degrees to attack g8>. Rd1 isn't a straight line move. It's a part of a curve, a super swerve from a1 to g8 by way of the d file. And then our final POTD position. After 25. Qxg7+ Rxg7 26. Rd8+ Rg8 we get to here: click for larger view From here you might think that there are two equal routes to mate. Either rook can capture on g8 to give mate. Not so! 27. Rdxg8 would be plain and boring. A linear mate, all on the same line. It works, true, but only in the way that a pair of jeans work. Functional, staid, plain. What the position calls out for is another swerve, a little scrap of lace. 27. Rgxg8# is the way to go - allowing the second rook to turn a corner. Allow your rooks to access their inner knights. You know it's what they need.

Jul-28-14		Nick46: Awesome, I mean gruesome.

Jul-28-14		lost in space: <<Phony Benoni:> <lost in space> 25.Rd8 Qxf6 does not work for White, Monday or no Monday.> oops, right.

Jul-28-14		morfishine: 25.Qxg7+ forces mate Its funny how at times rooks are harried mercilessly by hungry enemy Bishops & Knights; yet at other times they move with blissful ease and powerful effect *****

Jul-28-14		Oxspawn: Monday morning. Slow brain. Distracted by the white bishop. But when in doubt, sac the queen. 25 Qxg7+ Rxg7 26. Rd8+ Rg8 27. R (take your pick )xg8# Not so hard but not “very easy” as some.

Jul-28-14		team kids can win: <Once: Sure, sure, we all know that rooks have this macho roughty toughty image. Everything is straight lines. North-South or East-West with none of this namby pamby diagonal nonsense. But the shameful truth about rooks is that they would dearly love to turn corners.

Don't believe me? Then take a look at this position, just after black has played 17...Rg6.> Rd1 could have asked the Nd4 to move out of the way too...a cool tactic was possible with Nxe6 threatening Rd8: <18.Nxe6 fxe6 19.Nf4 Rg5 (19..Rg7 20.Nxe6 Bxf2+ 21.Qxf2 Qxf2+ 22.Kxf2) Rd7) 20.Nxe6 Nc6 22.Rd7 Be7 23.Qf4 Rg6 24.Nc7 Nd4 25.Nxb6 Ne2+ 26.Kf1 Nxf4 27.Rxe7 Rg7 28.Rxg7 Kxg7> and White is 2p up. In the game continuation, <18.Rd3> Black was still in the game after fixing his back rank with <18...Nc6>

Jul-28-14		zb2cr: Monday, look for the ♕ sacrifice. Aha! Aha! I see it! 25. ♕xg7+, ♖xg7; 26. ♖d8+, ♖g8; 28. (either)♖xg8#.

Jul-28-14		Sally Simpson: Monday...How does that Boomtown Rats song go: "The Silicon chip inside my head won't switch to overload, All I have to do is sacrifice my Queen and away I go..." (repeat and fade)

Jul-28-14		Once: <team kids can win> Yes, that does look to be a stronger line. For the price of a knight, the black position comes under a lot of pressure, with weaknesses at e6 and d8. I do wonder though. 18. Nxe6 may be the line that silicon likes but a human would probably worry about the weaknesses that white is leaving in his own position, especially f2 and g2. With those vicious looking black bishops on adjacent diagonals, I think I'd like to keep the centre fairly closed and shuttle rooks across to the kingside. Sometimes we come across a position where computers spot a strong move that outwardly looks scary and few humans would play it. This may be one of those!

Jul-28-14		team kids can win: <Once> after <18.Rd3 Nc6> White has a lot of trouble playing for an advantage without the kind of serious tactical calculus you say White might want to avoid: <18.Rd3 Nc6 19.Nxc6 Qxc6 20.Rh3 Rg7> and now White has to really calculate. When I play it out, I tentatively get White keeping an advantage, but not gaining a winning endgame against accurate play. But even keeping the advantage is very tactical - e.g. <21.Qxf6 Qxe4> doesn't do it. The computer thinks that <21.Rc1 Qb6 22.Qxf6 Bd6 23.Rd3 Bxe4 24.Rd4 Bb7 25.Ng3 Qd8 26.Qxd8+ Rxd8 27.Rcd1 Bd5> is accurate and that White can eventually win an extra doubled pawn.

Jul-28-14		whiteshark: Dino got wernered with <25.Qxg7+>.

Jul-28-14		Penguincw: The lovely classic Monday puzzle! Just a queen sac and mate to follow.
