|Jan-18-10|| ||lightbishop c5e6: Got it, its mate in four with 29. Rh8+! Kxh8(... Kg7 30. Qh6#) 30. Qh6+ Kg8 31. Qh7+ Kf8 32. Qf7#. Quite easy, even for a monday.|
|Jan-18-10|| ||WhiteRook48: 29 Qh6 also wins but not as quickly|
|Jan-18-10|| ||Once: All the best books say that rooks need open files to work on. But what rooks really need are open files with entry points that allow them to attack something.|
The truth, I guess, is that many rook attacks are really L-shaped. Today, the Rh2 goes to h8 to attack g8. And all to decoy the black king to a square where white's queen arrives with check. Then Qh7+ and Qf7# as the queen plays hopscotch with the focal points in front of black's king.
Simple enough, we all say, but you would be amazed how many regular chess players wouldn't see Rh8 without the assistance of satnav.
|Jan-18-10|| ||turbo231: <Once> Please excuse my ignorance but what is satnav?|
|Jan-18-10|| ||turbo231: <Once> You wouldn't be talking about a satellite navigation would you. Well i resemble that, along with a scout,search party, and a 100 man posse!|
|Jan-18-10|| ||YouRang: A good example of making the best use of time.
Sac a rook to buy "just" 1 tempo, namely by making it possible to bring our Q to h6 *with check*. Meanwhile, black has no time to do anything about it. 28.Rh8+! Kxh8 29.Qh6+ Kg8 Qh7+ 30.Kf8 Qf7#
|Jan-18-10|| ||Once: <turbo231> Indeed, a satellite navigation device. According to the Once definition of modern life: an electronic instrument designed to insert unfeasibly large vehicles into ridiculously small roads.|
|Jan-18-10|| ||patzer2: For today's Monday puzzle solution, 29. Rh8+! initiates mate-in-four.|
|Jan-18-10|| ||TheFocus: Today, I took two seconds to find the answer. Maybe, tomorrow (gasp), I may try a Tuesday puzzle.|
|Jan-18-10|| ||felixd: This makes me remember the Damiano's mate...
I wish I could have such an opportunity in one of my games.
|Jan-18-10|| ||zb2cr: <johnlspouge>,
You're quite welcome.
|Jan-19-10|| ||kevin86: Black's king is forced to move and lethal checks will follow.|
|Jan-19-10|| ||al wazir: Apologies to those who think I was trolling or that I don't know what a meretrix is. I was trying to make a case for the move I chose. (I didn't see Rh8+.)|
|Nov-01-14|| ||perfidious: <jls: Nowadays, one has so many opportunities to use (the word meretricious) that gratuitous use is entirely unnecessary.>|
|Nov-10-17|| ||offramp: Today, tulips. Tomorrow, poppies.|
|Nov-10-17|| ||goodevans: <22.Rh7+ Kxg6 23.e5+> just begs to be looked at and it doesn't take long to work out that it wins quite quickly with less opportunity for resistance than 22.Rh2 allows.|
|Nov-10-17|| ||thegoodanarchist: Tulip got a lump of Cole for Christmas!|
|Nov-10-17|| ||Elrathia Kingi: Interesting game, but I wouldn't recommend this variation for white. Black went wrong with 16...Qa5 -- it wasn't necessarily a bad move (stockfish likes it), but it was a wrong idea. The correct followup was either to protect the queen by b6 or defang the pin by Nb6. Because black didn't see the correct followup, he should never have played Qa5, and perhaps Bg4 to stop all of the pawns would have been a better choice. |
The objective blunder was playing f6 -- after this, White's attack is irresistible.

5.0 minute analysis by Stockfish 8
|Nov-10-17|| ||Breunor: Stockfish indicates that black goes wrong with 17 ...Qd8. It rates 17 ...Nb6 as -1.79 but 17 ...Qd8 as +1.94, more than a 3.5 value swing. |
Interesting, it looks like the idea on keeping the queen at a5 is to play Bb5 and then invade d3; with the black queen on a5, the white queen on d2 is pinned and can't defend the square (d3).
This looks pretty subtle to me!
