|Jan-18-10|| ||johnlspouge: Monday (Very Easy)
H G Cole vs A Tulip, 1946 (29.?)
White to play and win.
Material: B for N. The Black Kg8 has 3 legal moves, all dark squares on the back rank. A decisive stroke is possible with a forced sequence.
Candidates (29.): Rh8+
29.Rh8+ Kxh8 [Kg7 30.Qh6#]
30.Qh6+ Kg7 31.Qh7+ Kf7 32.Qf7#
|Jan-18-10|| ||TheaN: Monday 18 January 2010
Material: White up minor piece exchange, 2+ / +2
Candidates: Qh6, <[Rh8†]>
The first that flashed was Qh6, thinking that it would somehow force a Queen sac and with that a win. A matter of two seconds later I noticed that White win in this rather peculiar position with the sham sac:
<29.Rh8†!> and the game is over in three more moves. Or one, if Black decides:
<29....Kg7 30.Qh6‡ 1-0> that the White Rook is nothing worth to him. But, as said, the other way around doesn't work either.
<29....Kxh8 30.Qh6† Kg8 31.Qh7† Kf8 32.Qf7‡ 1-0> time to check how this weird position was reached.
|Jan-18-10|| ||zanshin: Pretty obvious if you know it's there - but still it must have been very satisfying to play <29.Rh8+>.|
|Jan-18-10|| ||DrGridlock: Interesting puzzle - since Black's position is so bad.|
Rh8 is mate in 4.
Be5, Bc2, Qh6 and Kg1 are mate in 6.
Nd4, Qe3, Qf4 are mate in 7.
Rh7, Bxd6, e5 are mate in 8.
Bd3 is mate in 9.
Qc1, Rh1, Rh6 Rh4 are mate in 10.
It's hard to find a continuation for White that does NOT lead to mate. I guess you only get full credit if you found the quickest mate.
|Jan-18-10|| ||chrisowen: The lightbulb goes on, plant the rook into the corner h8 and resistance of the black: Tulip withers and dies. He plays dum as, pair the rooks not those knights that stay men out on the rim after the early seeds of destruction are sown. Even 17..Qb5 leaves him with a triumph from the opening. Is'nt it strange how it blossoms for Harold after Qd8.|
|Jan-18-10|| ||VargPOD: Monday.
29.Rh8+ Kxh8 30.Qh6+ Kg8 31.Qh7+ Kf8 32.Qf7#
Total 1/1, 8,5/15.
|Jan-18-10|| ||Nullifidian: This is a *terrible* position. Almost every continuation leads to mate for White. White can even sacrifice his rook on h5 for no reason at all and still win, because the queen on the c1-h6 diagonal and the protected pawn on g6 ensure a classic queen and pawn mate.|
So 29. h6 is enough to force a resignation, but 29. h8+ xh8 30. h6+ g8 31. h7+ f8 32. f7# is fastest because it prevents spite checks.
I really must remember the tactic of cramming almost all my defending pieces into two files on the opposite side of the board from my king.
|Jan-18-10|| ||stacase: <Nullifidian> "I really must remember the tactic of cramming almost all my defending pieces into two files on the opposite side of the board from my king."|
Ha ha ha ha ha ha! Not my first chuckle of the day, but good enough to make note!
|Jan-18-10|| ||cyclon: 29.Rh8+ Kxh8 ( -Kg7 30.Qh6X) 30.Qh6+ Kg8 31.Qh7+ Kf8 32.Qf7X.|

Thanks for defending my favorite word, <zb2cr>.
Nowadays, one has so many opportunities to use it that gratuitous use is entirely unnecessary.
|Jan-18-10|| ||JG27Pyth: Open h files just scream rook sac, don't they?... easy & fun...|
This made me laugh:
<Nowadays, one has so many opportunities to use it [meretricious] that gratuitous use is entirely unnecessary.>
As usual Johnlspouge's analysis is quite accurate! ;)
|Jan-18-10|| ||turbo231: I chose the wrong line Qh6 and still mated rybka in 8 moves. The proper line rh8+ would have mated in 4 moves. I saw i could mate in 8 moves, but i failed to see the mate in 4 moves! Go figure.|
|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+.)|
