|Jun-01-10|| ||englishdave250: First I looked at B-d7, but soon rejected it, this one took a few seconds longer to find|
|Jun-01-10|| ||TheaN: Tuesday 1 June 2010
Material: White up unbalanced, ♘ vs 2♙
Candidates: Bf6, Be7, Ne4, <[Rxd4]>
From a Tuesday puzzle I would have expected Bf6 to work but it doesn't. Only after a minute or so I noticed White is up a piece for two pawns. This highly suggested some sham sac to win either another piece or one or two pawns back. In fact, White forces both.
<33.Rxd4!> abuses the paralyzed Black pieces. Rd6 defends f6 (Bf6) and Re8 defends g8 (Bf6 with Rg8). Now White sham sacs the Rook on g4 to attack the Bishop on c4 (defending against the killer Ne4 with Bd5) and the Rook on d6.
<33....Rxd4 34.Bf6 1-0> is obviously not possible.
<33....Ree6> possible because a Rook left the g-file, but:
<34.Rxc4 > it just loses the Bishop. Possibly the best try is:
<33....Rc6> defending the Bishop and moving the Rook, but alas the Rook is still overworked, so the Bishop is not defended at all.
<34.Rxc4 > time to check.
|Jun-01-10|| ||TheaN: <dzechiel: Well, now I know who David Moody is! Our own Phony Benoni! I'm sure I read his bio years ago but forgot the proper name. Too bad he's on the short end of this game.>|
The fact that <tpstar> is Tony Palmer makes this even better: a CG members game. Although, in expectation we all play reasonable chess, this probably happened in more games on this server.

I can guarantee that none of my games are on here! (Oh the shame!)
Got today's puzzle though.
|Jun-01-10|| ||zb2cr: <Once>,
That was hilarious!
I found this one as soon as I stopped looking for a quick mate.
|Jun-01-10|| ||TheaN: <Once>
For the mere mortals among us: he missed it.
|Jun-01-10|| ||CHESSTTCAMPS: In this opposite-colored bishops position, white has a knight for two pawns and major pressure on the black king trapped in the corner. Black threatens dxc3 and the knight can't leave its post without allowing black to turn the tables with 33...Bd5(+) (assuming that black avoids the trap 33.Ne4?? Rxe4?? 34.Bf6+ forcing mate). White has an economical solution to deal with the upstart d-pawn:|
33.Rxd4 and now black must lose at least another piece to delay mate.
A) 33...Rxd4 34.Bf6#
B) 33...Rc6(or other Rd6 moves) 34.Rxc4
C) 33...B moves (or Rc8) 34.Rxd6
Black likely resigns immediately.
|Jun-01-10|| ||johnlspouge: Tuesday (Easy)
T Palmer vs D Moody, 1999 (33.?)
White to play and win.
Material: N for B+2P. The Black Kh8 has 1 legal move, g8, x-rayed by the White battery Rg1 and Rg4. The battery is masked by Bg5, suggesting a discovered attack or clearance. The Black Rd6 has the absolute burden of preventing Bg5-f6#. The White Kh1 is vulnerable to Bc4-d5+.
Candidates (33.): Rxd4
33.Rxd4 (threatening 34.Rxd6 or 34.Rxc4)
Rc6 [Bd5 34.Rxd5] [else, Black drops a piece]
The Black Rc6 is burdened with preventing Bg5-f6# and cannot recapture.
|Jun-01-10|| ||M.Hassan: "Easy" category, white is up in material.I do not see a checkmate in here,but I think the game could have continued as follows:
34.Rxc4 and white ends up in further material gain.
|Jun-01-10|| ||jsheedy: 33. Ne4 seems to work. Let's check....Hm, guess not.|
|Jun-01-10|| ||patzer2: The discovered attack 33. Rxd4! solves today's Tuesday puzzle.|
Earlier 28. Nxg7! Bxg7 29. Rag1 illustrates a basic pinning combination -- sham sac to create the pin and then pile on the pinned piece to win it.
|Jun-01-10|| ||chrisowen: Key is locking down the rook. Palm off Rxd4 does again a handy turn. Of the Wormald avid mood 6.c4 squashing counterplay. It was light's piloting 27.Nh5 torching gradual g7 picking the defence. Why alencon the hung queen 23.Qxh4 when TP looks to lace up the pretty finish?|
|Jun-01-10|| ||kevin86: I missed this one-but it WAS not a Monday.|
|Jun-01-10|| ||gawain: 33 Rxd4 is unanswerable.
More subtle than usual for a Tuesday puzzle.
|Jun-01-10|| ||Jimfromprovidence: It's a nice touch to see games played by long-time members used as puzzles. |
Loved 32 Bg5, threatening Bf6#.

That move won the rook. The puzzle move was the necessary follow-up.
Also liked that 31...dxc3 was unplayable for black because of 32 Bxc3+, with mate to follow.

Very nice game by <tpstar>.
|Jun-01-10|| ||YouRang: About right for a Tuesday, IMO. White would have mate with Bf6+, except that the 6th rank is guarded by black's rook on e6. This means that this rook is tied to the 6th rank, so we needn't fear its influence on the e-file. |
With this in mind, we see that 33.Rxd4 at once wins a pawn, threatens to take black's defending rook, and it threatens to take the bishop.
It doesn't take long to see that black is hosed. There is no saving the bishop (e.g. 33...Rc6? 34.Rxc4!; 33...Bd5? 34.Rxd5!)
Black's best try might be the dippy swindle attempt: 33...Be2!? hoping for 34.Rxd6? Bf3+ 35.Rg2 Re1#. But if 33...Nxe2, black can resign with a little chuckle.
|Jun-01-10|| ||tpstar: Morphy Mates = Nimzowitsch vs B Nielsen, 1930|
Pillsbury Mates = Anderssen vs B Suhle, 1860
Black was the longtime editor of "Michigan Chess" magazine, while White is the longtime Quiz contributor.
|Jun-01-10|| ||doubledrooks: <Once> : Great stuff today.|
As for the puzzle, 33. Rxd4 brings home the point.
|Jun-01-10|| ||YouRang: I see that I botched my post above, confusing the d & e files. Hopefully nobody is going crazy trying to figure it out. :-\|
|Jun-01-10|| ||TheBish: T Palmer vs D Moody, 1999|
White to play (33.?) "Easy"
33. Rxd4! wins instantly, for example 33...Rxd4 34. Bf6#, or 33...Rc6 34. Rxc4, winning a piece.
|Jun-01-10|| ||wals: I did not even see it!!!
Rybka 3 1-cpu: 3071mb hash: depth 17:
An even game up to move 22, then,
BLACK, a Bishop and three pawns, for two Knights, blunders,
+2.31 22...Qh4. better,
1. (0.30): 22...Qe6 23.Nf4 Qe5 24.Be3 Bg5 25.Rad1 Rad8 26.Rxg5 Qxg5 27.Ne6 Qg4 28.Nxd8 Rxd8 29.Qf4 Qxf4 30.Bxf4 d5 31.exd5 Bxd5+ 32.Kg1 f6 33.Kf2 Kf7 34.b4
WHITE, looks obvious, doesn't it,
-0.16 23.Qxh4. however, better was,
1. (2.31): 23.Qd4 Bf6 24.Qxc4 d5 25.Qb4 d4 26.Raf1 dxc3 27.Rf4 Qh6 28.Bxc3 Bxc3 29.Qxc3 Re6 30.Nc5 Rg6 31.Rgf1 Qg5 32.Qc2 f6 33.Nxb7 h6 34.Nc5 Kh7 35.Rf5 Qe3
Next major error,
BLACK, material,Bishop and three pawns for two Knights.
+1.90 27...Be5. better,
1. (0.71): 27...Re6 28.Rag1 g6 29.Nxf6+ Rxf6 30.Rd4 Rb6 31.Rb1 Rd8 32.Bf4 Rb4 33.Bc7 Rd7 34.Be5 f5
Black made certain of a White win with,
+6.99 31...Rad8. better b5 or f6 @ +3.20.
|Jun-01-10|| ||A Karpov Fan: got it|
|Jun-01-10|| ||turbo231: missed it|
|Jun-01-10|| ||cjgone: Got this one but not Mondays.. I'm feeling a little more confident to start these puzzles again after being discouraged for like 2 weeks.|
