|May-31-10|| ||patzer2: Monday is a good day to sac the queen for a mate-in-two, as with today's puzzle solution 31...Qxg2+! 32. Nxg2 Rh3#.|
|May-31-10|| ||agb2002: <johnlspouge: Monday (Very Easy) |
Anderssen vs J Finch, 1851 (31...?)
Black to play and win.
Material: 2B+2P for R+N. The White Kh1 has 1 legal move, h2, x-rayed by the Black Qf2. Black has an overwhelming material superiority, suggesting a sacrificial attack. As Garfield says, “Es muss Montag sein,” or was it "I love Mondays!"?
This reminds me of David Hilbert's epitaph (on his tombstone):
"Wir müssen wissen.
Wir werden wissen."
|May-31-10|| ||backyard pawn: Oh. First, I solved it, having slept in this morning, thinking today was Sunday. Very happy and confused why I would have had such an easy time with any puzzle at the end of the week. Then, of course, I realized that today is a Monday holiday, and I'm trying to buoy my spirits for at least solving the Monday puzzle, even though it is a terrible disappointment.|
|May-31-10|| ||turbo231: I should never try to solve these puzzles on my laptop lying in bed after just waking up and before drinking coffee.|

Hi, <Antonio>. I thank you for enlightening me. Quite in character, Hilbert's epitaph carries to infinite extremes the saying, "If only I knew then, what I know now."
|May-31-10|| ||chrisowen: Eg Finch has a passer in ease you are opening g2 the bees knees. We dish up the queen takes hard rock then rook over gives it a knock. You see doubt white pecking honeybun as countdown's long since begun. Shoot chaff Rh3 sting in the tail missing 19.Qg3 put him in jail.|
|May-31-10|| ||gawain: Oh, I see! 31...Qxg2+ knight takes then 32...Rh3#
Took me a minute or two. I wasted time looking at Rh3+ as the first move.
|May-31-10|| ||apiana: Qg1# Rxg1 Rh3 mate does the trick too|
|May-31-10|| ||Arbiter58: <apiana: Qg1# Rxg1 Rh3 mate does the trick too> apart from the fact that gxh3 takes the 'mating' rook and white wins :)|
|May-31-10|| ||SufferingBruin: I'm sorry but it's been months since I've written this and it really needs to said again.|
If I could write like <Once>, I'd never leave the keyboard. Praise is not always comfortable to receive but he's just going to have to take it for now. That is all.
|May-31-10|| ||Domdaniel: This is so easy I solved it last Saturday. "Monday, Queen sac, mate in 2" were my words, as I recall.|
Time taken: minus 48 hours.
|May-31-10|| ||scormus: Didn't get this :-(
Kept looking for the damn stalemate .....
|May-31-10|| ||gofer: Ah, back to the normal weekly routine, a queen sac on a Monday. |
31 ... Qxg2+ 32 Nxg2 (forced) Rh3#
I imagine there will be few complaints about this one! Time to check...
|May-31-10|| ||A Karpov Fan: got it (i think this Ba5 retreat is strong against the evans gambit, I play it myself)|
|May-31-10|| ||David2009: Missed it! 31...Rh3+?? 32.gxh3 Bd5+ 33.Re4 1-0. Impulsiveness comes before a fall.|
|May-31-10|| ||lzromeu: 29.NH4 was losing move|

Wissen ist Macht. Nichts wissen macht nichts.
|May-31-10|| ||M.Hassan: <kellomo: In your line after 32.Rg1, then Rh3 is mate> Thank you so much!! To be quite honest, I did not see it!!!like I did,nt see the two move mate at first.Appreciate it|
|May-31-10|| ||Domdaniel: <Izromeu> -- < 29.NH4 was losing move> It sure looks like it (at first I couldn't see why Anderssen, with his mania for attacking, didn't just play 29.Rxe6) -- but in fact White is already totally lost. Perhaps he intended 29.Rxe6 (when ...fxe6 gives him chances) before noticing that it lost at once to 29...Qxf3!, when both the f and g-pawns are pinned and mate soon follows. White can try 30.Rxh6+ but runs out of juice after 30...Kxh6 31.Qh8+ Kg5 32.Qe5+ Kh4 and Black wins.|
In fact both players missed tactics a little earlier, but White had been in a worse position since the opening. His decision to give up the LCB on c4 was mysterious, given its attacking powers, and the e5 advance was naive. Black could have punished him with an earlier ...Qd3, eg on move 15 when the Knight is unguarded on c3.
Typical of Anderssen, the whole idea of h5, B-for-N exchange on e7, and Nf6?! is very ingenious, but unsound. Black could have improved with 25...Qf5 instead of ...gxf6. Even after 25...gxf6, both players missed an important twist: White doesn't have to play 26.exf6 (threatening fxe7 and Qg7#) at once -- the Zwischenzug 26.Rad1 is better. After 26.Rad1 Qxd1 27.exf6 Bxf2+ 28.Qxf2 Red7 29.Rxd1 Rxd1+ 30.Kh2 Black is still better thanks to the mate threat, but black has two rooks for the queen, and some counterplay.
White did admittedly have a better move than either 29.Rxe6? or 29.Nh4?! -- after 29.Kh2 he's still alive, but Black has 29...Rxf3, which should win, even after 30.Rxe6 Rf5! -- when f7 is covered and one of the white pawns (f2 or h5) will fall with check.
Anderssen played the whole game poorly. If it wasn't for the fact that Black let him back into it two or three times, one would think it was the Black player who was a famous master.
|May-31-10|| ||apiana: missed that right, lol|
|May-31-10|| ||David2009: This is an example of an Anderssen attack that nearly but not quite breaks through. Rewind to move 27:

Black has just played the excellent Rd8-g8! Setting this position up on CraftyEGT,
we find by trial and error that the game line gives best White
chances until move 29 (e.g. 28. Qxg8+ Kxg8 29. fxe7 Qd7! leaves Black ahead on material). 29 Nh4? seems to be a decisive mistake: instead
29.Kh2 Bxf2 30.Rxe6 fxe6 31.Qxe6 hangs on. One possible continuation (Crafty playing Black) is 31... Rg7 32.Rc1 Bg3+ 33.Kh1 b5 34.Nd2!
and White may just be holding on: e.g. 34...Qd8 35.Nf3 Qd3 36.Nd2 repeats, or 34...b4 35 Ne4 threatening Nf6+ with counter-play.
|May-31-10|| ||scormus: <Domdaniel> I thought the same - about W giving up his KB as well as his 29 Nh4 (what an ugly move!) It must have been bitter to be on the receiving end of so much radiation from B's DSB. It would have saved B if W played 32 Qg7+ instead of Qe5+ in your line. |
It is painful to see such a great player as Andersson playing such a terrible game - maybe he'd been indulging in the Absinthe they probably dispensed there.
|May-31-10|| ||wals: Of course, so easy, and I dipped out.

Black to play (31...?) "Very Easy"
Candidate moves: Bd5, Rg5, Qxg2+
There appear to be several winning moves, including 31...Bd5 (threatening both Bxg2+ and Rh3#), 31...Rg5 (threatening Qxh4# and pretty much forcing White to throw in the kitchen sink to stop mate), but my choice here (which I didn't see for quite awhile) is...
31...Qxg2+! 32. Nxg2 Rh3#.
The queen sacs start early this week!
