|Oct-14-08|| ||agb2002: <AniamL: <MAJ> Tricky, tricky. Maybe I should go to bed :)> I also overlooked 30.Qxe2 in reply to 29... Re2 :(|
Fortunately, it would have been my last option :)
|Oct-14-08|| ||zb2cr: Looks like the only way to win is 29. ... Qg2+; 30. Rxg2 (forced), fxg2+; 31. Kxg2, Bxd1. Black is up by R vs. P. |
One thing I note is that if Black tries to slowly build the attack by 29. ... Re2, White calmly plays 30. Qxe2! The White Queen can't be taken because of 31. Rf8#.
|Oct-14-08|| ||ahmadov: <EmperorAtahualpa: <chessgames.com> I recommend this game as a Tuesday (perhaps Wednesday) puzzle.> <CG> waited 2 and half years to listen to this recommendation...|
|Oct-14-08|| ||ahmadov: By the way, I solved it very quickly...|
|Oct-14-08|| ||gtgloner: Got this one pretty quick. 29. ... Qg2+ forces exchange of queens and loss of rook for white.|
|Oct-14-08|| ||chrisowen: Joseph plays 18..Qh4!? looking to mix it with a spritely f-pawn storm. G3 cordially cheers Blackburne whilst Qd1 is a lemon and Emil naturally gets squashed.|
|Oct-14-08|| ||ThePawnOTron2: I got this one pretty quickly. 29...Qg2+! decoys the rook on to a square where it can be captured with check, discovers an attack on the d1-queen.|
|Oct-14-08|| ||TheaN: 2/2
Not very hard, but it seems to be a shamsac-non-mate week thus far. Those kind of positions, where mate might be a possible goal but is not, are usually a bit more difficult. This puzzle, whatsoever, is an easy Tuesday.
White: b4, c4, d4, g3, h2, Nd2, Ba1, Rf2, Qd1, Kh1
Black: b7, c6, f3, g7, h7, Bb6, Bg4, Re8, Qh3, Kh8
Material: = (-vs)
Candidates: Re1, <[Qg2]>
Trying Re1 is plausible, seeing the extremely threatening circumstances around the White King. Nonetheless, Re1 would only meet Qxe1 with no real take-out-the-defender goal for Black to boot. Black would want to control g2, but already controls it twice. The King couldn't take on g2 with a possible check, and then the discover of the Bg4, Pf3 and the White Qd1 becomes visible, and the solution is fact and extremely easy.
<29....Qg2 30.Rxg2 fxg2> and the discovery worked perfectly.
<31.Kxg2> not taking g2 does not gain anything extra at all for White, but...
<31....Bxd1 > and the game is simply over for White having lost a for .
|Oct-14-08|| ||johnlspouge: Tuesday (Easy):
E Schallopp vs Blackburne, 1886 (29
Black to play and win.
Material: B for N. The White Kh1 has 1 legal move. The Black Pf3, Bg4, and Qh3 dominate the light squares around Kh1, but White has serious threats on Pf3. The Black Bb6 has aim on g1, the only flight square of Kh1, but Pd4 blocks the a7-g1 diagonal. The Black Re8 has an open file and the 2-nd rank is ripe for invasion. The Black Kh8 is potentially vulnerable to back-rank mates. No candidate is immediately obvious, so an examination of checks, captures, and threats is in order.
Qg2+ 30.Rxg2 fxg2+
and after 31
Bxd1, Black has R+B for N+P.
|Oct-14-08|| ||Patriot: I saw 29...Qg2+ 30.Rxg2 fxg2+ 31.Kxg2 Bxd1 immediately and looked no further.|
29...Re2 is something I never considered here, because Qg2+ is so forcing by comparison. I tend to stay away from lines that aren't completely forcing if a forced win exists because it leaves your opponent with too many options. In this case 30.Qxe2! is a killer. I'm not saying it isn't worth considering. It's ok to consider if you have plenty of time on the clock and you think it is winning even more material or a possible mate exists. But less forcing moves require more care simply because your opponent has more options and that leaves you with a greater chance of making a mistake during analysis.

and black cannot take the Q because of Rf8#>
tricky indeed! i fell victim to the Re2 move as well.
|Oct-14-08|| ||fouard: Got to be Qg2+, as 30 Rxg2 fxg2+ 31 Kxg2 wins back the queen with 50% interest, and the knight is coming off next.|
|Oct-14-08|| ||YouRang: This came together for me pretty quickly. Everything is nicely forced to pick up a rook for a pawn (and take off queens as a bonus) using a discovered attack with check.|
The only thing sort of unusual is that the move which uncovered the attack with check was a capturing pawn.
|Oct-14-08|| ||Kasputin: Black can win a rook through this forced sequence:
30. Rxg2 fxg2+
And next move black will play ...Bxd1. Black will have a large material advantage (up by a rook - less a pawn if white plays 31. Kxg2) and should have no problems winning. Probably white resigned at some point during this sequence. Time to check.
|Oct-14-08|| ||kevin86: Black sacs the queen to gain a rook and the queen back after a double attack.|
30 xg2 fxg2+ 31 xg2 xd1
|Oct-14-08|| ||JG27Pyth: aaahhh -- here's a position from a current game of mine with a very similar tactical theme but in my case played as a blunder: |

I'm white and I play 13.Qxg7+!? here
Kxg7 2.e6+ f6 3.exd7 Bg3+ and now I've got problems... I lose the right to castle, he owns f2 and can make my whole kingside quite awkward and Nb4 looks very troublesome too. imo. This is an ongoing correspondence game and we're only a half-dozen moves down the line from here, so <no help please.>
|Oct-14-08|| ||WarmasterKron: Quite easy once I stopped looking for mate.|
|Oct-14-08|| ||kirchhoff: <Puffen:> Here's yesterday's puzzle. Your playing move 26. as White.|

|Oct-14-08|| ||brainzugzwang: Surprised there hasn't been more comment on what a horrific blunder Schallop made with 29.Qd1?? 29.Qb1 is kind of an ugly defensive move, but how does Black proceed from there?|

Hi, <wals>. It's nice to see you back - thanks for the link.
|Oct-14-08|| ||johnlspouge: < <JG27Pyth> wrote: aaahhh -- here's a position from a current game of mine with a very similar tactical theme but in my case played as a blunder>|
Too few of us engage in such realistic self-appraisal, <JG27Pyth>. It's refreshing. In my games against Jester, and with similar moves, I often console myself that one year ago I was incapable such interesting blunders.
My, how we have grown ;>)
Good luck with your game.

|Oct-15-08|| ||brainzugzwang: <Surprised there hasn't been more comment on what a horrific blunder Schallop made with 29.Qd1?? 29.Qb1 is kind of an ugly defensive move, but how does Black proceed from there?>|
Looking closer at my earlier question (now that I'm not at work!), after 29.Qb1 Re2 30.Qg1, White seems to have the key squares covered and is threatening 31.Nxf3, removing one of the key elements of Black's attack. Black can cover this with 30...Re3, but then what? Maybe 31.c5 to end the bishop threats on that diagonal, and maybe free White's bishop with d5 soon? Is there a better sequence for Black than what I gave?
|Oct-24-08|| ||patzer2: For the Tuesday Oct 14, 2008 puzzle, 29...Qg2+! initiates a decoy to win a Rook and then to win the Queen with a discovered attack with check.|
