|Oct-10-12|| ||elocym: No matter what happens Rf8#|
|Oct-10-12|| ||andrewjsacks: Geometric.|
|Oct-10-12|| ||Phony Benoni: Not a true back rank position, but with the Black king's only escape cut off you immediately start thinking of ways to get Black's pieces off their spots.|
My first thought was 29.Bc5, eyeing a possible mate on f8, but that's not forcing enough; the Black rook on e8 can't be lured away. Then I took a look at <29.Bd4>, and things started to click.
<29...Qxe2 30.Rxg7+ Kh8 31.Rxg6+> is another familiar idea. Black is forced into <31...Qe5>, but after <32.Bxe5+> the unlucky castle is overloaded.
I have to admit I didn't immediately see the nice line 29...Qxd4+ 30.Rxd4 Rxe2 31.Rd8+ and mate next.
|Oct-10-12|| ||Abdel Irada: <Break on through...<<<>>>>|
White is a bishop ahead, but the bishop is pinned, thrice attacked, and our eyes tell us it's going nowhere except into the captured pieces pile next to the board. But our eyes can deceive us sometimes, and when we bring imagination to bear, we can cleanse the doors of perception and "see" fresh possibilities.
Here White violently breaks the pin with the deeply counterintuitive
Black is now faced with what must have been a shocking dilemma, and has two lines of defense:
<(1) 29. ...xd4†
30. xd4, xe2??
31. d8†, e8
So far, so doubleplusungood. But Black does have another and (slightly) better option:
<(2) 29. ...xe2
30. xg7†, h8
31. xg6†, e5
32. xe5†, xe5
Some rules, it has been said, were made to be broken. And as we see here, so were some pins.
And when this happens, the defender can try to run, try to hide, but eventually we can break on through to the other side.
|Oct-10-12|| ||Coigach: 29.Bd4 is a killer, offering the Q for a mating combination ...Qxe2 30.Rxg7+ Kh8 31.Rxg6+ Qe5 (31...Re5 32.Rf8#) 32.Bxe5+ Rxe5 33.Rf8#.|
The Black Q cannot move off the e-file other than by 29...Qb8 or else 30.Qxe8# and if 29...Qb8 30.Rxg7+ Kh8 31.Rxg6+ Re5 32.Bxe5#.
|Oct-10-12|| ||TheBish: D Zagorskis vs J Michenka, 1994|
White to play (29.?) "Medium/Easy"
White is up a piece (for a doubled g-pawn), but Black has piled on the pinned Be3 and appears to be winning the piece back. But White can turn the tables by switching to an attack on the king, taking advantage of the particular placement of Black's pieces with a combination of attacks.
29. Bd4!! Qxe2
Whether White's move warrants two exclams is debatable, but I'm giving it a second one for it's shock value; Black probably didn't see it coming, and assumed he was winning the piece back. If 29...Qxd4+ 30. Rxd4 Rxe2 31. Rd8+ and White mates. Black's queen is actually overloaded here, not able to guard both the Re8 and pawn on g7, with the back rank so weak.
30. Rxg7+ Kh8 31. Rxg6+ Qe5
Or 31...Re5 32. Rf8#, but resignation is more likely here.
32. Bxe5+ Rxe5 33. Rf8#.
|Oct-10-12|| ||dzechiel: White to move (29?). White has a bishop for a pawn. "Medium/Easy."|
It sure looks like white is going to have to give the piece back, so why not up the ante and make it a queen?
29 Bd4 Qxe2 30 Rxg7+ Kh8
I found all of this pretty quickly, but at this point I kept looking for a way to play the rook along the 7th rank (eg 31 Re7+), but that wasn't working.
Then I looked at moves like 31 Rff7, but that failed to 31...Qe1+ 32 Kh2 Qg3+.
Finally I looked again at the rook on g7, and this time the move
jumped right out at me. Black is running low on moves now, having just
- 31...Re5, and
Both lose quickly:
31...Re5 32 Rf8#
31...Qe5 32 Bxe5+ Rxe5 33 Rf8#
A pretty mating combination.
|Oct-10-12|| ||sarayu: i got this almost immediately playing it out, but couldn't have kept it in my head otb. Beautiful combination.|
|Oct-10-12|| ||bachbeet: Got it. Very interesting Q sac that really led to no real gain for black. Great use of the rook tandem with that pesky bishop.|
|Oct-10-12|| ||Patriot: 29.Bd4
29...Qxe2 30.Rxg7+ Kh8 31.Rxg6+ Re5 (31...Qe5 32.Bxe5+ Rxe5 33.Rf8#) 32.Rf8#
29...Qxd4+ 30.Rxd4 Rxe2 31.Rd8+ Re8 32.Rxe8#
|Oct-10-12|| ||M.Hassan: "Medium/Easy"
White to play 29.?
White has a Bishop for a pawn.
Bishop occupying the long diagonal brings win for the White, no matter what:
|Oct-10-12|| ||M.Hassan: correction:
30.Rxg7+ Not Rxg2
|Oct-10-12|| ||jheiner: Didn't get this via visualization. I saw 29.Bd4 quickly but thought it was a spoiler from CG with Black able to even up 2R vs. 2R. If I had moved the pieces on the board, no problem, but missed the Rxg6 finisher.|
Good puzzle. Elegant attack. I particularly like the pattern the White holds control over the f file which creates a back rank threat, but then shortly after nips off the Pg6 and now creates the same situation but by squeezing control of the g-file instead.
|Oct-10-12|| ||Once: A prediction ... today someone will say "I only got it because it's a puzzle and I knew there there had to be a combination. I wouldn't have seen it OTB."|
It is true that the CG environment is artificial. In a real game, no-one points out that a fancy tactical blow is available. Well, not within the rules anyway.
How can we spot more of these tactics in the real world? How can we transfer our "got it"s from CG to OTB? Can we have a little helper who tugs on our sleeve when a tactic is possible?
One concept that might help is the idea of a <half-mate>. A half-mate is when one of the two kings is close to mate. He is short of moves, perhaps even stalemated. There is a heap of firepower shining down on him.
When we see a half-mate on the board, whether it's our king or the enemy's, we need to be extra vigilant. This is a time when tactics <may> be possible. After all, if we can complete the mate pattern it doesn't matter how much wood we throw to get to that point.
Take today's POTD. White has two powerful rooks in the vicinity of the black king who only has one flight square - h1. We can dream of deflecting th e8 rook and playing Rd8 mate. Or we might be able to get in Rff7 followed by Rxg7+.
We lick our lips, rub our hands in anticipation. We're into half-mate territory. It's no guarantee that a tactic will be possible, but it's a sure-fire indication that we ought to be looking for one. The position is gnarly, crispy, ripe. If there was a musical soundtrack, it would be playing fast-paced dramatic music. Something is about to happen ...
And that's when we look at moves like 29. Rff7 (which doesn't work) and 29. Bd4 (which does). In each case, we are bringing another piece into the attack, even if it means dropping our queen.
Is it just me, or are the positions easier this week than in recent weeks?
|Oct-10-12|| ||newzild: Damn. Thought it was Black to play ... No point for me!|
|Oct-10-12|| ||scormus: Nice elegant forcing line after 29 Bd4 Qxe2, I see no other obvious feasible reply for B.|
<Once> I won't say I definitely wouldn't get this playing OTB, but I might well miss it. One of the attributes of the Master player is a kind of 6th sense about when a tactical strike will secure an advantage - I guess its the overall familiarity with patterns and positions. And the stronger the player the more developed that is and the more possibilities they will see.
Yes, although the puzzle situation is artificial, it does help to develop this attribute (at least so I tell myself)
|Oct-10-12|| ||Djoker: 29. Bd4
A. ...Qxe2 30.Rxg7+ Kh8 31.Rxg6+ Qe5 32. Bxe5+ Rxe5 33.Rf8#
B. ...Qxd4+ 30. Rxd4 Rxe2 31.Rd8+ Re8 32.Rxe8#
In B. there is no good move after 30.Rxd4 30...Rf8 is answered by Rxf8 and Rf4+. I think Rcc8 might be best move but even that leaves Black with a pretty bad position.
|Oct-10-12|| ||gofer: A simple cross pin.
<29 Bd4! ...>
29 ... Qxd4+
30 Rxd4 Rxe2
31 Rd8+ Re8
<29 ... Qxe2>
<30 Rxg7+ Kh8>
<31 Rxg6+ Qe5>
<32 Bxe5+ Rxe5>
|Oct-10-12|| ||gprice: A pretty variation is
29 ... Qxe2
30 Rxg7+ Kh8
31 Rxg6+ Qe5
32 Rf8+ Rxf8
33 Bxd4+ Rf6

Complete domination! (not the quickest
way to win of course but black drops everything)
|Oct-10-12|| ||captainandrewwiggins: ok, white's a piece up so things are looking good. I want to keep my bishop on the board, it's beautiful. but i noticed: (i) i can fork the queen and the rook with the bishop, the nicely placed white rook on the 7th rank is a massive headache for black. the only problem is that the bishop is pinned to the queen. no matter, there are nasty discovered threats and mates on g7 and g8 once the black queen sac's the white queen on g2.|
originally i thought through the line 29. Rf7! i wanted to get either my queen or rook on the 7th rank for an assault on the white king, but then black could sac my bishop with qxe3+ and white looses the initiative. sure white would be able to eliminate a lot of the black pawns on the 7th rank and this should be winning, but why trouble oneself with that.
in short, 29. bd4!! is devastating. if black decides to sac my queen then a simple 30. rg7+, Kh8 is followed with 31. rh7+, Kg8 followed by mate 32. rh8#
time to check.
|Oct-10-12|| ||captainandrewwiggins: oops i just dropped my rook :(|
|Oct-10-12|| ||whiteshark: <29.Bd4!!>, and that's it. |
(It was fun to work all variations out)
|Oct-10-12|| ||Abdel Irada: <jheiner>: <I saw 29.Bd4 quickly but thought it was a spoiler from CG with Black able to even up 2R vs. 2R. If I had moved the pieces on the board, no problem, but missed the Rxg6 finisher.>|
Before I looked at 31. xg6, I briefly thought I'd be facing an endgame after 29. d4, xe2; 30. xg7†, h8; 31. e7†, g8; 32. xe2, xe2; however, after 33. xc3, xa2; 34. f2, White is still winning. Black has temporary counterplay with his advanced a-pawn, but the bishop and king will soon corral the queenside pawns, and White will go on to win with his own b-pawn.
|Oct-10-12|| ||LoveThatJoker: <29. Bd4! Qxe2>
(29...Qxd4+ 30. Rxd4 wins as 30...Rxe2 31. Rd8+ Re8 32. Rxe8#)
<30. Rxg7+ Kh8 31. Rxg6+! Qe5>
(31...Re5 32. Rd8#)
<32. Bxe5+ Rxe5 33. Rd8+ Re8 34. Rxe8#>
|Oct-10-12|| ||LoveThatJoker: PS. I got the answer correct today, but for some reason kept thinking that the R administering mate was the one that in the puzzle diagram started on d7.|
Of course, the R that delivers the coup de grace is the R on f1.
This is an oversight, but thankfully not a serious one that might lose me points for today, as it is obvious that the only R that can deliver mate is the idle one and not the one on g6! ;)
