Both moves win, but it is better to have a full R than an exchange... |

| Mar-29-08 | | Marmot PFL: After the very bad Kh2?? white's position is so bad that black can win with either rook sacrifice, Rxg2+ or Rxf2. The first is more forcing since it rules out delaying the inevitable by Rc8+, but if white plays Bxf2 instead than Rxg2+ Kxg2 e3+ ends it fast. |
|
| Mar-29-08 | | Samagonka: I spent minutes in awe, just marvelling at those rook sacs. Simple, but strong, authentic moves. Just the way chess should be. Unfortunately miles ahead of me. |
|
| Mar-29-08 | | Samagonka: By the way, where's Dzechiel? I would really be interested to read his analysis today. |

| Mar-29-08 | | RandomVisitor: After 25...Rg6 white can keep a small advantage:

| Mar-29-08 | | znprdx: <RandomVisitor: 27...Rxf2 ...also wins> which is what I thought, not seeing what all the fuss was about. But it is kinda like a pistol shot compared to a grenade – although 30.Qf3 is pretty and the kind of move that is the spoiler, the text leaves nothing to chance; like (Shumov-Von Kolisch) the execution is absolute. |
|
| Mar-29-08 | | jovack: Solved this one really quickly surprisingly.
Noticing the white's weak control of the long light diagonal was key. |

|
| Mar-29-08 | | thegoldenband: I got 27...Rxg2+, and saw as far as 29...e3+, though I didn't see for sure how mate would follow. It doesn't look to me as if anyone has pointed out the cutest line -- 29 Bxf2 e3+ 30. Rd5 Qxf2+ 31. Kh1 Qxe1+ 32. Kh2 (or Kg2) Bxd5 and if 33. Qxd5 Qd2+! and Black queens. |
|
| Mar-29-08 | | SuperPatzer77: <cbotev>, You're absolutely right. 29. Bxf2 e3+, 30. Rd5 Qxf2+, 31. Kh1 Qxe1+, 32. Kg2 Qf2+, 33. Kh1 e2! (Note that the White Rook is pinned by the Black Bishop on b7). The Black e-pawn is unstoppable. Like I said, the Black e-pawn is a real killer. After 29...e3+, 30. Qd5 (White hopes for the rank mates) Qxf2+, 31. Kh1 Qxe1+, 32. Kh2 Qf2+ 33. Kh1 Bxd5+, 34. Rxd5 Qf3+ (Black kills two birds with one stone by stopping the rank mate and winning the White Rook). |

| Mar-29-08 | | Creg: 1...Rf3 jumps out at me, though I seem to recognize this position from somewhere. I wonder if I saw it in a puzzle book at one time or another. The threat is 2...Rxg2+ The idea is to break open the wall of pawns around the white king and have at him, say for example. 2.gxf3 Rh6 with the idea of 3...Qxh3 mate should be immediate or shortly there after. Other moves are: 2.g3 Rfxg3 and black breaks in again after 3.fxg3 Qxg3+
2.Rg1 Rxg2+ 3.Rxg2 Rxh3+ and mate next move
This looks good enough for me to warrent 1...Rf3 |
|
| Mar-29-08 | | Creg: SLAP!! That's a smack across the face. Not even close. I totally dismissed 1...Rxg2+ That probably means my original analysis is flawed somewhere, along with my memory of ever seeing this position :) |
|
| Mar-29-08 | | Creg: Oh, duh!! I now see that my plan of Rh6 is met by Bxh6. That does it! I'm switching back to regular and getting away from ever drinking decaf. |

| Mar-29-08 | | idriveacapri: I don't usually get any puzzles after thursday, so I thought this was too easy for a saturday. All the moves are forced. |
|
| Mar-29-08 | | dzechiel: Black to move. Material even. "Very Difficult."
This looks like a double rook sacrifice to me. How about 27...Rxg2+ 28 Kxg2 Rxf2+ 29 Bxf2 e3+ 30 Rd5 Qxf2+ 31 Kh1 Qxe8+ 32 Kh2 Qf2+ 33 Kh1 Qf3+ 34 Kg1 Bxd5 and black is up a rook with lots of pull.
I wish I was able to work on this last night, but only now have I had a chance to look at this position. I predict lots of people saying this was the easiest Saturday ever. Time to check. |
|
| Mar-29-08 | | zooter: Missed it, i thought Rxf2 wins |
|
| Mar-30-08 | | Azo: What about 27 Re2? |
|
| Mar-30-08 | | dabearsrock1010: this was a pretty easy saturday puzzle but really pleasing |
|
| Mar-30-08 | | patzer2: For the Saturday, March 29, 2008 puzzle solution, the demolition sacrifice 27...Rxg2+!! does the trick. |
|

 | | kevin86: Black rolls down the rooks to sacrifice,then rakes in the cash... |
|
| Jan-04-11 | | 4tmac: GM Schmid is better suited for correspondence (as you would expect from a famous arbiter). He needed to play 27. Qc2 but did not appreciate the weakness at f2. After Kh2? it was Mate in 13 starting with a devastating double rook sacrifice. |

| Apr-19-12 | | LoveThatJoker: Guess-the-Move Final Score:
Schmid vs Rossolimo, 1949.
YOU ARE PLAYING THE ROLE OF ROSSOLIMO.
Your score: 48 (par = 31)
