 | | agb2002: I would like to know how it is possible to see the maneuver Re7-Re1-Qf4 and fail to see the rather obvious Qc1+. Better luck tomorrow. |

 | | Willber G: Well I went for 35.Rc6 with a view to creating pressure and exchanges with (eg) 36.Rc8, or if 35...Rd8 then 36.Qb7. But I didn't look very deeply. |

 | | benveniste: I have to add this one to the neverending "I'm a woodpusher" pile. I worked out that it was a spoiler and still chose the wrong move. I found the ♖e7 swindle but not the white knight trap after ♖xd6. So I said to myself: "Self -- you're two pawns up. Play ♖e1, plan to get your queen off the edge of the board and consolidate your gains." |

 | | chessgames.com: Today is your Christmas Eve spoiler.
The variation 35.Rd6?! Rxd6 36.Qb7+ Qxb7 37.Nxd6+ is allluring but throws away White's advantage. Our intended solution is the simple approach of 35.Re5, but there are probably other strong moves as well--we'll leave it up to you to hash those out. |
|
| Dec-24-10 | | Patriot: With white being two pawns up, I just want to play simple chess and make sure black has no counter-play. 35...Kxe6 is threatened and I could find no "tricks". Also, I noticed that on 35.Rc6 perhaps 35...Qf4 is a problem. Therefore I settled on 35.Re5, without being very confident because this is a puzzle and there should be a knock-out somewhere. 35.Re5 seemed like the only practical solution. <<agb2002>: I would like to know how it is possible to see the maneuver Re7-Re1-Qf4 and fail to see the rather obvious Qc1+.> I looked at 35.Rd6 momentarily and didn't see that 35...Rxd6 36.Qb7+! simplifies. So maybe luck had something to do with my answer. To (sort of) answer your question, Dan Heisman has a suggestion for positions like this. He says that whenever you are winning, it's a whole different game. That is, your approach should be different. He says you should "Think defense first!" which, he emphasizes, it doesn't mean to think defensively. It means that when you are winning you have more to lose and therefore their threats become more important than your own. Luck may have something to do with me solving this, but it was also Dan's advice because I did notice that ...Qf4 might become a problem and that Re5 stops that possibility. |

| Dec-24-10 | | 5hrsolver: <dzechiel 36 Qb7+ Qxb7 37 Nxd6+ Ke7 38 Nxb7 Kd7 and it looks like white has managed to trap his knight.> White can reply 39.b4
The white knight can go to c5 and trade itself for the b pawn and end up with three connected passed pawns on the queenside. That and white can create another passer with the h pawn. I looked at some lines and white could actually win this endgame. I would have gone into this endgame but I did not see the black defense 35...Re7. So overall the suggested move 35.Re5 is the best. It gives white time to consolidate his position and make his material advantage count. |

| Dec-24-10 | | VincentL: "Medium/Difficult".
I have looked at this for a few minutes, and cannot see anything "spectacular" for white. After 35. Re5 or perhaps 35. Re1 surely white should win with the extra two pawns. I am blind today and out of time, so must check. |
|
| Dec-24-10 | | VincentL: Well, I didn't fall for the line I didn't see.
Perhaps that´s one point for me. |

 | | Jimfromprovidence: FWIW...when I re-looked at the puzzle this morning, I wondered why black did not play 36...Qf4 instead of the text 36...Re1+, as 36...Qf4 threatens ...Re1#.

| Dec-24-10 | | Patriot: <Jimfromprovidence> <But that loses to 37 Rxf5+ Qxf5 38 Nd6+> Good point!
Merry Christmas, everyone! |

| Dec-24-10 | | Marmot PFL: Time wasted on this one...white is 2 pawns up, better position, so my reaction is to play safe, but not passive. This is a quiz though, so look for something forcing...and look and look. 35 Rd6 Rxd6 36 Qb7+ Qxb7 37 Nxd6+ Ke6 38 Nxb7 is tempting but doesn't Kd7 trap the knight? Too complicated... Finally I say play 35 Re5 and if there is a better move congrats, at least i didn't blunder. |
|
| Dec-24-10 | | estrick: With both Black's queen and rook being "loose" I thought there should be a tactic in there to win something. Looked for a way to draw Black's queen to a square where it could be forked but did not see the possibility of sacrificing the rook on d6 and the queen on b7 in order to get that in. So, I completely missed the "alluring" combination (which Black didn't fall for anyway) and would have played the more prosaic Re5 because a) it's under attack and needs to go somewhere, b) it threatens the pawn on f5 from there, c) it cuts off Black's queen's scope on the b8 - h2 diagonal, d) it seems to be safely posted on e5 with the pawn on d4. |

 | | scormus: <CG ? Better is simply 35.Re5> couldnt they have said a bit more? I thought Re5 was the most logical move, but I had no idea as to how it would continue. Something like 35 ... Kf6 36 Qa4 and 37 Qb3 or Qb2 maybe? B can occupy the h file and the win for W is surely very difficult. Oh well at least I didnt pick Rd6 :-\ |
|
| Dec-24-10 | | Arcaprico: what about 35. Rc6? |
|
| Dec-24-10 | | hedgeh0g: Re5 made sense. No need to simplify to a better ending when you can gain an even bigger advantage in the middlegame. |
|
| Dec-24-10 | | BOSTER: Even before I understood how to do this
I knew that the knight royal fork is here.
This the typical petite combo is very attractive to stop count anything else.
So 35.Rd6 if Rxd6
36.Qb7+ Qxb7
37.Nxd6+ Ke7
38.Nxb7 Kd7
But when you see couple moves ahead you can see that white knight is trapped.
Certainly, black can count this easy,and even after they win the knight they can not hold the position.
39.h4 gxh3 40.gxh3 Kc7 41.Nc5 bxc5 42.dxc5 Kc6 43.b4
So black prefer to sacr.the knight on d5 and take the open"e" file to penetrate into white camp, where they have good chances to draw.
If you understand all this very good maybe the best move in the position on diagram 35.Re5 and return rook and queen in own camp. |

| Dec-24-10 | | gofer: I am in my Mum's kitchen, with orders to butter up the turkey, stick it in the top oven for 25 mins at 24:00 and then stick it in the low oven over night. So if I forget then I have screwed up Christmas lunch! That in mind I was quickly looking at this one with my step-brother-in-law (is there such a thing?) and trying to show him my brilliance before he toddles off to bed... "35 Re5 ..."
I say and lets check...
...bingo!
Ahh... ...but then I read the posts and see I have completely missed the point! There was a spoiler that I never saw and my dull and practical move, should only have been played after finding the spoiler and discarding it... ...oh well... ...roll on Christmas morning... ...oh yes I have one other chore to do this evening. The stockings for my two kids. Now if I forget THAT I will have REALLY ruined Christmas...! |

| Dec-24-10 | | wals: I went for 35.Rd6 expecting the majority of five pawns to three would be sufficient for a White win.
How easy it is to overlook a backward move.

"Feliz Navidad" to those in this continent, for whom we have "Nochebuena" this evening. |

| Dec-24-10 | | Fezzik: Amazing! A "normal" move wins in a puzzle!
I spent a long time on various sacs, including Rd6. I didn't see as much as Georgiev did, but I also didn't see any sac that worked. In a real game, I probably would have played Re5 or even Re1 in that position. |
|
| Dec-24-10 | | patzer2: I quickly settled on today's Friday 35.Re5 solution because I could not find anything better. The Knight Fork combination to "simplify" to a pawn versus Knight ending after 35. Rd6!? Rxd6 36. Qb7+ Qxb7 37. Nxd6+ Ke6 38. Nxb7 Kd7 39. Kf2 Kc7 40. Nc5 bxc5 41. dxc5 Kc6 = leads to a level but difficult end game for both sides. The defensive resource 35...Re7!?, offering two pieces for perpetual check after 35...Re7!? 36. Rxd5 Re1+ 37. kf2 Qf4+! =, is a clever defensive maneuver. |
|
| Dec-24-10 | | TheBish: I concur with Fezzik's remark -- it's unusual for a "normal" move to be the correct one. I didn't see the tactical trick in the game, but that was only good for a draw anyway. I did see that Black's queen could get active in a hurry, and that 35. Re5! kept it in "check", i.e. out of White's "house" (king area). That was a pretty cool attempt at simplification though -- I would be tempted to play it in a game if I saw it (one of many reasons I'm not a GM). |
|
| Dec-24-10 | | tacticalmonster: 1) White is up two pawns
2) his rook is hanging and his queen is out of play
3) Black threatens Qf4 to exploit White's lack of any defensive piece 4) Black's king is exposed and his kingside pawns are far advanced, but Black's active pieces provide sufficient king protection candidate: Re5- this move just stops Qf4 Black has many ways to go from here: f4, Kg6 or Ne7. It's close to Christmas and I don't have time for this |
