|Jul-14-12|| ||The Last Straw: Missed 31.Rd8. I got 28.Bxg6 hxg6 29.Re7+ Rxe7 30.dxe7 Kxe7 31.h7 and then started thinking about how to drive the a8-rook away.|
|Jul-14-12|| ||Seaholme: Just got hom from the swedish championship, saw the winning variation instantly. I guess a week of chess really makes you more alert.|
|Jul-14-12|| ||Winner12: Rd8 !!|
|Jul-14-12|| ||bachbeet: I thought of the first few moves but really didn't see the advantage because I didn't think about moving that rook to d8. That is definitely the key because it puts two black pieces in the way of taking the potential promoted Q on h8. I'll give myself only a couple points for this one.|
|Jul-14-12|| ||LIFE Master AJ: I think I saw this in one of my tactics books or in a magazine somewhere ... |
28.BxP/g6!!, hxg6; 29.Re7+!, RxR/e7; 30.dxe7+, Kxe7; 31.Rd6!, and the Pawn will promote.
|Jul-14-12|| ||LIFE Master AJ: << Jul-14-12 <Jimfromprovidence>: I liked 28 cxb5 Bb7 29 Rdd1. |

The idea is 30 Ba4, seeing b6+. <<>> >>
I think that this wins, did you check it with an engine?
|Jul-14-12|| ||James D Flynn: Candidates Bxg6, Rd1, cxb5.
28.Bxg6(the most trenchant) hxg6 29.Re7+ Rxe7 30.dxe7 Kxe7 (else Rd8 which can transpose with a tempo gained) 31.Rd8 Kxd8(Black cannot stop the h pawn from queening so he picks up the most material he can) 32.h7 Bb7 33.a8=Q+ Kc7 34.Qg7+ Kb6(Kc8 35.Qxg6 simply loses a tempo) 35.Qxg6+ Ka7 36.Qd6 Rg8+37.Kf1 f3 37.Qxc5+ Ka8 38.Qa3+ Kb8 39.Qd6+ Ka7 White can keep checking on a3 and f8 but does he have a win?
28.Rd1 Bb7 29,Rxc5 Rc8 30.Rxc8 Bxc8(if Kxc8 31.d7+ Rxd7 (or Kd8 32.cxb5 followed by Ba4 and Re1 Black must then sacrifice the R for B and P with a hopeless endgame)32.Rxd7 Kxd7 33.Bxg6 and the h pawn will queen winning)31.cxb5 and the c pawn will advance winning.
29.cxb5 (The safest) Bb7 30.Bb3 Bxd5 31.Bxd5 Raf8 32.Bc6+ Kd8 33.d7 f3 34.Kf2 and White’s a and b will advance winning.
The tactical Bxg6 wims Q for R and B but the strong f pawn appears to hold the draw for Black. Both cxb5 and Rd1 appear to win. Now for the game.
|Jul-14-12|| ||PeaceRequiresAnarchy: I'm very proud to say that I found this in about two minutes.|
Literally just before this puzzle I did a Tactics Trainer problem on Chess.com that involved promoting a pawn on the 7th rank:
It took me 2 minutes and 51 seconds to do that Tactics Trainer problem. The average time was only 1 minute and 29 seconds, so I did not do very well. As I said on the comment page of the problem, however, it took me a very long time to spot that I even had a pawn on the back rank that I could possibly promote. As soon as I spotted this possiblity (about 2 minutes and 45 seconds into the problem) it took me literally about 5 seconds to finish the puzzle successfully.
Coincidentally today's Puzzle of the Day here on ChessGames.com involved a pawn promotion as well.
Just now when I spotted the pawn on the 7th rank I immediately thought, "How can I promote this pawn?" I spotted the bishop sacrifice and the Re7+ move to get rid of black's rook. Then with a little calculation I found that Rd8! was necessary to prevent black's other rook from being able to defend h8 in time. I found the correct move order and was confident that I had the solution. And sure enough I did!
It's awesome that I solved this puzzle faster than the Tactics Trainer problem on Chess.com. I don't usually even solve Saturday or Sunday problems unless I stare at them for 20 minutes, and even then I often only get the basic idea without managing to calculate every line perfectly.
Hope someone enjoyed my story :-). I found it exciting.
|Jul-14-12|| ||jancotianno: Quite an easy one for a saturday puzzle but a brilliant one nonetheless.|
|Jul-14-12|| ||rahulthemoron: i understand the chess, i don't understand chrisowen - is he using some sort of special slang?|
|Jul-14-12|| ||perfidious: <rahul> Where Ah come from, they call it word salad.|
|Jul-14-12|| ||Patriot: <PeaceRequiresAnarchy> Good job! :-)|
|Jul-14-12|| ||PeaceRequiresAnarchy: <Patriot> Thanks :-)|
|Jul-14-12|| ||gawain: I had the right idea but I did not see that 31 Rd8 was necessary. I thought the h-pawn was unstoppable after 30 dxe7+ just because the K could not catch it. So I was wondering what was so "difficult" about this one! |
The laugh is on me. I did not consider the Black a8 rook which would be trained upon the h8 square after the bishop moves. So sacrificing the rook on d8 is the only way. It was very difficult after all.
|Jul-14-12|| ||I play the Fred: I cheated on this one; I remembered this (or maybe it was a similar position) from Soltis' <The Inner Game of Chess>, and thus remembered the finish beginning with Bxg6. That <31 Rd8> sure does leave an impression.|
|Jul-14-12|| ||JimmyRockHound: Rd8 very sweet. Gives white time to queen the pawn.|
|Jul-15-12|| ||perfidious: < I play the Fred: ....That <31 Rd8> sure does leave an impression. >|
Indeed it does-at first glance, it's nonsensical but is the logical followup to what went before.
|Jul-15-12|| ||I play the Fred: <perfidious>, ya old sea dog! How the hell are you?|
To get you up to speed, shortly after your sabbatical began, <AJ> and I had a ferocious flame war on top of Mount Rushmore. He came straight for my throat, but thanks to a discarded banana (I had already eaten the peel) I slipped beneath his attack and the <Pensacola Python> flew over me and painfully caromed down Abraham Lincoln's nose. Since I didn't see a corpse in the aftermath, I have to assume he'll be back for the sequel, perhaps returning as half-man, half-chess engine called <Darth Fyde>.
In his absence I have assumed the title of <LIFE Master>. You know, because there can be only one.
|Jul-15-12|| ||I play the Fred: On to less important matters: I went and checked the Soltis book. I had assumed my memory was a bit hazy (on the game details, not the concluding moves), but it turned out that Soltis had identified White as <Boey> and given 1972 as the year. Bit the real kicker was this:|
<Why [28. Bxg6]?...even though it <is> a sacrifice, it is the <least> forcing move in the series...black could have ignored 28. Bxg6 (28...Rf6 29. Bxh7 Rxh6; 29. Bf5+ Kd8). At least his position would not be a forced loss.>
GM Andrew Soltis, p. 175, <The Inner Game of Chess>. The question is, is he right? I took a quick look at 28 Bxg6 Rf6 29 Re7+ Kd8 30 Bxh7 Rxh6 31 Rg5 Bd7 32 Rgg7. This seems to do the trick, but I have yet to find a good answer for 29...Kc6.
|Jul-15-12|| ||Abdel Irada: <rahul>:
I gave up trying to understand Chris Owen. His messages are obviously encrypted, and obviously he has forgotten to supply us with the key.
I'll start reading him again when the second coming of Alan Turing arrives and cracks his code.
|Jul-15-12|| ||perfidious: <Fred> On Mt Rushmore? Really? It's lonesome out in the Badlands!|
The <Pensacola Python>, is it? That's quaint. Come to that, I decided it was best to nail that iggy switch for him-much quieter that way.
You mentioned Josef Martin Boey, then a top Belgian player. It seemed odd that he should play 1.d4, because my recollection of him was as a lover of 1.e4 for White and various less commonly played lines such as the Schliemann every chance he got when defending the Spanish Torture. Turns out there are a few-very few-games of Boey's as White with queenside openings in this DB.
|Jul-15-12|| ||perfidious: <Abdel Irada: <rahul>: ...I'll start reading (<chrisowen>) again when the second coming of Alan Turing arrives and cracks his code.>|
Do you think even Turing's brilliance would be enough to overcome that flood of word salad?

Ugh. Obviously, 32 Rg8+ Be8 33 Rgxe8# is better than 32 Rgg7. But on to 29...Kc6 30 Rc7+ Kb6, then.
The best I can do with that is 31 Bxh7 Bb7 32 Rdxc5, but I don't see a forced win in sight. Sure looks difficult for black, though.
|Jul-15-12|| ||I play the Fred: 29...Kc6 30 Be8+ Kb6 31 d7 seems to do it. Apparently, 28 Bxg6 is a forced win even if black refuses the bishop.|
