 | | Patriot: Hi <morf>! Thanks! But what you saw today was a "finished product". I spent a good 20 minutes or more on this problem and just didn't feel very methodical. It seemed to go in circles, not maintaining focus long enough to accept or rule out candidates. As I said in the past, when you don't know which candidate is best then pick one and stick with it until it becomes clear. And don't try to prove a combination works--try to refute each move along the way. Win, lose, or draw, go back and look at what other options may have existed and see if the evaluation is still correct. If white wins, go to black's previous move and see if there was something else black may have had. If not, go back again to a previous move for black and again see if there was another option. I've come to realize that this is basic mechanics of chess calculation, and it has the potential to have a lot of permutations. Usually though, we have to guess because of time constraints--hopefully our evaluation ability is good enough to do this in many cases. 45.Rd8 didn't even occur to me, although it threatens an immediate mate. So it may be that I "lucked out" and saw the right move first (45.Rd7). But I also remember trying to threaten Bd5+, winning the queen on a7 so there is really a double-threat in Rd7 and usually double-threats prevail because it is hard to stop 2 threats at once. By the way, Dan is sending me his latest book "The World's Most Instructive Game Book". Like the last one, it probably contains my name for helping out. |

| | Patriot: <morf> Good job on the Saturday problem! I missed so many things in my post, including the queen hanging (many times). For one thing, I didn't get a good night's rest and the position had so many captures--and within those, multiple captures. Plus I didn't feel there was anything right off that could potentially be winning for white--a sense of moving in the right direction. So pretty much everything had to be considered. But it helps when you notice ALL current threats! |

| | Patriot: Hi <morf>! Good job on the Sunday problem! I especially like the mate you found at the end, starting with 30...Qd3+.
We both missed the 29.Nd4 idea although I'm not so sure it is critical to find. In hind-sight we know the answer, but it's not like black is losing anything there since white's rook is also hanging. And of course, that logic can also be dangerous in other positions where a knight move like that can cause serious problems. Essentially each attacking move has to be examined to truly know sometimes. Overall, I feel pretty good about solving it, but...I didn't feel good about what it took to get there. In order to actually play like this, my approach would have to be a lot cleaner--there is just too much fumbling around to make it practical. There seems to be a dizzying array of possibilities I have to go through before drawing conclusions. And I have to remind myself that I'm trying to refute my own moves--not find a certain combination that wins. However since this is a forum, I feel compelled at times to draw attention to what I know is a bad line and why it loses. And that's not my goal--I'm not trying to write a book, but instead use this site to help develop calculation ability to be used OTB if possible. |

| | sevenseaman: Good morning <morf>. Nice sol #20147. Excellent powers of recall! First time for me but I thoroughly enjoyed it from the old master. In case you or others need them I have posted sol to some other nasty ones on my page. |

| | sevenseaman: Hi<morf>, see this one. #43769 Sometimes we spot it straightaway and at other times not at all. This is one of the latter cases where most of the good solvers failed to see the first key move. Yet it is utterly logical and so simple that one later bangs one's forehead in despair, 'how could I have missed that!'

| | Patriot: Thanks, <morf>! Actually I didn't see that 40.Qh6+ is winning but thought 40.Nxc7 looked clearly better short-term so I didn't pursue the other line. |

 | | chesstoplay: Hi < morf >,
TY for the kind words.
Yeah, Var is one of the good guys.
We have such a strong team this game and many strong personalities as well. I agree that it is important to be fair and decent to players like GMVA who give us their time and a good game. Plus he tells pretty good jokes!

| | sevenseaman: Thanks <morf>. You have sent me the Caissa FEN link twice. I have not had the time or the occasion to use it and so have not been able post my appreciation/view on it. Will do it the soonest. http://www.caissa.com/chess-tools/p... |

Do I feed it the position before the move <30. f5> with an FEN or what? Will you work the details as an illustrative example on my page please. |

Dec-15-12
| | sevenseaman: Hi <morf>, good morning. #56796 <1. Kh3> is well found, good. The next White move after Black plays <1...gxh6> is trickier and so I wont let you go with just the first. Here is #100030, almost as crisp as #56796, and involves similar smart thinking.

BLACK ANNOUNCES MATE IN 11 AFTER DAZZLING QUEEN SACRIFICE! 33.Nf5 Qe7 34.Nxe7+ Raxe7 35.Bxh6 gxh6 36.Rxh6 Rg7 37.Rxc6 Rxg4 38.Rch6 Reg7 39.Rf2 Re4 40.Rxh7 Rxh7+ 41.Kg2 Rg7+ 42.Kf1 Bh4 43.Rg2 Re1# 
click for larger viewFormer WT spokesperson, Zig Zwang, who was immediately fired after the catastrophe, was asked how this could possibly happen. Zig replied "I take full responsibility. Only now is the folly of <38.Rxh6> clearly obvious. Blinded by an attack down the h-file, I ignored my teammates pleas for <38.Rc8>, which wins on the spot, and lobbied for this losing Howler, which the voting public fell for. Canadian Chess reporter Dan Lang Sackitall, wasn't buying any of it. Sackitall asked, with some heat, "Sorry Zig, thats not good enough. The International Chess community deserves better. I mean, Jupiter Bloopiter, White's position was so strong, the Queen sac could've been ignored and they still would've won. What on earth happened?" Zig, clearly overcome by the tragic loss and his subsequent dismissal, could only croak out a few halting words "I'm sorry, this has all been too much..." And he turned away, walking slowly, lost in his own thoughts; thoughts that probably dealt with having to live with his name forever attached to a game labeled: 'Zig Feld Follies'
