| May-14-06 | | dakgootje: <Tariqov> i only partly agree, as most people with an alternative solution wants to know as quick as possible whether theirs is right too, thus if such a situation arises it often happens people immediately throw the position in their fritz shredder or other program to analyse, after which they post it. So i think because of that it wont be possible to discuss here completely without computers (dont say we cant try it, only that it probably wont work). on slightly differant subject, i think that there is a possibilty to exclude computers from life games, as there, there is time enough to make some decent analysis before posting and before they moved again... |

 | | Open Defence: <chessgames.com> on some other websites they have an option to post the solution within <hint> </hint> tags that results in the solution being hidden ...so a computer analysis could be hidden that way and only those that want to check it out can see it .. for example I could post "21.Rf8+ loses to <hint> the solution </hint> but i foud that using Fritz or Rybka etc" .. but then again I personally dont use computers.... |
|
| May-14-06 | | dakgootje: <Open Defence> Might be good idea, just like some of the earlier posted ones to do something about the "first"-posters |

 | | Moondoll: I kept looking at 21.Rg7+ Kxg7 22.Qxe3 Nxe3 23.Ne6 forking the king and queen. couldn't figure out what to do if black played Kh8, and I just couldn't see any other clear plan. Interesting puzzle. Good one for Sunday. |
|
| May-14-06 | | EmperorAtahualpa: <Open Defence> Actually this <hint> </hint> system could also be used during live chess broadcasts. There are quite a lot of people who are getting tired of others ruining the conversation with computer engine analyses. See User: adrianp for more details. |
|
| May-14-06 | | EmperorAtahualpa: Completely missed this puzzle again. :( Not much success for me the last few days...I'll be looking forward to Monday! |
|
| May-14-06 | | TheSlid: My joy at getting my first ever Sunday puzzle was short lived. I found <Maria Nikolova>'s line too. Should have looked harder. |
|
| May-14-06 | | percyblakeney: As with live games I personally like to know how computers evaluate the positions, since they understand these things much better than I do... |
|
| May-14-06 | | hdgcfcf: At move 21, I came up with
21. Qxe3 Nxe3
22. Rfd Rxfd
23. Rxf8 Kxf8
24. Ne6
Is there a problem with the move? |
|
| May-14-06 | | RandomVisitor: <hd>I nothing wrong with your sequence... but White just has a better move in 21.Nf3. |
|
| May-14-06 | | jahhaj: <hdqcfcf> (Without a computer) I would say that after 21.Qxe3 Nxe3 22.Rf8+ Rxf8 23.Rxf8+ Kxf8 24.Ne6+ Kg8 25.Nxg5 26.Nc2 White has a poor endgame to defend, he's certainly not winning and could be losing. |
|
| May-14-06 | | numbersguy70: Can someone tell me why Black gives up the knight with Qh6 when Qh5 is available? Thanks |
|
| May-14-06 | | likestofork: <RandomVisitor> I thunk the same thought as far as the 21....Rxf3 line is concerned. It puts up more of a fight than what black did, but it's still pretty hopeless. The R-N combination won't be able to communicate well enough to prevent the Q from picking off the pawns. Sort of like Catherine the Great discarding lovers.....or would that be Vamperella dispatching lovers? Whatever. Black's pawns can't be defended. |
|
| May-14-06 | | c o r e: I saw <hdgcfcf>'s line with 21.♕xe3 but it looked like a draw. I felt certain that there must have been something greater planned, but I couldn't see it. On the subject of computer assistance: it is a wonderful tool. I don't let computers play OTB for me, but they're great for post game analysis and theory preparation. With a little bit of computer knowhow, we can all review our games with a GM- and how could that be bad? |
|
| May-14-06 | | kevin86: Nice ending-I didn't see it coming! :(
I saw a similar game a few days ago. |

 | | OBIT: On the subject of computer-assisted analysis: I think it is okay to have it here, since, as others have said, it does allow us to get to the truth of a position more quickly. For example, in this position I was thinking 21...Rxf3 refuted 21. Nf3 when I initially looked at the solution, since 22. Qb2, 22. Qc3, and 22. gxf3 all seemed to give Black a good game. However, RandomVisitor's 2900 strength computer found the only move here, that being 22. Rf8+! Since the guys using computers seem to be up front about their computer usage, i.e. not claiming they found the moves on their own, they get no complaints from me - let them use that program to find the holes in any analysis cooked up by our feeble human brains. |

| | Open Defence: my opinion is that it is great to have computer analysis but a compromise by giving an option to hide the analysis by a link or different coloured text would serve the wishes of those who wouldnt like to have their individual efforts spoiled while also serving the wishes of those who like to see the evals |
|
| May-14-06 | | old coot: Last! |
|
| May-14-06 | | RandomVisitor: Is there any hope for Black after 21.Nf3 Rxf3?
21... Rxf3
22. Rf8+ Kg7 (22... Rxf8 23. Rxf8+ Rxf8 24. Qxg5 Nf6 25. Qa5 d5 26. Qxa7 Rf7 27. a4 dxc4 28. dxc4 Rd7 29. a5 Kg7 30. h3 Rd1+ 31. Kh2  4.48/24) 23. R4f7+ Rxf7
24. Rxf7+ Kxf7
25. Qxg5 Nf6 (25... Ne5 26. c5 Re8 27. Qf4+ Ke6 28. cxd6 a6 29. h3 h5 30. Qg5 Kxd6 31. d4 3.19/24) 26. Qa5 b6
27. Qa6 Nd7
28. Qb7 Rd8
29. Qxc6 Nf6
30. d4 Rd7
31. Qa4 2.75/21 |
|
| May-14-06 | | alcappacino: What's wrong with 21.Rf8+ Rxf8 22.Rxf8+ Kxf8 23.Ne6+ Rxe6 24.Qxg5 earning the black queen. Now it's White queen against black rook and knight and white should have good chances of winning.
Anything I might have missed? |
|
| May-14-06 | | RandomVisitor: 24...Re1 mate. |
|
| May-14-06 | | isgettingbester: got one! |
|
| May-14-06 | | kolio: I must be blind... What's wrong with simply 21. Rxg4 ? |
|
| May-14-06 | | alcappacino: Thanks RandomVisitor. I certainly did miss something! |
|
| May-15-06 | | RandomVisitor: <kolio>21.Rxg4 Qxg4 22.Qxe3 Kxf7 |
