| Dec-23-05 | | simsan: THATS SOO COOL! I was thinking Ra7!
Initially I was extremely disappointed that my move was wrong, but since I couldn't see the weakness myself I ran the position through chessbase light :-)  (3.78) 36.Ra7 Qc8 [ .. gxf5 37. exf5 Kh8]37.Re7 gxf5 38. Rxe6 Kh8 (2.66) 36.Ne7+ Bxe7 37.Qxe6+ Kf8 38.f4 exf4
I guess I didn't see all the possible continuations after Ra7, and neither did I see the Ne7+ alternative... so I guess didn't completely solve it today either... |
|
| Dec-23-05 | | simsan: What a nice early X-mas present: being in contention for the friday puzzle.. |
|
| Dec-23-05 | | aginis: <tariqov> im pretty sure its 36.Re7
then 36...Bxe7 37.Qxe6+ Kf8 38.Nh6 Kg7 39.Nf5+! <39.Ke2 Qf8! 40.Qd7 Qd8! 41.Qe6 Bxg5! <<Not Nxg5 Bxg5! Bxg5 Nf7! Qf6 Nxg5 Qxg5 Qxd6 >>42.Nf7! Qf6!! 43.Nxg5 Nxg5 44.Qxf6+ Kxf6  > 39...gf! 40.ef Qf7!! 41.f6+ Nxf6 42.gf Qxf6  |
|
| Dec-23-05 | | dakgootje: <EmperorAtahualpa> ty for that analysis =) As several others i went for 36. ♖e7 ♗xe7 37. ♕xe6+ ♔f8 38.♘h6. I did see of course the possibility of 36. ♘e7 but i didnt see 37. ♘e6 after 36. ♘e7 ♔f7 and thus abandoned that line... |
|
| Dec-23-05 | | Tariqov: <aginis> oops i'm getting blinder it's 36Re7 not 35Re7.After 39Nf5gf(!,?or?!)40efQf7! (your 41f6?? is a blunder that simply gives Black the upperhand)what if 41Qxf7+Kxf7 42g6+ not sooo sure if white is winning but definitely think that that B is not winning.Besides there lot of other move such as 39Nf5+gf 40Qh6+(which might work):) |
|
| Dec-23-05 | | aginis: why not 36.Ra7 Kh8 37.Ra8 Qxa4 38.Qxe6 Qd1+ looks a lot like perpetual check to me. |
|
| Dec-23-05 | | aginis: <tariqov> 36.Re7 36...Bxe7 37.Qxe6+ Kf8 38.Nh6 Kg7 39.Nf5+! gf 40.ef Qf7 A.41.f6 we discussed above and i agree its probably not the best option B.41.Qxf7??(white doesn't want to simplfy the position by trading queens because of his terrible pawn structure) Kxf7 42.g6+ Kg7 43.gh Kxh7 44.Kf2 <or 42.f4 Kg7 43.fxe5 dxe5 44. and the f5 pawn will fall> Kg7 45.Ke3 Bg5+ and again the f5 pawn falls. C.41.Qh6+! Kh8! 42.g6! Qg7 43.Qxh5 Kg8 44.gh+ Qxh7 45.Qe8+ Bf8 46.Qc8 (46.Qe6+ Qf7 ) and the position looks about equal. but black has the initiative i.e. Qf7 Qxa6 Qxf5 Ke2 e4 or something like that. i think its pretty clear that 38.Nh6 would be an error. 38.Nxe7 Qxe7 39.Qxg6 and the situaton is pretty grim for black. |
|
| Dec-23-05 | | Tariqov: <aginis>hmmm ok,Give me time to analyse with a board |
|
| Dec-23-05 | | aginis: i guess ill be back to check for your reply tomorrow. |
|
| Dec-23-05 | | simsan: <aginis> When I was trying to solve the puzzle, my idea after 36. Ra7 kh8 was the cool 37. Ng7 Bxg7 38.Ra8 (pinning the queen). Actually, the reason I think I found Ra7 was because I was looking for a way to pin the queen in the 8th rank (considering this week's theme). Looking at my computer it does however seem to suggest that both: 37. Qb7 Re7 38.Nxe7 Qf7 and
37. Nh6 Bxh6 38.gxh6 Nf6
... are stronger lines thant Ng7. |
|
| Dec-23-05 | | Cogano: Hi all. If everyone will forgive my ignorance, why is 26...Bxe7 bad? Alas,
my lack of experience continues to haunt me, & I presently have no means to remedy that. Thanks all for your patience, understanding & assistance. |
|
| Dec-23-05 | | Richerby: To 16 ply, Fritz 8 prefers ♖a7. I'm quite pleased that ♖b8, my guess at a solution (not in any way thoroughly analyzed), is Fritz's second choice. Further, Fritz thinks that Tarnowski could have defended rather more tenaciously. 1) 36.♖a7 ♕c8 37.♘h6+ ♗xh6 38.gxh6 ♘f6 39.♖a8 ♘xd5 40.♖xc8+ (+4.69) 2) 36.♖b8 ♕xb8 37.♕xe6+ ♔h8 38.♘h4 ♕b1+ 39.♗e1 ♕b7 40.♘xg6+ ♔g7 41.♘h4 ♕f7 42.♕xf7 ♔xf7 43.g6+ (+3.53) 3) 36.♘e7+ ♗xe7 37.♕xe6+ ♔f8 38.♖c7 ♕f7 39.♕c8+ ♔g7 40.♔g2 and the a-pawn will soon fall. (+3.19) |
|
| Dec-23-05 | | Richerby: <Cogano> 36... ♗xe7 is `bad' because it drops the exchange: 37.♕xe6+. But Fritz thinks this is the best defence nonetheless. |
|
| Dec-23-05 | | piteira8: I have a problem with 36. Ra7. If 36. Ra7, then 36. ... gxf5. Since the white knight is gone, black can close the seventh rank at e7. |
|
| Dec-23-05 | | Richerby: <piteira8> After 36.♖a7 gxf5 White wins the exchange with 37.exf5. |
|
| Dec-23-05 | | EmperorAtahualpa: <Richerby> I checked 36.Rb8 on Crafty, and it turns out it's also second preference there, although the difference is minimal. 36...Qxb8 37.Qxe6+ Kh8 38.Nh4 Qb1+ 39.Ke2 Qb7 40.Nxg6+ Kg7 41.Nh4 Qf7 42.Qxf7+ Kxf7 43.g6+ Kg7 44.gxh7 Kxh7 45.Bg5 Kg7 46.Nf5+ Kf7 47.Kd3 Ke6 48.f4 exf4 49.Bxf4 (eval +4.29; depth 17 ply; 200M nodes)
So Crafty's preference order of moves at White's 36th move is just like Fritz: 1: 36.Ra7 (eval +6.16; depth 17 ply; 200M nodes)
2: 36.Rb8 (eval +4.29; depth 17 ply; 200M nodes)
3: 36.Ne7+ (eval +3.95; depth 17 ply; 335M nodes)
4: 36.Re7 (eval. +3.25; depth 17 ply; 137M nodes) |
|
| Dec-23-05 | | YouRang: Rats - didn't get it. I usually don't get Friday puzzles, but I usually at least CONSIDER the key move. Today, I didn't look at 36. Ne7+. :( |
|
| Dec-23-05 | | Averageguy: This game is Game 30 as "Board with Excitement" in Chernev's book "The Most Instructive Games of Chess Ever Played". |
|
| Dec-23-05 | | et9: i got 36.Re7 probably winning. |
|
| Dec-23-05 | | TheSlid: I also "got" 36.Re7, but since I have had Chernev's book for 30 years and still didn't "get" Ne7, that must be a fail. Drat! |
|
| Dec-23-05 | | ughaibu: TheSlid: Sounds like the game's not as instructive as it's cracked up to be. |
|
| Dec-23-05 | | simsan: I have a question to those of you who have the high-end digital chess engines. Are they any good at discovering pertpetual checks (for the player that seems to be loosing) thus evaluating those lines to 0.0? |
|
| Dec-23-05 | | TheSlid: You could be right <ughaibu>. I've been Bored with Excitement for years now. |
|
| Dec-23-05 | | ughaibu: Excitement, yeah, I remember that. |
|
| Dec-23-05 | | TheSlid: Excitement is best avoided - it usually leads to trouble. |
