|Feb-03-12|| ||James D Flynn: I really like morfishline's idea 26...5. I found it superbly counter intuitive. What if White doesn't take on e5? Say 27.Rcf2 g5xf4+ 28.Rxf4 Ng6 and Black can pile up on the pinned R on f4 and the White K is quickly mated if it tries to move.|
|Feb-03-12|| ||Once: <Memethecat> Couldn't really comment on houdini as I've never used it. Looking back over my multiple Fritz's it seems that one of the reasons I keep changing is to keep up with the new operating systems that microsoft likes to inflict on us every few years. Then there's the new training functions like the video thingie that was introduced around Fritz 10. Now there's a new "Let's check" feature in version 13 which claims to generate an internet database of positions and evaluations...|
<BOSTER> has a little hobby of disagreeing with me whenever he can. Most of the time I just ignore it. It's not really worthy of a comment and everyone needs a hobby, I suppose. But every now and again it gets so silly that I can't resist responding in kind. As you say, a little bit of history.
|Feb-03-12|| ||gofer: White has lost control of the a7-g1 diagonal and as such its king is in a mating net. Black simply
needs to blast through the remaining defenses with Rxh2+, but really black would like to follow up
with Qh4# rather than Ng4+ or Rh8+, but the DSB is in such a good position that white is fighting
for its life!
<25 ... Rxh2+>
<26 Kxh2 Rh8+>
<27 Kg3 Qd8/Qe7>
The mating net is complete. Black threatens Qh4#. Black must find an escape square for the king
as there are no checks available...
<28 fxe5 Qg5+!>
The funniest part of the next continuation is that white starts to entomb his own king, as his king
cannot run away! 29 Kf6 Qe3+ 30 Kg5 Bxe5 mating with either Qg3# or f5+ mating!
<29 Bg4 Qe3+>
30 Rf3 Bxe5#
<30 Bf3 Bxe5+>
<31 Kg4 f5#!>
A very nice finish indeed!
|Feb-03-12|| ||gofer: <29 Kf6 Qe3+ 30 Kg5 Bxe5 mating with either Qg3# or f5+ mating!>|
I did see <31 Rxf7+>, but I didn't analyse it... ...just plain old lazy I suppose!
|Feb-03-12|| ||jackpawn: I found the line most others found: <29 Kf6 Qe3+ 30 Kg5 Bxe5 mating with either Qg3# or f5+ mating!>. What is strange to me is that we all found 29 .. Qe3+, but not the game text of 29 ..Qf5+. Now why is that? I would like to think in a game that once I reached that point I would find the cleaner move of 29 ... Qf5+. Maybe that's what Kudrin did too.|
|Feb-03-12|| ||LoveThatJoker: <jackpawn> I found the text move.|
|Feb-03-12|| ||jackpawn: <LoveThatJoke> chuckle. Okay, most of us found 29 .. Qe3+. :)|
|Feb-03-12|| ||LoveThatJoker: <jackpawn> It's LoveThatJoker. |
|Feb-03-12|| ||SuperPatzer77: <<jackpawn> It's LoveThatJoker.>|
<JackPawn> Batman's oldest nemesis is Joker. LOL. I'm rooting for Batman. <LoveThatJoker> is rooting for Joker. LOL LOL.
Maybe <LoveThatJoker> likes to use two playing cards - Jokers. He sure as heck can take me to the cleaners. LOL LOL.
|Feb-03-12|| ||squaresquat: you people are thieves and cheats. it's a sad thing to be so lacking in virtue. You charged me. I go to Java and punch buttons. you people fence me out because of my verbal mastery and your rhetorical ineptitude.|
|Feb-03-12|| ||ChessNewbie55: too easy for a friday.|
|Feb-03-12|| ||1stboard: Looks like white should have played Qxb6 on move 20. Funny White did not ( swap Queens )considering he tried to swap queens a few times up to that move and black was avoiding.|
|Feb-03-12|| ||Penguincw: If I were playing in a casual game, I would play 25...Ng4.|
|Feb-03-12|| ||Patriot: White threatens 26.fxe5.
Given the white king's lack of mobility, I want to play 25...Rxh2+:
25...Rxh2+ 26.Kxh2 Rh8+ 27.Kg3 Qe7 28.fxe5 Qg5+
A) 29.Kf3 Qf5+ 30.Ke2 Qe4+ (30.Kg3 Bxe5+ 31.Rf4 Qxf4#) 31.Kd2 Qe3#
B) 29.Bg4 Qe3+ 30.Bf3 Bxe5+ (30.Rf3 Bxe5#) 31.Kg4 Qf4#
I think this is it. I had a really tough time visualizing this.
|Feb-03-12|| ||paulalbert: Like many others, I visualized to Qe3ch, but Sergei's Qf5ch obviously cleaner and more direct, so I'll give myself only partial credit.|
|Feb-03-12|| ||CHESSTTCAMPS: In this opposite-colored bishop middle game, material is even, but white has too much force offside on the queen-side,leaving a lightly defended king that faces a semi-open h-file for black. White threatens fxe5 and probably expects a knight retreat, but the knight is nicely positioned to assist a lethal attack. I had this pretty fast, I thought, but then I found a hole in my original analysis and had to come back later to find the right line.|
Black's control of the dark squares leaves the WK little room to run. Nonetheless, this needs to be calculated carefully from the puzzle position.
26.Kxh2 Ra1+ and now
A) 27.Kg3 Qe7 (threatening Qh4#) 28.fxe5 Qg5+! (wrong is Qh4+? 29.Kf3 Qh5+ 30.Ke4! Qxe5+ 31.Kd3 holds!) 29.Bg4 Qe3+ 30.Bf3 (Rf3 Bxe5#!) Bxe5+ 31.Kg4 f5#!
A.1) 28.Rh1 Rxh1 29.fxe5 Qg5+ 30.Bg4 Qe3+ is similar to main line.
A.2) 29.Kf3 Qe3+ 30.Kg4 Qe4+! 31.Kg3 (Rf4 Bxe5!! 32.g3 f5+ forces mate) Bxe5+ 32.Kf2 Bd4+ 33.Kg3 Qe3+ 34.Rf3 (or Bf3) Be5+ 35.Kg4 f5#!
B) 27.Bh5 Rxh5+ 28.Kg3 Qe7 29.fxe5 Qg5+ 30.Kf3 Qe3+ 31.Rf3 (Kg4 Rg5+) Bxe5+ 32.Kg4 f5+ 33.Rxf5 exf5#
Lesson learned: sometimes, the biggest problem in analysis is not the visualization, it's getting a fixed idea in your head, such as the parenthesized note at black's move 28 in line A.
|Feb-03-12|| ||CHESSTTCAMPS: I missed the much simpler 29... Qf5+ of the game.|

The rook sac on h2 is crying out to me. Let's start with...
25...Rxh2+ 26 Kxh2 Rh8+ 27 Kg3 Qe7
28 fxe5 Qg5+ 29 Kf3 Qe3+ 30 Kg4 f5#
I think this must be it. Time to check.
Aw, nuts! The f-pawn can be captured en passant. This is real sloppiness on my part. No excuse.
|Feb-03-12|| ||LIFE Master AJ: I spent about 20+ minutes on this one.

The position after 25.f4.
click for larger view
I saw 25...RxP/h2+; almost immediately, but thought my attack would run out of gas, I even saw the one line that gave <dzechiel> trouble.
So I tossed out the Rook-sack, and spent quite a bit of time, looking for "something else." However, after many minutes of looking, I came back to the obvious sack, (there really was nothing else); and said: "I must be missing something ... somewhere down the line."
At first, I did not want the WK to cross the f3 sqaure, I thought that this meant that White was getting way. However, after MANY minutes of analysis, I had a MAJOR insight (a big flash of inspiration).
THE PATTERN that suddenly reached out and grabbed me was that it was GOOD for Black to get the WK to e2 and d2!!!!! One e2, its a classic epaulette mate, and on d2 a sneaky epp. mate.
Once I realized the TRUTH of the position, it became a simple "cattle drive," and all too obvious. However, I will easily and frankly admit that I did NOT come to the EASY and OBVIOUS mate ... not without a lot of work and calculation!!!!!
More and more lately, I am reminded of my good friend - of many years ago. (We are still friends - just now he lives far away, and no longer plays chess avidly as he did during the 1970's.)
"Chess analysis is a like lot mining ... you don't find anything worthwhile on the surface, the deeper you dig, the more nuggets you find."
- (J.) Scott Pfeiffer.
For all you younger whipper-snappers (who may live in this area) and don't know the name, Scott was - at one time - probably the best player on the Gulf Coast. When I was still just a fish and struggling to learn anything about the game, Scott could bowl me over with his pinky, and won tournament after tournament. In fact, I knew that I had finally "come of age" (chessically speaking) when I began to hold my own with this player.
|Feb-03-12|| ||BOSTER: <FSR> <Na4- what was white thinking ?>.|
It's not easy to read the thoughts of players.
But many believe that style in chess as a mirror reflects player's personality.
White position is difficult.
Black has a center, the opened h file, active pieces.
Playing knight on a4,( everybody knows that knight on the edge is not good) white continues the chasing black queen, attacking pawn c5 and protecting his pawn on b2. But white has clearly understand that after this move the mobility of the white queen is very limited.
Playing very sharp b4 white could create the play on the queen's side, because black need at least couple moves to use the weakness on h2.
This is the pos. 22.with b4 (instead Kh1)

Maybe white wanted to play 22.Nxc5, ,but then didn't decide this.
|Feb-03-12|| ||TheBish: W Doubleday vs Kudrin, 2004|
Black to play (25...?) "Difficult"
25...Rxh2+! 26. Kxh2 Rh8+ 27. Kg3 Qe7 28. fxe5 Qg5+ 29. Kf3 Qf5+ 30. Kg3 (30. Ke2 Qe4+ 31. Kd2 Qe3#) Bxe5+ 31. Rf4 Qxf4#.
Of course, White can throw away a piece or two more, but mate is the end result.
|Feb-11-12|| ||morfishine: <James D Flynn> Thanks for the comments! I really appreciate it. You pointed out one of the reasons for 26...g5: It opens up <g6> for the knight|
