|Jan-16-11|| ||VincentL: "Insane"
Material effectively equal.
Continuing with the theme of the week, this surely starts 20.....Rxh1+ (this is the only
move which is really forcing).
If black declines the rook with 21. Kg2, then Rxe1 followed by cxd4 and black emerges a
So 21. Kxh1. Now black has a choice. The logical move is 21....Qh8+, but since it is Sunday,
the apparently inferior Be4+ might be the continuation, or there could be some other ingenious
For now letīs go 21...Qh8+ 22. Kg1.
We have to stop Nxf5+, and for this reason I think the next move must be 22...Be4. (I see
no value in Bg4).
After 23. Nf3 I think something like 23.....Qh3. With this move, black eliminates
the usefulness of a subsequent Nh4 by white against Rh8, since black will be able to play
How can white prevent mate on h1 after Rh8 and Qh1+?
It appears that he cannnot, so 23. Nf3 is not a viable defence.
The only other possible try is 23. f3 (any other move results in an immediate Qh1 mate.
I think again in this line 23....Qh3 is the move we want. Now if 24. fxe4 Qxg3+ 25. Kf1
(or 25. Kh1 Rh8 mate) Rh8 26. Nf3 Rh1+ 27. Ng1 Rxg1 mate.
This seems to exhaust all possibilities.
Seems too easy for a Sunday - I have probably missed some clever defensive resouce.
|Jan-16-11|| ||VincentL: The game line is 21..... Be4+ and almost every poster also gives this.|
But I do not see why my 21....Qh8+ does not work, as in the analysis I give.
Perhaps I am blind somewhere.
|Jan-16-11|| ||Jimfromprovidence: <caissafan1963> <On the 21. Kg2 line (refusing the sac) Black continues with 21. ... Be4+, 22. f3 Qh3+, 23. Kf2 Rh2+, 24. Ke3 Qxg3.>|
I agree that 24...Qxg3, below is better than 24...Re8.

Now, the black bishop is safe for two reasons. 1). because the f pawn is now pinned and 2). if 25 Kxe4, then 25...Rh4+ 26 Kd3 Rxd4+ wins the queen.
In addition, since the white king has no escape squares the discovered check threat after 25...Re8, is now a mate threat. White probably has to give up give up a piece with 25. Ne6+ to prevent this scenario.
|Jan-16-11|| ||scormus: I dont expect it forced but I quite like 20 ... Rxh1+ 21 Kxh1 Be4+ 22 f3 Qh3+ 23 Kg1 Qxg3+ 24 Kf1 Rh8 25 e3 Bd3+ 26 Qxd3 (anythinge2 Rh1#) Rh1+ 27 Ke2 Qxe1#|
Now to see what happened
|Jan-16-11|| ||scormus: Wow, and I like Be3+ better than Bxf3. OK so everyone agrees it was easy for a Sunday, but that wont stop me bragging to my work colleague tomorrow ;-)|
|Jan-16-11|| ||CHESSTTCAMPS: In this middlegame position, white is temporarily up a piece for a pawn and likely planned for the automatic capture 20... cxd4 21.Qxd4, with the queen getting a commanding spot that works for defense and attack. But black's control of the all-important open h-file suggests that black can whip up a killer attack there, setting set aside such minor concerns as minor pieces.|
20... Rxh1+! allows the BQ to enter white's weakened castled position with gain of tempo. White's defensive options are limited:
A) 21.Kxh1 Be4+ 22.f3 Qh3+ 23.Kg1 Qxg3+ 24.Kf1 Rh8 forces mate.
A.1) 22.Kh2 Qh8+ 23.Kg1 Qh1#
A.2) 22.Nf3 Qh3+ 23.Kg1 Rh8 forces mate
A.3) 22.Kg1 Qh3 23.f3 Qxg3+ transposes to main line.
B) 21.Kg2 Be4+ 22.f3 (22.Nf3 Qh3#) Qh3+ 23.Kf2 Rh2+ 24.Ke3 Re8! (cxd4+ 25.Kxe5 is difficult to crack) 25.fxe4 cxd4+ 26.Kxd4 (Qxd4? Qxg3+ picks up a rook) Qxg3 and the double threat of Rh4 and Qe5+ is decisive.
Time to review game and kibitzing.
|Jan-16-11|| ||CHESSTTCAMPS: I should have carried line A a bit further.
<Gofer> <So I don't think white has to accept! Why is no one looking at Kg2 more closely??? I think the sac refusal is Sunday level. (The acceptance of the sac is more like a Wednesday/Thursday level!!!) ...>
I had similar thoughts as I reviewed the kibitzing from the top.
<JumfromProvidence> Agreed, in the refusal line, 24... Qg3 is sharper, though both should win easily. I looked at Qg3 first and missed the win of the WQ after 25.Kxe4.
|Jan-16-11|| ||Patriot: Black is currently down a piece for a pawn but this hardly seems to matter. I kept looking for something that even remotely compares to 20...Rxh1+ and could find nothing--not even 20...cxd4 which was presumably expected.|
20...Rxh1+ is dying to be played here.
A) 21.Kg2 Be4+
A.1) 22.f3 Qh3+ 23.Kf2 Rh2+ 24.Ke3 looks horrible for white considering the other rook can swing over to e8.
A.2) 22.Nf3 Qh3#
B) 21.Kxh1 Be4+
B.1) 22.Nf3 Qh3+ 23.Kg1 Rh8 and mate is unavoidable.
B.2) 22.f3 Qh3+ 23.Kg1 Qxg3+ 24.Kf1 Rh8 looks crushing.
B.3) 22.Kg1 Qh3 and either 23.f3 Qxg3+ transposing to B.2, or 23.Nf3 Rh8 transposing to B.1.
|Jan-16-11|| ||Sneaky: Easiest Sunday ever, I guess we get a late xmas present.|
|Jan-16-11|| ||scormus: I was not sure whther 21 Kxh1 or Kg2. Several people have commented that the fabric of W's K position is already badly eaten away. I suppose 21 Kg2 would have been the lesser of two weevils ;-)|
|Jan-16-11|| ||WhiteRook48: I chose 20...Rxh1+ but missed everything else.
It's good I did not evaluate material, otherwise I probably would have taken the knight
|Jan-16-11|| ||Lennonfan: <sneaky>i agree...i couldn't even get the previous thursdays yet i get sundays within a minute!!|
|Jan-16-11|| ||1.e4effort: for a Sunday, this is not really "insane". I got the first few moves, didn't spend a lot of time looking for the continuation - football on the tube y'know!!|
|Jan-16-11|| ||patzer2: Playing it out against <David2009>'s crafty endgame trainer (colors reversed), the win I found was 20...Rxh8+ 21. Kg7 Be5+ 22. f6 Qh6+ 23. Kf7 Rh7+ 24. Ke6 Qxg6! 25. Ne3+ fxe3 26. Qc6 Bc3 with an extra piece and two pawns up for an easy win.|
Haven't run it through Fritz yet to see if there's anything better, but it seems easy enough.
|Jan-16-11|| ||SpoiltVictorianChild: Very easy. Got the entire text line in under a minute.... Didn't examine many variations, but it looked solid enough to go for it.|
|Jan-16-11|| ||rilkefan: <25. Ne3+ fxe3 26. Qc6 Bc3>|
Wish I knew how to force it to not choose 25.Ne3, which seems about the easiest line to play against.
|Jan-16-11|| ||wals: Not even close. 21.Kg2 was a spoiler.
Rybka 4 x 64.
d 16 : 4 min :
22.f3 was #7.
1. (-#7): 22...Qh3+ 23.Kg1 Qxg3+ 24.Kf1 Rh8 25.Qh6+ Rxh6 26.Ne6+ fxe6 27.e3 Qxf3+ 28.Rf2 Rh1#
Black blundered, 25...Bxf3, -17.60.
Best, Bd3#, -#3.
White blunder, 26.Nxf3, -#2.
Best, Qh2, -17.60.
1. (-#2): 26...Qxf3+ 27.Kg1 Rh1#
|Jan-16-11|| ||gofer: I think that if you saw
<20 ... Rxh1>
<21 Kg2 Be4+>
<22 f3 Qh3+>
<23 Kf2 Rh2+>
<24 Ke3 Qxg3!!>

Then you can call this one solved... ...like a few others is played 24 ... Re8 into a winning end game
but Qxg3 is deadly and clearly winning as white has to give up the knight with Nf5+ or Ne6+ to avoid the

|Jan-16-11|| ||Lennonfan: <E4effort> im presuming you mean soccer and not the american game where you throw an oval shaped ball about with ur hands whilst dressed in a crazy suit with a helmet,and all you have to do is get it over a 50 yard line to score 6 points/goals?? Lol
If you mean footy then dont blame yer get watching...liverpool play everton today,i wont tell you result incase you do mean soccer!|
|Jan-16-11|| ||1.e4effort: <lennonfan>i did mean the American gladiatorial sport, although i love the beautiful game played with the feet. they finally added euro football channels on the tele over here, hallelujah! and the city i live in is right next to Akron, where Akron University is. Their team won our college championship. And, on a side note, I am a huge fan of John Lennon.|
|Jan-16-11|| ||M.Hassan: "Insane" Black to play 20....?
Black is up by a Knight for a pawn.
I worked so hard on this puzzle. Studied two different lines in depth, could not reach good results because by mistake i had put a Knight for Black sitting on d7 on my practice board!!!.My original material count was: Black is up by a pawn.Anyways, I found the right combination after wasting some precious time and then quickly could see the attack line:
and Black has the winning line.
|Jan-16-11|| ||TheBish: A Teloeken vs G Welling, 1996|
Black to play (20...?) "Insane"
I didn't find this particularly difficult -- not insane at all.
20...Rxh1+! 21. Kxh1 Be4+!
This move is the key, to clear the path for the queen to go to h3.
22. f3 Qh3+ 23. Kg1 Qxg3+ 24. Kf1 Rh8 25. e3 Bxf3 26. Nxf3 Qxf3+ and 27...Rh1# to follow.
There are a couple of minor variations, but this is the longest lasting defense.
|Jan-17-11|| ||Lennonfan: <e4effort>then you have an excellent taste in music as well as liking the beautiful game...the only european leagues worth watching are the spanish and english,the italians overated in my opinion,and the dutch and french leagues etc..are weak!|
|Jan-17-11|| ||BLarsen1967: <Lennonfan> I read that Magnus Carlsen is a Real Madrid supporter,oh,I bet Shirov is an FC Barcelona fan (spectacular football & spectacular chess!) - Anand,btw,he's more into cricket|
|Jan-17-11|| ||Lennonfan: <Blarsen1967> well im siding with shirov on this one then,barcelona play the best football iv seen in my lifetime at the moment..messi,iniesta,xavi,etc...best team in europe by a mile|
