Nov-29-05   goodevans: sorry, avidfan, but 40.Q2d7+ isn't legal so it's still unclear whether 38... Rc2 saves the game.
Nov-29-05   RookFile: Think we've got enough queens on the board for this one?
Nov-29-05   TopaLove: I think 40.Bh6+ wins too.
Nov-29-05   mymt: like <notsodeepthough> I went for 40.Bh6+ Kf7
if 40. ...Kg6 41.Q2g5+ Kh7/f7 42.Qg7#
41.Q2d7+ Kg6
if 41. ...Qe7 42.Q8xe7+ Kg6 43.Qg5#
42.Qg5#
Nov-29-05   Guest1825: Wow, I totally did not even understand this one! What I had was 39.Qe1, which gives checkmate after 39...Qg2. I thought that was the answer. These things are getting tougher.

  dakgootje: <Guest1825> Dont know whether i understand and/or interprate your post totally, but as the puzzle is 'White to play', and you have 39. Qe1 for white followed by 39. ...Qg2# where black mates. It isnt a very good sollution is it...Probably understand your post wrong..

  YouRang: The only thing difficult about this puzzle was that there was too much firepower. 39. Rxg7+ was easy to spot. After that, I considered 40. Q2d7+ and 40. Qg5+ and 40. Bh6+, assuming only one of them would work. I finally decided that all of them would work!
Nov-29-05   kvcs: Hmm, LOM [Little Ole Molly], got this right off.

I gave this via Cellphone call to <Ancr> [Founder of the Kxe6s VEREIN (TM) Chess Society. he says" "Easy game, anyone that misses this needs a remedial Chess 101 course pronto!"

Further, he suggests that anyone not "seeing" the solution, to set the a board up. Play the game until you get to move 25 for White. Study the position very well --- take it completely apart, Pawn by Pawn, Piece by Piece. This is the beginning of Lein's winning the full point right here. By move 30, White is well on the way to completing his plan --- Black is just along for the ride!! <Ancr> sums up: "Black could have Resigned on move #34!!"

It should be obvious within five minutes what White is trying to do. The game could conclude: 41 -- Qe7 42 Qe7+ Kg6 43 Qg5# Maybe LOM is "learnin" some Chess afterall!

Chessically speaking, just an 'ending' revelation....

KKKKKKKKKKKKK

Nov-29-05   svbabu: How about 37. ...Rc1+? Forcing white in many ways black would have had it.

  YouRang: <erimiro1: <Richard Taylor> You are not the real Richard, the one with the tie and glasses. I don't believe a word.> Somehow, the avatar that looks like a sewer demon doesn't quite go with the name, "Richard Taylor". It's an affront of avatar etiquette. ;-)
Nov-29-05   Guest1825: <dakgootje -39. e1 for white followed by 39. ...g2# where black mates.> yes, that's where I went wrong too!

  kevin86: I guess it's "Ladies' night" again. White gives up rook to smoke black's king out. With all the heavy artillary,the game is easily won.

User: dakgootje says: "...Well the position after 38. ...Rc2 looks pretty drawn. If i have some spare time today ill let have Fritz a look at the position.".

After reading you assessment of the position at move 38 for Black, I called <Ancr> back and had him look at the position again. He ran this through A3CP [A Certain Chess-Playing Computer] which supplied: 38 -- Rc2 [not your Rc2, this is A3CP own generated move -- ha!] 39 Rg7+ Kg7 40 Qg5+ Kf7 41 Qh5+ Kg8 42 Qg6+ Kh8 43 Qh6+ Kg8 44 Qh6+ Kh8 Draw.

Seems MCPA [Mr Chess Person -- Ancr]"...needs a remedial Chess 101 course pronto!" He commends you on your observation...just 16, huh? <KVCS> will be watching your progress.

Let everyone here know what FRITZ finds. Also, what Version or Number of FRITZ do you have?

Best, Molly

KKKKKKKKKKKKK

Nov-29-05   Halldor: At start I decided to find if White could mate by checking with every move, and thus I found the continuation as in the game in a few seconds.
Nov-29-05   TTLump: I have not studied the Queen's Indian opening and was wondering if someone could briefly educate me on the purpose of 12.g3?
Nov-29-05   Guest1825: <<<<TTLump>>That's a great question, I'm very poor at openings, no memory.

Not to answer your question but I'd say "pity the poor knight". >>

Nov-29-05   TTLump: <EmperorAtahualpa> - good catch! 38... Rc2! saves the day for Black and ChessMaster agrees, with the result being a draw by threefold repetition at move 46.

Interestingly, the scoring after each move remained at 0.00 or -0.00. I think the four Queens got ChessMaster confused or perhaps it saw the forced draw 8 moves ahead?

  YouRang: <chessgames.com: Here's an extra tactical puzzle for you. How should Black proceed if White had played 38.Kh2?> 38...Qh1+! 39. Kxh1 Qxe4+ 40. Kg1 Rc1+! 41. Kf2 Qg2# (unless I made a mistake...)
Nov-29-05   likestofork: Hmmm, pick off a pawn with 38....Q1xe4, or pin one of the opponent's Queens to his king with the 38....Rc2 suggested by <EmperorAtahualpa>? After the pin, I don't see anything better for white than 39 Rxg7+ Kxg7 followed up by the perpetual checks in the northeast.

I thought poisoned pawns were only something swallowed in the opening?

  chessgames.com: <YouRang> 38...Qh1+!! yes, that's exactly the move we found as well.
Nov-29-05   TTLump: <likestofork> 1/2 is better than 0!

  YouRang: In the <chessgames.com tactical puzzle>, I notice that the line I gave previously isn't *quite* black's best defense (not that it matters). Black could survive one extra move: 38...Qh1+!
39. Kxh1 Qxe4+
40. Kg1 Rc1+!
41. Rf1 Qh1+ (Rf1 is the slight improvement)
42. Kf2 Qg2#

  patzer2: The puzzle solution 39. Rxg7+! is a decoy pseudo-sacrfice which allows the two White Queens a quick mate.
