Jan-04-23		Messiah: Interesting!

Jan-05-23		LoveThatJoker: The game ends with 43...f6!, and not 43...Rf6? when White wins. The game ends with a draw. Therefore, 43...f6 is the move. I will advise CG. LTJ

Jan-05-23		Messiah: <LoveThatJoker: The game ends with 43...f6!, and not 43...Rf6? when White wins. The game ends with a draw. Therefore, 43...f6 is the move. I will advise CG. LTJ> I LOVE when there is crap in the database!

Jan-05-23		Messiah: I also LOVE how the game score is corrected, but the engine annotation still shows 43...Rf6.

Jan-05-23		LoveThatJoker: <Messiah> Once again, thanks for your and <MissScarlett's> efforts here! It is all very strange, but yes the game is still wrong. 43...f6 should be the final move of the game. LTJ

Jan-06-23		LoveThatJoker: GOTD: The Art of the Half-Point LTJ PS. Named after the book by IM Leonid Verkhovsky - which I am presently reading - where I came across this gem for the very first time. A brilliant finish by White!

Jan-06-23		stone free or die: <<Messiah> I also LOVE how the game score is corrected, but the engine annotation still shows 43...Rf6.> Obviously, the computer annotated score takes a special run on the computer to generate which is not done automatically when the game score is updated. The old annotated score should probably should be deleted when the score is updated, and a request for a new annotated version automatically queued up. .

Jan-06-23		LoveThatJoker: <stone free and die> I agree. What is important now is to have the technical department manually correct this computer annotated version; as "computer annotated version" CG users who come to this game for the first time will be utterly befuddled as to why such a game is worth inclusion in ANY database. I am presently talking to someone who contributes to CG to help fix this...because, alas, this is a fiasco. LTJ

Jan-06-23		stone free or die: Yes, LTJ, it can all be a bit confusing, agreed. I did leave a message over on the <chessgame.com> support forum calling attention to this problem. chessgames.com chessforum (kibitz #39890) <Missy> isn't really a techie - the current admins who need to address this issue are these steve and pete: petemcd85 chessforum stevemcd87 chessforum I believe they're brothers hired by <Susan Freeman> (mother of "<Daniel Freeman>", the founder and main author of <chessgames>). <Pete> is usually the contact person, as I think <steve> prefers to work more behind the scenes (or perhaps they think it best to have a single contact person?).

Jan-06-23		LoveThatJoker: <stone free and die> I just wrote Pete on his forum on the matter. Thanks, man! Sincerely, LTJ

Jan-10-23		goodevans: A game that got more interesting as it went on. The finish is rather exquisite. The SF annoations give us 44.Bxf6 Rxf6 45.gxf6 Nb5 46.f7 Nd4+ 47.Kd3 Ne6 48.f5 Kb1 click for larger view But what follows is really rather beautiful, 49.fxe6 a1=Q 50.f8=Q Qa3+ 51.Qxa3 stalemate. Having said that, there are alternatives to 47.Kd3 worth exploring. I wonder to what extent both players considered these and whether a draw was just the most acceptable conclusion to a hard day's work.

Jan-10-23		An Englishman: Good Evening: Exciting struggle. 35.Bb2 looks like a clever swindle to induce 35...Kb3--would 35...f6 or 35...g6 improve? Don't overlook Black's own little trap. After 32...Ra4+; 33.Kf5,f6 White faces two threatened checkmates.

Jan-10-23		LoveThatJoker: <goodevans> I think that what you have said is right on the money: upon playing the moves in the final position, both players simply calculating a few more moves ahead, and kind of smilingly agreeing a draw here. Smilingly in the knowledge that the struggle has been both intense and one-of-a-kind. In my opinion, the draw agreement only adds to the already massive value this game holds. This said, I am very grateful for your added analysis as I hadn't come to appreciate that, should the game had been played on, it would have ended in such an intriguing stalemate! All in all, and to say the least, this game is truly very special - and to say the most, a credit to our wonderful game! LTJ

Jan-10-23		LoveThatJoker: <An Englishman> Very nice observations regarding 35. Bb2, and the possible mates after 32...Ra4+ 33. Kf5 f6. For the record, here are Verkhovsky's annotations to the game (with the diagram after Black's 36th. move, he writes), "In this apparently hopeless position White, as a result of an error by Black, found a unique way to save himself. 37. Ke3! Kb2?? Black wins after 37...Nd5+! 38. Kf3 f6! 39. g5 Rxh4 40. gxf6 Rf4+ 41. Ke2 h5, etc. 38. Kd2!! By sacrificing his rook White finds a very special draw. 38... Kxa1 39. Kc2! Rc4 40. g5 Rc7 41. h5 Rc8 42. h6 Rc6 43. f4 f6! Otherwise White could play for a win with 44. f5! followed by 45. g6!. Now the game is drawn because of 44. Bxf6 Rxf6 45. gxf6 Ne2! 46. f7 Nd4+ 47. Kc1 Ne6 48. f5 Nf8 49. Ke2." LTJ

Jan-10-23		LoveThatJoker: PS. "49. Ke2" I actually copied verbatim from the book without realising the author's/publisher's [LTJ: Russell Enterprises] egregious typo. Of course they meant "49. Kc2".
