|Jul-31-18|| ||malt: <once> Sad to hear about Daniel Freeman.|
|Jul-31-18|| ||patzer2: <Once> Thanks for letting us know of the passing of CG co-founder Daniel Freeman. I only knew him by correspondence, which was always cordial and professional, and by the great product he produced here on a daily basis.|
My sympathies to his friends and family. Even though I was only a customer and fellow member, I will miss him.
|Jul-31-18|| ||saturn2: <Once> Got it now. Sorry.|
|Jul-31-18|| ||Richard Taylor: It may have been easy. I found the first move but then failed to find a win...|
Yes it is sad about Daniel Freeman.
|Jul-31-18|| ||Richard Taylor: By the way I suspect Kotov just took a risk as with a King in his camp he decided there would be sure to be some way to win, whether it was forced is another matter...|
|Jul-31-18|| ||AlicesKnight: <malt> - <once> and others - agreed. Thank you Daniel Freeman.|
|Jul-31-18|| ||zb2cr: The only reason this could be considered "easy" is that the game is so famous. Many of us have seen it before, and remember at least 30. ... Qxh3+; 31. Kxh3, Rh6+; 32. Kg4, Nf6+ at least and that repetition of moves was available.
Not all of the details of the King hunt need be found.|
|Jul-31-18|| ||gawain: Because this is presented as a puzzle I was willing to sac the queen, on spec, for the sake of the king hunt. There was nothing else to try. I would never have found the right path over the board, though.|
|Jul-31-18|| ||Sally Simpson: Hi Gawain,
"I was willing to sac the queen, on spec..."
" I would never have found the right path over the board, though."
Don't worry about it. Kotov sacced his Queen on spec and did not find the win OTB.
From moves 33 to 40 Kotov repeats the position taking a pawn on move 38 to avoid a three fold rep. The game was adjourned at move 40 and Kotov worked out the win from his hotel room.

|Jul-31-18|| ||unrepentant: Wouldn't 33. Ng4 lead to a much faster mate? I think the maximum would be mate in 4.|
if 33. ... Ng4 34. Kg4 Rg8+ 35. Kf5 Rf6 mate
if 33. ... Ng4 34. Bh4 Rf8+ 35. Bf6 Rf6+ Kg4 36. Rg6+ and Rh5mate
if 33. ... Ng4 34. Bh4 Rf8+ 35. Kg4 Rh4 mate
Did I make a mistake?
|Jul-31-18|| ||PJs Studio: One of my favorite games. Think like a super Grandmaster.|
|Jul-31-18|| ||swclark25: <unrepentant> problem with 33...Ng4 is white can respond with 34.Nxf4. Per Stockfish, even this move favors Black (-4.61 at 29 ply), but white is still not mated through move 54.|
|Jul-31-18|| ||Howard: But doesn't Bronstein state in his very well-known book that 33...Ng4 would have been better, anyway?|
|Jul-31-18|| ||gawain: Thanks <Sally Simpson> I saw that Kotov was repeating moves to get to time control. Which naturally means home analysis! (I hadn't thought about that.) That does make me feel better.|
It is also some consolation to hear that <Sargon> is picking up the chessgames.com reins.

|Jul-31-18|| ||unrepentant: SWClark25, Thank you! I missed that obviously.|
|Jul-31-18|| ||FrogC: It's a famously brilliant, and hence difficult, combination.|
|Jul-31-18|| ||1stboard: What does white do if black plays 33 Nh5 ??
Looks like all sorts of threats for black... Rf8 , Rg8 , etc ( not to mention potential discover check on h file by black .....
Am I missing something ??
|Jul-31-18|| ||reti: My condolences to the family of this site webmaster. He truly developed a wonderful site, where people can share their opinions and knowledge of the game. It is also sad to read that he was only 51 years old. Very sad day, indeed.|
|Jul-31-18|| ||JohnBoy: I donít see how snagging the d5 pawn, mid combo, helps black. It just seems to add options for white.|
|Jul-31-18|| ||shivasuri4: <1stboard>, both 33...Nd7 and 33...Nh5 win for Black. 34. Rg5 is the expected reply for either move.|
<JohnBoy>, perhaps Kotov was attempting to merely reach the time control without having a three-fold repetition occur.
|Aug-01-18|| ||Sally Simpson: Hi JohnBoy,
Kotov, apparently in time trouble, 'snagged' the d5 pawn to avoid repeating the position so he could reach move 40 and seal.
The instructive move is the Queen sacrifice because looking at the following moves it is obvious Kotov did not work it our before playing it, he did it on intuition.
I suspect Kotov saw he had at the very least a perpetual so went for it. This is a very common ploy..I've used it and so has Botvinnik.

(I've just mentioned me and Botvinnik in the same sentence!)
|Aug-01-18|| ||CHESSTTCAMPS: An obvious king hunt opportunity, where attention to detail is needed:|
30... Qxh3+!! and now
A. 31.Kxh3 Rh6+ 32.Kg4 (Bh4 Rxh4#) Nf6+ 33.Kf5 (Kg5 Rh5#) Nd7! (key move to keep the king contained) 34.Rg6 (otherwise 34... Rf8+ 35.Kg4 Rg8+ 36.Kf5 Rf6#) Rf8+ 35.Kg4 Rxg6+ 36.Kh5 Rg5+ 37.Kh4 (Kh6 Rbg8 and mate next) Rbg8 38.(any) Rg4+ 39.Kh5 R8g5+ 40.Kh6 Bf8#
B. 31.Kg1 Rh6 32.Be1 Qh1+ 33.Kf2 Bh4+ 34.Ng3 Bxg3+ 35.Nxg3 fxg3+ 36.Rxg3 Rh2+ wins a rook plus a minor piece.
B.1 32.Bg3, B.2 32. Bh4, and B.3 32.Be3, the moves that give the WK an escape square, all toss a bishop immediately, with more losses to follow.
Still, I'd rate this problem higher difficulty, even if the direction of the solution is clear at first inspection.
|Aug-01-18|| ||CHESSTTCAMPS: I thought it was TLAGM. Regardless, I missed the game defense (34.Rg5 instead of Rg6) and therefore the key component of the complete solution. It would still be a challenging exercise to redo, even after seeing the end of the game played out.|
