|Jul-16-17|| ||Marmot PFL: Looks like Kramnik should have played 1 d4 yesterday.|
|Jul-16-17|| ||whiteshark: Fedo's queenside operation starting with <21...Nb6> ended in a disaster in a minimum of time|
|Jul-16-17|| ||iking: nice win ..|
|Jul-17-17|| ||Captain Hindsight: <Marmot PFL: Looks like Kramnik should have played 1 d4 yesterday.> I couldn't have said it any better.|
|Jul-17-17|| ||ChessHigherCat: Was 25. a3 really played? I was looking for the mysterious mating threat if 25...QxB can't find it:|
25. a3 Qxb3 26. Qg3 g6 27. Qh4 h5 28. Qg5 Kh7
Or 25. a3 Qxb3 26. Rg3 g6 27. Rxg6+ fxg6 and black's queen guards f7
|Jul-17-17|| ||fisayo123: <2720+> Fedoseev isn't exactly hopeless vs 1. d4 Just a bad day at the office.|
|Jul-18-17|| ||malt: Agree with <chessHighercat> 25.a3, there was 25.Re4 Qa5 26.B:a4 or 25.B:f7+ K:f7 26.fg7+ Kg8 27.Ne4|
|Jul-18-17|| ||beatgiant: 25. a3 Qxb3 26. Qg3 g6 <27. Qf4>, and now Black's ...h5 does not prevent Qh6. I don't see a good defense.|
|Jul-18-17|| ||PhilFeeley: White slapped that queen around pretty well.|
|Jul-19-17|| ||talwnbe4: after 25..Qxb3? 26. Qg3 it's forced mate..
26..g6 26.Qg5 Kh8 28. Re4 Rg8 29. Rh4 Qc4 30. Ne4 Qxe4 31. Rxe4 Nd5 32. Rh4
after 25..Qf8 black was losing badly 4.5
25. Bxf7+ is also strong 6.4
|Jul-19-17|| ||talwnbe4: 22. f5! immediately attacking realising the dark squares around Fedoseev's king are weak. Fedoseev's position was already bad.|
|Jul-19-17|| ||beatgiant: <talwnbe4>
Agreed, but after 25...Qxb3 26. Qg3 g6 27. Qg5 (or 27. Qf4) Kh8, I was looking at simply <28. Qh6> Rg8 29. Rd8 with 30. Qg7# next. I think Black can only delay that line a few moves by jettisoning a couple of pieces.
|Jul-20-17|| ||MuzioFan: <beatgiant> You are almost correct, black can choose to go down the hopelessly lost line 25...Qxb3 26. Qg3 g6 27. Qg5 (or 27. Qf4) Kh8 28. Qh6 <Qxd1+> 29. Nxd1 Rg8 and while the game is completely over there is no immediate mate (30. Rd3? Be6).|
|Jul-20-17|| ||beatgiant: <MuzioFan>
Thanks. I had seen 28...Qxd1+ in your line, but what I missed was at the end of it, if 30. Re4 (threatens Qxh7+/Rh4# or Rh4/Qxh7#) Black staves off immediate mate with 30...g5.
But even in <talwnbe4>'s line there must be ways for Black to drop pieces to prevent immediate mate - for example, what if 25...Qxb3 26. Qg3 g6 27. Qg5 Kh8 28. Re4 <Bg4>? Probably we have to check these with a computer.
Anyway, I think we've answered the original question about the <mysterious mating threat> that was not so mysterious for the players.
|Jul-20-17|| ||perfidious: I had spotted the line given by <beatgiant> which enables Fedoseev to survive a while with 30....g5, though surely Black is losing in the end, but found no forcing wind-up thereafter.|
|Jul-20-17|| ||morfishine: Deep game...
|Jul-21-17|| ||ChessHigherCat: <beatgiant: Anyway, I think we've answered the original question about the <mysterious mating threat> that was not so mysterious for the players.>|
Thanks, I missed 27. Qf4.
