| Jan-24-19 | | ChessHigherCat: Not even close, oh well. I admit it was way over my head because I would have scored terribly in Guess The Move for both players. |
|
| Jan-24-19 | | Swapmeet: 32.Rc1 is a very natural looking move but the more subtle point is that black has no good Queen moves. 32...Qd6 33.Qb5 leads to total collapse. |
|
| Jan-24-19 | | BxChess: <ChessHigherCat:> In your line 32. Nxh5 Rxh5 33. Rxf7 Rxe3 34. Qc2 Qe6 perhaps better for black is 34...Qd6. This pins the g3 pawn, threatening RXh4, as well as also attacking it with the rook. Black seems to have quite some counterplay. 35. Rf8+ doesn't seem to lead anywhere. |

| Jan-24-19 | | Walter Glattke: 32.-Qd6 33.Qb5 Rc8 34.Nd3 Rxf3 35.exf3 Bxe3 36.Rxc8+ 1 piece, 32.-Qb6 33.Nxd5 Rxe3 34.Nxb6 Rxd3 35.Rxf5 gxf5 36.exd3 Bxb6 R for B. If 32.Nxh5 I prefer 32.-Rxg3 33.Rxg3 gxh5. |

| Jan-24-19 | | goodevans: <Swapmeet: 32.Rc1 is a very natural looking move but the more subtle point is that black has no good Queen moves.> An excellent point, the subtlety of which was lost on me as I searched for something more dramatic. Black can break the pin eventually but it will cost him another pawn (he's already one down): <32...Rc8> Attempting to relieve her majesty of her defensive duties. <33.Qc2> Implementing a "laser" pin on both Q and R. <33...Rf6> Now if white does nothing the pin is broken. <34.Qd2> Restoring the pin. <34...Qa6> Finally breaking the pin but leaving white a choice of how to capture the d-pawn. |
|
| Jan-24-19 | | Swapmeet: <goodevans> It’s even worse. After 32...Rc8 33.Nd3 wins a piece, I think. |
|
| Jan-24-19 | | schachfuchs: Strange puzzle - nil points for me >:-/
btw: At first I didn't realize that white is the Indian GM Vidit just playing the Tata Steel Masters. |
|
| Jan-24-19 | | TheaN: Not really sure where CG is heading with their puzzles in some late examples. 32.Rc1, winning, is not really a puzzle. It was my pick for lack of something better, but it's no sacrifice, no real combination (just overworking the Queen basically). Black underestimated White's position after opening up the c-file and payed for it. Nothing more or less. I'm okay with it <if> it's clear some positions don't necessarily involves sacs or deep combinations but it's a first where something like this has been used. |

| Jan-24-19 | | agb2002: White has a knight and a pawn for a bishop.
White can pin the bishop with 32.Rc1 (32.Qc3 Qb6): A) 32... Rc8 33.Qc3
A.1) 33... Rf6 34.Nd3
A.1.a) 34... Rxf3 35.exf3 wins the bishop.
A.1.b) 34... Be7 35.Qxa5 Qb(d)7 36.Rxc8+ Qxc8 37.Rxf6 Bxf6 38.Qxd5 + - [N+3P vs b]. A.2) 33... Rxf3 34.exf3 followed by Nd3 as in A.1.a. A.3) 33... Qd6(7) 34.Nd3 as above (34... d4 35.exd4). B) 32... Qb6 33.Nxd5 followed by Rxf5 wins decisive material. C) 32... Qd6 33.Qb5 Rc8 34.Nd3 wins the bishop. |
|
| Jan-24-19 | | goodevans: <Swapmeet> We've got our wires crossed somewhere... After <32.Rc1 Rc8> it isn't possible to play 33.Nd3 yet until Her Majesty moves, but after <33.Qc2 Rf6> 34.Nd3 doesn't win a piece because the B is no longer pinned. |
|
| Jan-24-19 | | goodevans: <agb2002> Is it me or is it everyone else today? I've just queried <Swapmeet>'s last post and now your line <A.2> looks impossible to me. After <32.Rc1 Rc8 33.Qc3> (i.e. your <A>) it isn't yet possible to play <33...Rxf3> because white hasn't played Nd3 yet. You might like to consider <A.4>: 32.Rc1 Rc8 33.Qc3 <Qc7>, intending to break the pin with <34...Bd6>. |
|
| Jan-24-19 | | Swapmeet: <goodevans> My mistake! I was looking at Rc8 after having inserted Qd6/Qb5 ala my original post. No more posting before coffee. |

After <32.Rc1 Rc8 33.Qc3> (i.e. your <A>) it isn't yet possible to play <33...Rxf3> because white hasn't played Nd3 yet.> You're right. I probably messed up some lines while 'dumping' my memory on the post. <You might like to consider <A.4>: 32.Rc1 Rc8 33.Qc3 <Qc7>, intending to break the pin with <34...Bd6>.> I would replace my A.2 with this line, which somehow questions 33.Qc3 instead of 33.Qc2 directly, because after 33... Qc7 34.Qc2 Bd6 35.Qxf5 White seems to end up two pawns ahead: 35... gxf5 36.Rxc7 Rxc7 37.Nxd5. |

| Jan-24-19 | | King Harvest: @TheaN <Not really sure where CG is heading with their puzzles in some late examples. 32.Rc1, winning, is not really a puzzle. It was my pick for lack of something better...> 100% -- I agree.
I'm opposed to complaining about something free especially when it's something that I've enjoyed on and off for many years... I'm not going to start complaining now... if I have to adjust my expectations so be it... That said, everything you said in your post makes perfect sense to me. |

| Jan-24-19 | | landshark: Anybody else look at 32.Qc3? It pins the B and also threatens 33.Nxh5 with lots of threats such as Rxf5 or Qg7#. 32... d4 fails to exd4
32... Rxf4
33.Rxf4 Rxe3
34.Qc2 seems winning
32... Qd6 looks best, possibly the refutation:
33. Nxh5 Rxh5
34. Rxf7 Rxh4+ This is the resource I missed
35. Kg2 d4 Followed by a nice clearance sacrifice
36. exd4 Qd5+ and White's house is crashing down - Not an easy line to find in 'puzzle solving' mode. This was an interesting study and even though I didn't get the right solution I don't mind having to look this far to see where I went wrong - |
