| Jul-29-21 | | Brenin: White's K-side fortress is only just holding, so let's throw in another attacker with 28 ... Re3, threatening 29 ... Rxg3+ and mate next move. The R can't be taken, since 29 fxe3 Qxg3 is mate, attacking the Q with 29 dxc or 29 Nc4 is too slow, and 29 Nf3 or Bf3 simply lose a piece, so 29 Kh2 seems be forced. Now let's throw in another attacker with 29 ... f4, to open the f-file and the b8-h2 diagonal. This looks good enough to win, but it's bed-time and I'm too tired to calculate further. |

| Jul-29-21 | | Tiggler: Nice solution. I was seduced by Rxe2, but that probably does not work. |
|
| Jul-29-21 | | Refused: Ok, failed to get it.
Thought it might be something along the lines of 28...Rxe2 in combination with cxd4-d3. 28...Re3 is ofc a very neat shot, adding more pressure on g3. Really nice Talesque game by Najdorf. Ignore the hanging piece (on g5) and just put another piece on offer. |

 | | Dionysius1: Very nice. It seems good players recognise the weaknesses of squares/coloured networks of squares as quickly as I do pins and forks and skewers. Can anyone recommend good reading on this business of weak squares and how to take advantage of them? |

 | | drollere: missed this one too. focused too much on Nh3+, the a8 diagonal and f4 as the elements of attack. failed to see that e3 was available. |

 | | An Englishman: Good Evening: Thought ...f4 would win, and it seems as if it does, but perhaps more slowly. |
|
| Jul-29-21 | | Stanco: I solved it.
29.Re3 actually tends to open the route for the queen to mate if taken while also, of course, threatening to take on g3 with mate. If black plays 29...Kh2 defending g3 pawn, then 30. f4 and rook can't be taken because it follows 31.fg3+ Kg8 32.Nh3# which is the main line in my opinion.
The line 30...f3 (as played in the game) is hopeles for black. |

| Jul-29-21 | | TheaN: I'm with the f4 club, which is obviously a lot worse than Re3. It works on queen sac based levels, ie, 30.dxc5 fxg3 -+ threatening Nh3# is clearly winning However, always consider the regular acceptance of a sac: 29....f4 30.hxg5 fxg3 and we're in a very complicated position. SF remains cold however and evaluates +2 as all White pieces are close enough to defend. |

 | | Diademas: Nope. Not even close. |
|
| Jul-29-21 | | Cellist: Re3 is brilliant. I missed it. I wanted to play Qd5 with threat of mate. It seems that this also works - by winning a piece: 28. ... Qd5 29.Bf3 Nxf3+ 30.Qxf3 Qxf3 31.Nxf3 Bxf3 32.dxc5 Rd8 33.c6 Rc7 34.Rc3 Be4 35.Rfc1 Rdc8 36.f3 Rxc6 37.Rxc6 Bxc6 38.b4 g6 39.b5 Bb7 40.Rxc8+ Bxc8 41.a4 Bd7 42.g4 Kg7 43.gxf5 gxf5 44.Kf2 f4 45.Kg2 Kf6 46.Kf2. The obvious answer 29.f3 is worse than giving up a piece according to the engine (-4.64), but the follow-up is too complex for me to have found it. |

 | | agb2002: Black is one pawn down.
White threatens hxg5 and dxc5.
The black queen aims at g3. This suggests Nh3+ (followed by Nxf2), f4 and Re3. The only promising option seems to be 28... Re3: A) 29.fxe3 Qxg3#.
B) 29.hxg5 Rxg3+ 30.Kh2 Rg2+ 31.Kh1(3) Qh2#.
C) 29.dxc5 Rxg3+ as in B.
D) 29.B(N)f3 Nxf3+ wins decisive material.
E) 29.Kh2 f4
E.1) 30.fxe3 fxg3+ 31.Kg1 Nh3#.
E.2) 30.gxf4 Rh3+ 31.Kg1 Rh1#.
E.3) 30.hxg5 fxg3+ 31.Kh3 (31.fxg3 Qxg3#; 31.Kg1 gxf2+ 32.Rxf2 Qg3+ and mate next) 31... gxf2+ 32.B(N)f3 (32.Kg(h)4 Qg3+ 33.Kh5 Qh3#) 32... Bxf3 is winning. E.4) 30.f3 fxg3+ looks very bad for White. For example, 31.Kg2 Ne6 32.dxc5 Nf4+ 33.Kg1 Rxe2 34.cxd6 Nh3+ 35.Kh1 Rh2#. |

The alternative 28... Nh3+ looks unnecessarily complex after 29.Kh2 Nxf2 30.Rxf2 f4 (the rook on f8 x-rays the rook on f2) 31.Kg1 and the f-pawn is pinned. |

| Jul-29-21 | | belgradegambit: I call moves like Re3 “mouse slip” moves because they initially look like the kind of thing you see in blitz all the time. |
