| Sep-23-18 | | Delboy: The bishop sac 34. ... Bxg2+ followed by 35. ... f3 is both aesthetically pleasing and deadly. Note that 37. Kg1 f2# is mate. Alternatives also lose for white, e.g. 36. Qd5+ Kh8 37. Qd2 fxg2++ 38. Kg1 Rf1+ 39. Rxf1 gxf1=Q+ 40. Kxf1 Qf3+ followed by 41. ... Ra1+ |

| Jan-13-22 | | Honey Blend: 34. ♕c4+ ♔h8 35. ♕e2 would have been the better defense for White to avoid the attack that happened in the text. |

| Jan-13-22 | | Brenin: 34 ...Bxg2+ 35 Kxg2 f3 36 Bh1 Qh3+ (not 36 ... f2 37 Qg2 or Bg2) 37 Kf2 (otherwise 37 ... f2+ follows) Qh2+ 38 Ke3 Qe2+ 39 Kd4 Rfd8+ 40 Kc5 Qxe4, with Q for B and mate to follow soon. |
|
| Jan-13-22 | | Refused: 1...Bxg2 2.Bxg2 f3 is the first only thing that comes to mind. a)3.Bxf3 Rxf3+ ends the game immediately
b) 3.Bh3 Qxh3+ once again the endis near
c) 3.Bh1 Qh3+ 4.Kf2 Qh2+ (4.Kg1 f2# 4.Ke1 f2+ curtains) 5.Kf1 Qxh1+ 6.Kf2 Qh2+ 7.Ke3 Qe2+ 8.Kd4 Rd8+ I am somewhat missing the instant kill after the outright rejection of the Bishop. 1...Bxg2+ 2.Ke2 |
|
| Jan-13-22 | | Brenin: After allowing his K's defensive wall to be breached with 13 ... Bxc3 14 bxc3, White's 16 Qxb5 was unwise, exposing both K and Q to attack; 16 Bxb5 would have been safer. It is then instructive how Black manages to avoid Q exchanges and to open lines for his pieces. |

click for larger viewHe will be an exchange down and the position is quite ugly, but the fight will be far from over. |
|
| Jan-13-22 | | Brenin: <Refused>: After 34 ... Bxg2+ 35 Ke2 I think that 35 ... Ra5, or possibly 35 ... Bxf3+ 36 Qxf3 Ra5, wins for Black, though nothing like as clearly as in the game line. |
|
| Jan-13-22 | | Brenin: <Honey Blend>: After 34 ... Bxg2+ 35 Bxg2 f3 36 Rxg7+ Qxg7 37 Bh3 Ra5, I don't think White can last long, e.g. 38 Rd5 Ra1+, or 38 e6 Rg5 39 Qe3 f2. |

| Jan-13-22 | | EasilyConfused: I think 35 Ke2 is a better move for White than the game line. 35.. Bxf3+ is OK but I think White can survive with precise play. |

| Jan-13-22 | | Refused: Brenin yes black is better in all lines. That is out of the question. Like I said, I just don't see the instant kill(s) like in the game line. Black can keep on pushing with Ra5 and the full point should drop eventually - personally, I wouldn't exchange pieces on f3, if I can avoid it as it feels like exchanges make white's defensive task some easier. With the exposed king I'd prefer keep attackers on the board. |
|
| Jan-13-22 | | AlicesKnight: I saw the ... Bxg2+ and ... f3 game line, but, like others (as I see now), thought White could do better not taking - Black remains better but not yet conclusive. Moving the B from the h3-d7 diagonal has perils for Black if checking slows down (Rxg7+ and Rd7+). |

 | | agb2002: Black is one pawn down.
The white bishop holds the position. This suggests 34... Bxg2+: A) 35.Bxg2 f3
A.1) 36.Rxg7+ Qxg7
A.1.a) 37.Bxf3 Rxf3+ 38.Qxf3 Rf8 wins.
A.1.b) 37.Bh3 Ra5 (37... Rae8 38.e6 with some resistance) 38.e6 (38.Rd5 Ra1+ 39.Kf2 Qg8#) 38... Rg5 must be winning. A.2) 36.Bxf3 Rxf3+ wins.
A.3) 36.Bh1 Qh3+
A.3.a) 37.Ke1 Qxh1+ 38.Kd2 Rad8+ wins.
A.3.b) 37.Kf2 Qh2+ 38.Ke3 Qe2+ 39.Kd4 Rad8+ wins decisive material. A.3.c) 37.Kg1 f2#.
A.4) 36.Rd2 Ra1+ wins.
B) 35.Ke2 Bxf3+ 36.Qxf3 Qh2+
B.1) 37.Qf2 f3+ 38.Kf1 (38.Ke1(3) Qxe5+) 38... Qxe5 looks very good for Black (39.Rdd7 Ra1+ and mate in two). B.2) 37.Ke1 Qxc2 and Black has won a pawn and looks better. B.3) 37.Kd3 Rfd8+ is surely too risky for White. |
|
| Jan-13-22 | | Viennablue: I looked into 34…Ra4. In case of 35. Qxa4 White gets mated (starting with 35…Qxf3+ etc).
Unfortunately White can refuse this Rook sacrifice leading to a level game… |

 | | Teyss: As <Refused>, I didn't see anything convincing after 35.Ke2 although Black has a winning position.
Interesting 36.Rxg7+ line provided by <Honey Blend> which I didn't consider: again Black is winning but not an immediate kill. |
|
| Jan-13-22 | | TheaN: I get the Thursday label, but CG is missing a rather tricky variation here. <34....Bxg2+> is free, as 35.Bxg2 f3 seems suicidal for White and it is. I had actually missed 36.Bh1 but it's obvious f3 will decide by taking away critical flight squares, 36....Qh3+ 37.Kf2 (Kg1 f2#; Ke1 Qxh1+) Qh2+ -+ and the White king's forced into the line of fire of the rooks. However, <35.Ke2> and Black has just won the pawn back he lost earlier. Black's winning but it's far from satisfying. I seriously considered exchanging twice on f3 but that seems hard to win (-0.48). I seriously looked at <35....Ra5 -+>, which is best apparently, to keep the White queen at bay and pressuring the position, yet there are moves like 36.Qc4+ to consider. Not that 'medium', the combination in full is, the variation approaches Saturday. |

 | | Dionysius1: <TheaN... However, <35.Ke2> and Black has just won the pawn back he lost earlier. Black's winning but it's far from satisfying>. Well, yes and no. Thomas the Tank (Engine)'s analysis implies bring the rooks into play, don't exchange bishops, and the open files and the initiative will be enough for a cast iron win. I agree it's not as satisfying as the line white allowed Black to play, but I'd be grinning if I was playing as Black. |

 | | benveniste: I saw the first two moves. I didn't see 36. ♖xg7+. Black ends up the exchange for a pawn, but with so many major pieces in an open position it's still going to be a fight. |
|
| Jan-13-22 | | Elbajacisback: I went for the flashy 34..Ra4 and black should win if the queen takes the rook, playing 35..Qxf3 etc. But what is the best play if the rook sac is refused? |
|
| Jan-14-22 | | Brenin: <TheaN>: After 34 ... Bxg2+ 35 Ke2 Ra5 36 Qc4+ Kh8 White has the B and the e-pawn both en prise (with check), and cannot avoid mate soon. |
