| Apr-05-23 | | jrredfield: I initially chose 32 d6, looking to spring a multi-prong attack with Bxb7, attacking both rooks and the Black N simultaneously. But after more analysis, I like 32 Rxg6. 32 Rxg6+ fxg6 33 Qf6 Qe3+ 34 Bxe3 Rf8 35 Qd4
There are quite a few winning moves for White here. d6, Re1, the text move Rfxa6 and a number of other less dynamic moves, but simply strong because White's position is so superior. |
|
| Apr-05-23 | | Brenin: It's very instructive how pressure from White's Q and two Bs, on adjacent diagonals, caused the collapse of Black's Q-side, and then White used his control of the centre to switch operations to the K-side. |
|
| Apr-05-23 | | Mayankk: My line was 32 Rfxa6 bxa6 33 Qf6 Kf8 (to safeguard against Qg7/Qh8#) 34 Qg7+ Ke7 35 Re1+ Kd8 36 Rxe8+, winning the Queen. The key was to see that the Rook was misplaced at f6 and White Queen rightfully belonged there. After that it was just a matter of finding the most forceful sequence to replace the f6 Rook with Queen. |

| Apr-05-23 | | King.Arthur.Brazil: I guess that potd is easier than yesterday. Although I though about g3, I would ask for something better and I didn't find it. Today, seems pretty obvious, since you give no chance for Black defense: 32. Rxg6+ hxg6 (of fxg6) 33. Qf6 with 2 mates: Qg7# or Qh8#, which can't be avoid simultaneously. |
|
| Apr-05-23 | | King.Arthur.Brazil: Before someone criticize my move: if Kf8 33. Rg8+ Kxg8 34. Qf6 Kf8 35. d6 as in the game, mate next! |
|
| Apr-05-23 | | agb2002: White has the bishop pair for a bishop, a knight and a pawn. The weak dark squares around the black king invite to play 32.Rxg6+: A) 32... hxg6 33.Qf6 Kf8 (33... Qf8 34.Qh8#) 34.d6 and mate soon. B) 32... fxg6 33.Qf6 and mate soon (33... Qf7 34.Qh8#). C) 32... Kf8 33.Qf6 as in A (33... Qd8 34.Rg8+ Kxg8 35.Qg7(h8)#. |
|
| Apr-05-23 | | Refused: Looking at the position
You really want the Queen where the rook is. So let's vacate the square for the queen. 32.Rxg6+
a) 32...hxg6 33.Qf6 Kf8 34.d6 curtains
b) 32...Kf8 33.Rg8+ Kxg8 (Ke7 34.Qf6) 34.Qf6
c) 32...fxg6 33.Qf6 Qf8 34.Qh8+ Kf7 35.Rf1 Ke7 36.Qe5+ was the toughest defense I could come up with |
|
| Apr-05-23 | | Mayankk: Maybe I am missing something, but how is 32 Rxg6+ fxg6 33 Qf6 Qe7 a quick mate ? 33 ... Qe7 prevents 34 Qg7# while 34 Qh8+ Kf7 is a much longer mating line. |
|
| Apr-05-23 | | saturn2: Clearing f6 for the queen by a sacrifice. Ra6 or Rg6+ |
|
| Apr-05-23 | | saturn2: By the way 32.d6 is good enough |
|
| Apr-05-23 | | saturn2: <Mayankk: Maybe I am missing something, but how is 32 Rxg6+ fxg6 33 Qf6 Qe7 a quick mate ?> I am not sure what you mean. 34.Qxe7 and mate next. |

 | | Dionysius1: I took with the R(a1) which works too, but not as quickly |
|
| Apr-05-23 | | AlicesKnight: I found both R6xa6 and Rxg6+ looking good; the game line is incisive. |

| Apr-05-23 | | TheaN: Put me in the <32.Rxg6+> group, which seems to end this a bit more forcefully. Two lines aren't as complicated: 32....Kf8? 33.Rg8+ (if we still have it, might as well use it) Kxg8 (Ke7 34.Qf6#) 34.Qf6 Kf8 (else Qg7#/Qh8#) 35.Qh6+ Ke7 36.d6+ Kd8 37.Qf6+ Qe7 38.Qxe7# and 32....hxg6? 33.Qf6 Kf8 34.d6 #4. I initially had 34.Qg7+ here which works too but allows the king to run a bit. The more difficult line is <32....fxg6 33.Qf6 Qf8> where the queen sort of comes to the rescue? White wins after <34.Qh8+ Kf7 35.Qxh7+ Ke8 36.Qxg6+!> shifting play to the light squares: 36....Qf7 37.Re1+ Kf8 38.Qh6+ Kg8 39.Qh8# doesn't work. <36....Kd8>. A lot wins here, I thought sticking to board control with <37.Bf6+ Kc7 38.Be5+ Kd8 39.Qg5+ Ke8 40.Re1 +-> was good enough. The key for the combination is the dark square control: an early d6 isn't even necessary as we can take away d8 and c7 simultaneously if the king runs, and when the entire king side falls the light squares are just as weak. The game line accomplishes this too and takes out a piece that might eventually come to help, yet it's not forcing. |

 | | scormus: My first thought was, how can I find the right move when there seem to be so many winning moves to choose from?
I thought about 32 R(either)xa6, Rfxg6+, but I rather fancied 32 d6.
Rtaher to my surprise, SF rates 32 d6 not quite as overwhelming as Rxg6+ but slightly higher then Rfxa6.
Raxa6 also nets a strong but not overwhelming advantage, ca. +5.5. W's position is so dominating that even nothing moves like 32 Kh1 of b3 maintain most of the advantage.
Are there any moves which don't win? The only "vaguely plausible" move that loses is 32 Rxf7?? which not only gives away R for p, but lets B out of jail. Despite the impressive evals of d6 and Rfxa6, Rxg6+ clearly looks the most positive route to victory. |

| Apr-05-23 | | Stanco: Obviously, I played 32. Rxa6 |

 | | Honza Cervenka: <Brenin: It's very instructive how pressure from White's Q and two Bs, on adjacent diagonals, caused the collapse of Black's Q-side, and then White used his control of the centre to switch operations to the K-side.> I agree. This is a nice game by Verlinsky. I think that black's troubles started from 14...Nxb3 played instead of more reasonable 14...Nbc6. Instead of 31.Qf1 white could have played also 31.Re6! fxe6 32.Qe5 Qd7 33.d6 Rf8 (preventing threat 34.Qh8+ Kf7 35.Qg7+ Ke8 36.Qg8#) 34.Bxb7 Qxb7 (or 34...Rb8 35.Bc6! +-) 35.Qh8+ Kf7 36.Qxh7+ Ke8 37.Qxb7 etc. |
