 | | al wazir: I got it, sort of.
After 48...Rf2+ I was expecting 49. Kd3 Bxe3 50. Kxe3 Rxb2. Comes to the same thing, except that black picks up the ♙ on b3. |

| May-27-20 | | Cheapo by the Dozen: Easier than Tuesday, truth be told.
Black is up a pawn but has 2 pieces hanging. The game line obviously appears to win material and, even if for some reason it didn't actually do so, it would lead to safe simplification. |
|
| May-27-20 | | agb2002: Black is a pawn up.
White threatens Kxd1 and Rxg6.
The black bishop x-rays d2 and e3 and the white bishop is defenseless. Therefore, 47... Rxd2+: A) 48.Kxd2 Rf2+
A.1) 49.Kd3 Bxe3 50.Kxe3 Rxb2 wins a piece.
A.2) 49.Ke1 Bxe3 50.Bc1 f4 wins a piece.
B) 48.Ke1 Rf1+
B.1) 49.Kxd2 Rf2+ transposes to A.
B.2) 49.Kxf1 Bxe3 50.Bc1 Rf2+ and 51... Bd4 wins a piece. |
|
| May-27-20 | | boringplayer: Even after 50)..Bc1; 51) Kf2 Bf4, Black is still winning, I believe. |

| May-27-20 | | Brenin: At move 43 Black controls the d-file, but White's N on f3 guards the entry point d2. Then with 43 h5 White invites his opponent to take over the g-file as well, and with 44 Nd2 he places the N on the square it was guarding. Presumably this was after the time control, so it is hard to understand such slack play. A few moves later we meet the puzzle, where is easy to seen that taking the N wins. |
|
| May-27-20 | | stacase: That's what I would have played over the board and I would have been very happy to accept White's resignation. |
|
| May-27-20 | | AlicesKnight: 47...Rxd2+; 48.Kxd2 Rf2+ picks up the White R on e3 and Black is up a piece. Te other white R has no counterplay to undermine the Q-side. |
|
| May-27-20 | | smitha1: Why 50... f4? Then White can play 51 Bxe3 fxe3 52 Rh3 and the pawn on e3 drops. Isn't 50... Bd4 better? |
|
| May-27-20 | | saturn2: Is there a statistic how many wednesdays start with check? Black has to pieces attacked but unwindes them 47...Rxd2+ 48. Kxd2 Rf2+ 49. Ke1 Bxe3 50 Bc1 (last attempt before resigning ) Bd4 51. Rh4 Rg2 |
|
| May-27-20 | | Brenin: <smitha1>: 50 ... Bd4 does indeed seem to be better than f4, since it avoids losing a pawn. Maybe Black, especially if he was short of time, was worried about allowing White counterplay with Bg5+ or Rh7+, though in fact these come to nothing. |
|
| May-27-20 | | morfishine: <Cheapo by the Dozen: Easier than Tuesday, truth be told> Agreed! |
|
| May-27-20 | | TheaN: Relatively easy Wednesday, definitely easier than yesterday. Black enters a rather forced line with <47....Rxd2+ 48.Kxd2> 48.Ke1 might actually be the most decent try but it's not better per se. I prefer the straightforward 48....Rxb2 49.Rxh6 Re4 -+ and Black simplifies to R+N vs R. But the point is <48....Rf2+> where Re3 is pinned, so Black's is going to win it back with the knight interest. <49.Ke1 (Kd3 Bxe3 50.Kxe3 Rxb2 -+) Bxe3 50.Bc1> perhaps White's final try to entice Black to go B+N vs R, but after <50....f4 -+> we will trade down to R+N vs R and it's game over. Interestingly to discuss what's better, 50....f4 or 50....Bd4? IMO, f4 for humans, Bd4 objectively. f4 simplifies at the cost of a pawn (51.Bxe3 fxe3 52.Rh7+ Kd8 53.Rh3) whereas Bd4 keeps the material but allows White some counter play after 51.Bg5+. Simplification is usually favored in practical play so that's why I went with f4. |
|
| May-27-20 | | TheaN: A practical line after 50....f4, showing the rather triviality even after throwing the f-pawn is 51.Rh7 Kd8 52.Bxe3 fxe3 53.Rh3 Ne8 54.Rxe3 and now either Rh2 to block White from entering the Black camp or Rb2 to keep perpetual pressure on Pb3 work well. |
|
| May-27-20 | | TrollKing: I went with 47 ... Rxd2+
48 Kxd2 Rf2+
49 Ke1 Bxe3
50 Bc1 Bxc1
51 Kxf2 Bf4
with a B, N, + 2 P for the Rook. Stockfish says it is only slightly worse than the game continuation. |
|
| May-27-20 | | Damenlaeuferbauer: After long pondering, my old Georgian friend Mikhail finally found 47.-,Rxd2+ 48.Kxd2,Rf2+ 49.Ke1 [49.Kc1/Kd1/Kd3,Bxe3(+) -+] 49.-,Bxe3 50.Bc1,f4 or 50.-,Bd4 -+. This is how to play with black against the lame King's Indian Attack in the Sicilian. |
|
| May-27-20 | | Pedro Fernandez: Well, 47...Rxd2+ 48. Kxd2 Rf2+ 49. Ke1 Bxe3.

With additional N+P, I would win this with ease. |
|
| May-27-20 | | Pedro Fernandez: This is a massacre:
50. Bc1 f4 (I didn't put above this couple of moves because of they are obvious) 51. Rh3 Rc2 52. Bxe3 fxe3 53. Rxe3 Rc3, etc.
