Black to move and win. How should Black proceed?
Source: ChessToday.net
1..Bd4! 2.Qxd5? QxQ 3. RxQ Re1++!
or 2.Rxd4 Re1+! 3.Kf2 Re2+! 4.KxR Nxf4 5.Rxf4 QxQg2! and Black should win this
so there follows 2.Kh1 and here Re4! -+ closes the matter
This puzzle comes too soon since we’re all watching these games as they’re played. The answer here is Bd4 setting up a pretty strong discovered check. Black has an overwhelming attack.
Well, after looking at this for about 20 minutes, I finally found a move that effectively cuts communication between white’s rooks just long enough, maybe:
1. …..Bd4
2. Qd5 Qd5
3. Rd5 Re1 (double check)
4. Kg2 Rd1 and black is up a full piece.
Other replies by white lose, too, I think, but the hardest wins seems to be:
1. …..Bd4
2. Rd4 Re1
3. Kf2 Re2
4. Ke2 Nf4
5. Ke3 Qg2
6. Kf4 Qh2
7. Ke3 and the three connected pawns on the kingside should be enough to win this. Another main line in this variation is
5. …..Ng2
6. Kf2 Qc6
7. R7d6 Qc2
8. Rd2 and the knight must be lost anyway, but now white retains his h-pawn.
Best for white might be
1. …..Bd4
2. Rd4 Re1
3. Qf1 Rf1
4. Kf1 Ne3
5. Ke2 Qg2
6. Ke3 Qh2
Black’s king should find shelter on the h-file, but this could be long slog for black to bring home a win.
Honestly, I don’t see anything better for black than 1. …. Bd4, but see no easy wins here.
Just looking at the position again, I overlooked something that might be better in the last line for black- the line I was most concerned couldn’t be won:
1. …..Bd4
2. Rd4 Re1
3. Qf1 Ne3!
I looked at this move earlier, but dismissed it because it seemed to obviously lose to 4. Rd8 +, but I overlooked black’s correct reply, and just got stuck on the bad move Qd8.
4. Rd8 Kg7!! (Qd8?? 5. Rd8+-)
And the queen can’t be touched due to Rf1#, and the rook can’t be touched due to Qg2#. The best white can do is string it out by throwing material away after R4d7.
1. …, Bd4
2. Rxd4, Re1+
3. Kf2, Rf1+
4. Kxf1, Ne3+
Bd4
Rd4 Rf8
Kg2 Rf2
Kf2 Ng4 wins
1. … Bd4
* if
2. Rxd4 Re1+
3. Kf2 Re2+
4. Kxe2 Nxf4+
5. Ke3 ** Nxg2+
next, the black queen comes up, e.g., to e4, and black wins
** if 5. Ke2 Qxg2+
* or if
1. …. Bd4
2. Kh1 Re4
threatening
3. … Nxf4
4. Qf3 Re1+
and 5. … Qxf3+
0-1
1. … Bd4!
2. Qxd5+ Qxd5
3. Rxd5 Rd3+ and black is up with a bishop.
if white plays,
2. Rxd4 Re1+
3. Kf2 Re2+
4. Kxe2 Nxf4++ and black wins
So white should play,
2. Kh1 Re4! and this prolongs the game a little bit more plus it protects blacks hanging knight on d5 and gives black with a lot of attacking chances on white’s kingside.
1. … Bd4
For example:
2. Rxd4 Re1+
3. Kf2 Re2+
4. Kxe2 Nxf4+
5. Rxf4 Qxg2+
6. Rf2 Qc6
correction:
1. … Bd4!
2. Rxd4 Re1+
3. Kf2 Re2+
4. Kxe2 Nxf4+
5. Rxf4 Qxg2+
Black can capture some of white’s pawns and it should be ok to exchange the queen for white’s 2 rooks if it comes to that point. Black should win the end game.
