Black to move. How should Black proceed?
Source: ChessToday.net
Black should “Shirov” White’s knight with 1…Rxd4! 2.cxd4 Bxd4+, when White’s king is “Dunne for,” e.g. 3.Kh1 Ng3+ 4.Kg2 Re2# or 3.Kg2 Re2+ 4.K moves Ng3#.
1. … Rd4: sure looks crushing. All White’s pieces are far away, and can’t help his King. Even Black’s Nh5 turns out to be brilliantly placed!
I suggest:
1. Rxd4
If now white takes:
1. … cxd4
2. Bxd4+
then it is mate in two more moves:
a) Kh2/g2 Re2+ Kh1/f1 Ng3#
b) Kh1/f1 Ng3+ Kh2/g2 Re2#
If white not takes with cxd4, there is the threat:
2. Rd1 double check Kh1/f1
3. Re2# (taking queen was not an issue here)
I can’t see how white defends this threat, without running into one of the mentioned lines.
1. … Bxf7+ K somewhere
doesn’t help either.
1. … Rxd4
white can´t take the rook back because of
2. cxd4 Bxd4+
and the next two moves will be Re2 and Ng3, check and mate. the move order depends on where the white king goes to. the only way white can prevent this from happening is to resign or sacrifice the queen on e3. greets, jan
1. Rxd4 cxd4 2. Bxd4+…. Kf1 or Kh1 3. Ng3+ Kg2 4. Re2+#
2…. Kg2 3. Re2+ Kf1 or Kh1 4. Ng3+#
1 Rxd4 looks like the only try, as after …cxd4, 2 Bxd4+, the white king is boxed in by the bishop, rook, and knight, and is mated by Ng3 and Re2 (which ever one is check is played first).
A small correction, if:
1. Rxd4 Bxf7+ (only attempt to prolong the game with some moves)
then it certainly isn’t K somewhere as I suggested, it is of cource:
2. Kxf7 Qxf4+
3. Rxf4 discovered +
and the rest goes after mentioned lines with Ng3 and Re2.
I think it is a mate in 5.
1….Rxd4! 2.cxd4 Bxd4+ 3.Kf1 Ng3+ 4.Kg2 Re2 mate or 3.Kg2 Re2+ 4.Kh1/f1 Ng3 mate or 3.Kh1 Ng3+ 4.Kg2/h2 Re2 mate
My idea is Rook takes Knight, because White cannot take back, otherwise it will be mated by Black pieces.
Well, I’m not sure but if White instead decide to move another piece, a discovered check grabs the White Queen.
Move the King seems to enter in a mate net, that’s it.

1…Ng3 trapping the king.
What a surprise, Shirov down a queen for a rook and on the attack.
Well, the first things I would look at here are the exchange sacrifice at d4 or the simple check with the rook on the g-file, or some combination of those ideas. I would chose the exchange sacrifice first mostly because it is the most forcing way to open up the line for that wonderful bishop at c5.
1. …..Rd4
2. cd4 Bd4
White has four moves-Kf1, Kg2, Kh2, Kh1. Let’s take them in order:
3. Kf1 Ng3
Chosen to force the white king off the first rank so that the rook can join the fray on rank two, but even I can see mate arrives at the same time:
4. Kg2 Re2#
Or, at move 3:
3. Kg2 Re2 (plays itself)
4. Kf1
Of course, Kh1 is mate after Ng3. Continuing:
4. …..Ng3# anyway.
Or
3. Kh2 Re2
4. Kh1 Ng3#
Or
3. Kh1 Ng3 and mate on either of the two possible king moves for white at move 4.
Clearly, white cannot accept the sacrifice offer on move 2, but it doesn’t matter since the only options are to give up the queen at e3 or c2 (to discovered attack) and/or the bishop at f7, and I doubt either of them prevent mate more than 1 or 2 additional moves, if that.
