1. … Rc5! is kind of standard and looks winning here.
1Rc5 wins.
Rc5
White will not be able to stop promotion.
1. ..Rc5! 2. Ra6 c2 3. Ra1 c1=Q 4. Rxc1 Rxc1 winning the white rook.
If 2. Kxc5 c2, White has self-blocked the c file and made the black pawn unstoppable.
If 2. Rc6 Rxc6 3. dxc6 c2 4. c7 c1=Q, Black wins the pawn race and safely covers White’s queening square.
why 1. … Rc5 of course. 🙂
Rc5
1…Rc5 2.Kxc5
(2.Re6 c2 3.Kxc5 c1=Q+)
(2.Rb6 c2 3.Rf6+ Kg7 4.Kxc5 c1=Q+)
(2.Ra6 c2 3.Ra7+ Ke8 4.Kxc5 c1=Q+)
2…c2
3.Rd7+ Kg8
4.Rd8+ Kf7
5.Rd7+ Ke8
6.Kd6 c1=Q
7.Re7+ Kf8
8.Rh7 Qxg5
9.Kc6 Qg2
10.Kc5 Qc2+
11.Kb5 Qd3+
12.Kc6 Qc4+
13.Kd6 f4 and Black can exchange the queen for the promoted pawn and win
1…Rc5 wins. IF white captures with the king, it blocks the white rook for occupying the c file, and the pawn queens.
1….Rc5 looks winning, as the pawn must queen regardless of what Karpov does.
A kind of tactic I have used and had used against me over the board in online games more than once. Make white block his rook’s access to c1:
1. …..Rc5!
2. Kc5
Or [2.Rc6 Rc6 3.dc6 c2 4.c7 c1Q-+]. or [2.Rd7 Ke8-+]. Continuing:
2. …..c2 and the black pawn can’t be stopped any longer.
Rc5
I hope Seirawan found Rc5!
The basic idea is for Black to sacrifice his rook, thereby having
the White king block the White rook from stopping along the c-file the
Black c-pawn from queening.
1. .. Rc5 2. Kxc5
(2. Rc6 Rxc6 3. dxc6 c2 4. c7 c1=Q)
(2. Rf6+ 2. .. Kg7 (2. .. Ke7? 3. Kxc5 (3. Re6+ Kf7 4. Kxc5 c2 5. Re1) 3. .. c2 4. Re6+ Kd8 5. Re1) 3. Kxc5
(3. Rc6 Rxc6 4. dxc6 c2 5. c7 c1=Q) 3. .. c2 4. Rc6 c1=Q+ 5. Kb6 Qxg5)
(2. Rd7+ Ke8 3. Rh7 c2 4. Kxc5 c1=Q+ 5. Kd4 Qxg5)
2. .. c2 3. Rf6+ Kg7 wins. Black must avoid (3. .. Ke7? 4. Re6+ Kd7 5. Re1)
