White to move. Is this a win or draw?
8/8/8/8/K7/1R3p2/1N6/1k3r2 w – – 0 1
1.Nc4+ Kc1 2.Ra3 wins the Rook
if 1…Ka1 2.Ra3+ etc…
Let me start the ball rolling…
1.Nc4+ Ka1
2.Ra3+ Kb1
3.Nd2+ wins the rook.
1… Ka2 is similar. 1…Kc2 allows fork.
1.Nc4+ Kc1
2.Ra3 (threatening skewer) Kb1
3.Nd2+ forking K and R
or 2…Kc2 (Kd1) 3.Ne3+ fork
1.Nc4+ Kc1
2.Rc3+ Kd1
3.Ne3+ Ke2
4.Nxf1 Kxf1
5.Rxf3+
Nc4+ looks good, with a knight fork coming.
h
1 Nc4 wins.
A: 1… Ka1(or Ka2) 2 Ra3 Kb1
3 Nd2+-
B: 1… Kc2 2 Ne3 +-
C: 1… Kc1 2 Ra3 ! and Black can not prevent the loss of his rook:
1) 2… Rf2 3 Ra1 Kc2 4 Ra2
2) 2… Rd1 3 Ra1 Kc2 4 Ne3
3) Any king move and White forks the king and rook- 2…Kc2 or Kd1 and Ne3+; Kb1 runs into Nd2.
-Justin Daniel
Win for white after 1. Nc4+ Kc1 2. Ra3!
b
Nc4+ should win by eventually forking black’s K and R. After NxR if Black can play KxN, White plays RxP.
