Black to move. What is the best way for Black to proceed?
Bd4+, gives discovered check and black has 3 options:
Kf1 leads to Ng3#
or
Kh1 leads to Ng3#
so best is:
Kf3, Rf2+ gives black 2 options:
Ke4 leads to Ng3#
so best is:
Kg4, Ne3+ will force an eventual 3-fold repetition of position and a draw no matter where the White Kings moves.
1.Be3+ is probably winning: 1.-Kf3 Rf2+ 2.Ke4 (2.Kg4 Rf4+ 3.Kh5 Rh4++) Rf4+ 3.Kd3 Rd4+ followed by Bxg5 with material advantage, and black is attacking.
Greetings from Toronto.
Nh4 Kh1 Bg3 Qa5 then White has many ways to mate but can also just play Re1.
Nh4 Kh2 Be1 Kh1 Bg3 transposes
1…Nh4+ 2. Kf1 and where are those checkmating threats? Ra2 3. Nf7 Nf5 4. Nd6 +-
1… Bd4 2 Kf3 Rf2 3. Ke5 Ng3 4. Kd3 uncl
1… Be3 2. Kf3 Rf2+ 3. Ke4 Rxf4+ 4. Kd3 Rd4+ 5. Kc2 Bxg5 -+
I think Black wins after 1. … Be3+
1. … Be3+
2. Kf3 (Kf1 or Kh1: 2. … Ng3#)
2. … Rf2+
3. Ke4 (2. Kg4 Rxf4+ 3. Kh5 Rh4#)
3. … Rxf4+
4. Kd3 Rd4+
5. Ke2 Bxg5
There are still some things to do, but Black is winning.
