Black to move. How should black proceed?
Source: ChessToday.net
1. … Bg4
2. Kd2 (best move) Qd1+
2. Kc3 Bf6+ and the rest is technique as they say
1. …. Bg4
2. most moves on the board Qd1#
Mark
1…Bf6 is very strong. Threatens Bc3. Hence Knight is forced to control the c3 square
One possible variation:
1… Bf6 2. Nb5 Kxh8 3. Bg2 Qg4 4. Bf4 Bd3 5. Bf1 Qd7 6. Bxd3 Qxd3 and black wins
Bg4 Qd1 & Bf6
There is no defence against Bg4, which leads directly to mate.
i think black can win the rook without giving the bishop and Bf6 should be the right move, it threatens the Rh8, but there are several possible answers:
2. Rc8 Bg4
3. Rc1 Bc3+
4. Bd2 Qe4+
5. Be2 Qxe2#
or
2. Rd8 Bc3+
3. Rd2 Bg4
with Qd1# to follow.or
3. Bd2 Qe4+
4. Be2 Bg4
5. f3 Bxf3
6. Rg2 Bxd2+
7. Rxd2 Bxg2
or
4. Kd1 Bg4+
5. Kc1
ok, that`s all folks, i can`t finish the job, hope i was on the right track.

Well, I thought intitially that Bg4 might be the right approach, but after Rd8, I don’t quite find a good continuation for black:
1. …..Bg4
2. Rd8
I looked at Kd2 here, but after Qd1 and Bf6, I think white is going to lose both the knight at a3 and the rook at h8 and has a decisive material disadvantage, and that is assuming I am not missing a mate in that line for black. Continuing:
2. …..Bf6 (what else now?)
3. Nb1 Qb7 (eyeing b4)
4. Nd2 Qc7 (eying d8 and c1)
5. f3
The only defense I see for white. Continuing:
5. …..Qd8
I looked at this a long time, but don’t see anything better for black here but this move, and after white takes at g4, white stands a bit better materially, and if he can get his pieces coordinated, might even have a win.
Now, with Bg4, the other move that catches the eye is Bf6 to threaten Bc3. This move fails in the line above because white has time to get the rook off h8 and time to play f3. Now white is pressed for time:
1. …..Bf6
2. Nb1
If white plays Nb5, black will still continue with Kxh8. I will cover 2.Be2 later. Continuing:
2. …..Kh8
3. Nd2 Qc6
And, I don’t see any quick mates here, but maybe I am missing something. However, black has saved the bishop, won the h8 rook, and has a queen for a rook and knight on net- a decisive edge in most circumstances, and probably the case here, too.
Finally, at move 2 in this line, white can try a more complicated defense with 2.Be2:
1. …..Bf6
2. Be2 Bc3
3. Bd2
If white plays Kf1, black will mate starting with Bh3. If white plays Kd1, Qd5+ followed by Kh8 will be sufficient to win. Continuing:
3. …..Bd2!
4. Kd2 Qa3
And now, white needs to save the rook at h8. The only squares of retreat are e8, d8, b8, and a8, but none are truly safe due to the exposed white king:
5. Re8 Qb4
6. Ke3
If white plays to the 1st rank, black can win the g2 rook with Qb1+. Continuing:
6. …..Qc3
7. Kf4 Qd4 with mate on the next move.
Or, at move 5:
5. Rd8 Qa5 wins the rook at d8.
Or, at move 5:
5. Rb8 Qd6 wins the rook at b8.
Or, finally, at move 5:
5. Ra8 Qb4 and once again, black will either mate on 6.Ke3, or win the rook at g2 instead.
I will accept 1…Bf6 is strong. as,
1…Bf6 threat is Bc3# 2.Be2 seems to be better. but,
2… Bc3+ 3.Kd1 Qd5+ If
4.Kc1 Qxa2 threat is QxN+ or Qa1+
5. Bd3 BxB
6. Rb8 QxN+ White can’t avoid huge material loss. Or…
4.Bd3 QxB+ 5.K any, Kxh8
Black has huge advantage.
