With Black threatening both … Kxb8 and … Qa3+, 1. Bd4 answers both: 1. … Qg5 2. Qb3 d5 3. Rg8 (preparing 4. Qb8) Bc8 4. Bxa7. Now Black avoids immediate loss only by throwing material in the way.
I can’t find any clear solution to find a mating sequence…. im sure i can take a peice after a few moves but nothing is coming to me that is substanial..
White is two pawns down (even if this isn’t relevant at the very moment but it will soon count ) but has a very active rook. If he was to make his queen participate in the attack he would have very dangerous threats….
But 1.Qa6 ? Kxb8
So 1.Bd4!
Black here and later could sacrifice the queen for the bishop a tempo and then take the rook but White would be clearly ahead
1….Qd5 2.Qa6!
Now the queen enters the field since the rook is immune (2…Kxb8 3.Bxa7+ et caetera )
2….c5 3.Qxa7+ Kc6 4.Qb7 mate
Black could make a tricky attempt by 1….Qg5! 2 Qa6 d5!
Now 3.Bc5? fails on 3…Kxb8 4.Bxa7+ or 4.Qxa7+ because the bishop can’t perform both tasks of trapping the king and delivering the mate
but White can correct his idea with 2.Qb3 d5 3.Bc5 but here also 3…Bc8! sets problems or 3.Bb6+ Kd6 !
so 2.Ne4! Qd5 3.Qa6! wins since it prevents both the d5 and the Bc8 defences but Black still has something !
2….Qf5! so 3.Qb3! (3….Bc8 4.Rxc8+ ) 3….Qf1+ 4.Ka2 Bc8 5.Rxc8+! and White is (finally) a piece up !

I like 1.) Bd4 …
1. Bd4
With Black threatening both … Kxb8 and … Qa3+, 1. Bd4 answers both: 1. … Qg5 2. Qb3 d5 3. Rg8 (preparing 4. Qb8) Bc8 4. Bxa7. Now Black avoids immediate loss only by throwing material in the way.
Tough one… I don’t see any good continuations, but the Nd4 would be something I would play in a blitz. If 1… Qa3 then 2. Kb1
1. Bd4 Qd5 2. Qa6
Bf4
I can’t find any clear solution to find a mating sequence…. im sure i can take a peice after a few moves but nothing is coming to me that is substanial..
I’d play Bd4
I cant find any decent continuation..
Bd4 … then id play Qb3
The problem is that Bc8 by black negates everything
1. Be4 Kb8
2. Bc5 dc
3. Qb3
OR
1. … Qd5
2. Qa6 Kb8
3. Ba7 Kc6
4. Qb5
OR
1. … Qg5
2. Qa6 d5
3. Bc5
1. Bd4 (for the control of a3)
a)1. … Nf2
2. Qb3 (double threat on the K and the Q
2. … Qa3+
3. Qa3 Kb8
4. Qb3 and Qf7
b)1. … Qd5
2. Qa6 Kb8
3. Ba7+ and mate in 3
c)1. … Qb4 Exchanging the Q with the R
1. Bd4 e.g. Qd5 2.Qa6 Kb8 3 Ba7 white wins
I would try Bd4 to force Q away from K, then move Qa6 and see what I can do from there. If Kxb8, then a forced mate follows starting with Bxa7.
very good one..
first plan is to get a7 square in control then we can then transfer our queen to key a6 square.
so.
1. Bd4 is good move i think. if Qd5
2. Qa6 with good attack
1. Bd4 with the idea of 2.Qb3 looks like the idea.
Bd4 threatening Qa6
White is two pawns down (even if this isn’t relevant at the very moment but it will soon count ) but has a very active rook. If he was to make his queen participate in the attack he would have very dangerous threats….
But 1.Qa6 ? Kxb8

2….c5 3.Qxa7+ Kc6 4.Qb7 mate
Black could make a tricky attempt by 1….Qg5! 2 Qa6 d5!
Now 3.Bc5? fails on 3…Kxb8 4.Bxa7+ or 4.Qxa7+ because the bishop can’t perform both tasks of trapping the king and delivering the mate
but White can correct his idea with 2.Qb3 d5 3.Bc5 but here also 3…Bc8! sets problems or 3.Bb6+ Kd6 !
so 2.Ne4! Qd5 3.Qa6! wins since it prevents both the d5 and the Bc8 defences but Black still has something !
2….Qf5! so 3.Qb3! (3….Bc8 4.Rxc8+ ) 3….Qf1+ 4.Ka2 Bc8 5.Rxc8+! and White is (finally) a piece up !
Ba5 Qxa5
Qb3 …
Qb7+
1.Bd4 Dd5 2.Da6 and black side need to sacrifice the queen to avoid check mate…
Bd4 should win I believe.
