White to move. How should White proceed?
qr2rb2/Q6p/3p2p1/1kp4n/2Nn1B2/Pp6/1P3PPP/2R1R1K1 w – – 0 1
1. a4+ (if 1. … Kb4 2.Bd2#) Kc6
2. Na5+ Kd5
3. Rxc5!+ dxc5
4. Qd7+ Bd6
5. Qxd6#
This is one where I found all the right moves but still didn’t see the mate at the start (I’m a senior citizen – things aren’t as clear as they used to be). I think if you play aggressively in these kinds of positions against vulnerable Kings, you’ll find the right moves 90% of the time.
a4+ Kc3 (or Kb4 Bd2 mate)
Na5+ Kd5
Rxc4+ dxc
Qd7+ Bd6
Qxd6 mate
1. Qd7+ Kb4 2.Bd2#
After 1 Qd7+ Qc6, Black has blocked all of White’s threats.
The winning line is to drive Black’s King away from the protection of the Rook and Queen.
1 a4+ Kc6
If 1…Kb4, 2 Bd2 is mate.
2 Na5+ Kd5
Black’s King seems secure, protected by pawns and Knight, but White is about to breach security.
3 Rxc5+!
White can also mate with 3 Qf7+, but it will take a lot longer.
3 … dxc5
Now with the pawn on d6 gone, the Queen can finally get into the game with a worthwhile check.
4 Qd7+ Bd6
5 Qxd6#
4
a4+ Kc6
Na5+ Kd5+
Rxc5+ dxc5
Qd7+ Bd6
Qxd6++
I wouldn’t say its one decisvie tactic to solves this problem.. Its a series of logical moves that cut off his escape squares..The title to this problem is misleading because it suggests one decisive blow that wins the game..As far as I’m concerned every move is of equal importance..
1. a4+ Kc6 (Kb4 2. Bd2) 2. Na5+ Kd5 3. Rc5:+ dc5: 4. Qd7
a4+

a4+! then, at some point, i think you have to sac the rook on c5.
1.a4+ Kc6 2.Na5+ Kd5 3.Rxc5+ dxc5 4.Qd7+ and win

1. Qd7+ Kb4 2.Bd2#
The King cannot come to b4 and did not have to move anyway.
a4+ Kc6
Na5+ Kd5
Qf7+ Re6 (Ne6? R(c1) d1++
RxR NxR
Rd1+ Ke4

How about 1. a4+ Kc6 (Kb4 2. Bd2#) 2. Na5+ Kd5 3. Rxc5+ dxc5 4. Qd7+ Bd6 5. Qxd6#
Sort of like Murrel for me- logical moves that seemed straightforward, but not that I could see the ending until white’s 3rd move.
1. a4
The only other reasonable starting check was Qd7, but after Qc6, I really could see no viable continuation afterwards- moves like 2.a4 simply let the black king hide at a6 and white is then down a piece with no compensation. Continuing:
1. …..Kc6 (Kb4 2.Bd2#)
2. Na5
Again, the only reasonable looking move. Continuing:
2. …..Kd5 (only square)
3. Rc5
The key juncture. Really only two choices here- Qf7 and Rc5. On 3.Qf6 black must block with the rook, not the knight (2. …Ne6 3.Rcd1#); I am not sure, but 3.Qf7 might well be a win/mate for white, too- I can almost see it in my head, but I can see the line from 3.Rc5 much more easily:
3. …..dc5 (only move)
4. Qd7 Bd6 (only move)
5. Qd6
1.a4 Kc6 (…Kb4 2.Bd2#)
2.Na5+ Kd5
3.Rxc5+ dxc5
4.Qd7+ Bd6
5.Qxd6#
1.a4+ Kc6
2.Na5+ Kd5
3.Qf7+ Re6
4.Rxe6 Nhxf4
5.Re5#
