Considerably easier that the previous problem.
We don’t want the Black king to be safe by escaping to c8, so the White queen, ready as always to sacrifice herself for her King, lures the Black king out with
1. Qa6+.
1. Qa6+ [“I’m always the one to set a good example. All in a day’s work.”]
1. … Kxa6
2. Nac5+ [“There’s no road back for you, buddy.” The knights have been emboldened by our queen, and one of them lays down his life as well.]
2. … Bxc5
3. Nxc5+ [“Ready to take over.” Our boys have learned well.]
3. … Ka5
4. Ra3+ Kb4 “My kingdom for a horse.”
“Well, that’s unavailing anyway”. [4. … Na4 5. Rxa4+ Kb6 6. Ra6#]
5. Nd3# “Good job, son.”
The first few moves are obvious: 1.Qa6+ Kxa6 2.Nac5+ Bxc5 3.Nxc5+ Ka5. Now White has to find 4.b4+!, when Black is mated after 4…Kxb4 5.Rb3+ Ka5 6.Bd2#.
looks, that something like
1. Qa6+ Kxa6
2. Nac5+ Bxc5
3. Nxc5+ Ka5
4. Ra3+ Kb4
5. Bd2# would be the correct plan.

We have two knights against c5, and we don’t want the king to escape via c8.
This opts us to test a queen sack, pulling king into a-file:
1. Qa6+ Kxa6
2. Nac5+! Bxc5
3. Nxc5+ Ka5
4. Ra3+ Kb4
5. Na6#/Nd3#
all black moves enforced, therefore relativly easy to find the mate in 5.
But a pitfall existed, important to start with the right knigt. Here is the line that doesn’t work:
1. Qa6+ Kxa6
2. Nbc5+?? Ka5!!
simply delaying to take with bishop, now knight stands in the way for checking with rook, as does rook stand in the way for checking with bishop. This looses, I’m afraid. Depending of what white does now, black has a flexible reply.
1. Qa6+ Kxa6 2. N(A4)c5+ Bxc5 3. Nxc5+ Ka5 4. Ra3+ Kb4 5. Na6+ mate
Qa6+
how about this?
1) Qa6+; Kh6
2) N(a)c5+; Bc5
3) Nc5+; Ka5
4) b4+; Kb4
5) Rb3+; Ka5
6) Bd2++ mate

Forced mate in 6 after Qa6+, giving check at each move.
Hi Susan Polgar,
White wins the game.
1.Qa6+ K*Qa6
2.Na4c5+ B*Nc5
3.N*Bc5+ Ka5
4.Ra3+ Kb4
5.Nd3++ Mate

To Jan:
Almost correct plan, but the last move is not:
5. Bd2+?? Kxc5 white looses.
Better is to move the knight from c5 with check, and there is no escape field on c5, so it mates 🙂
Sacrifice very nice.
This is called “enticement” if I’m not mistaken.
