1. Kb2!, and Black don’t have any reply for 2. Nc3+ forking the K and Q. If the K moves, 2. Ndc3 traps the Q. If 2…QxN, 2. the other Nc3+ forks.
1. Kb2! Kc4 2. Ne3+ Kxb5 3. Nd5 Kc6 4. Nc3
winning
Kb2!
1. Kb2 theating with fork,and after any Black king move will be followed by Nd1c3 catching the black queen
Qb2
kb2 kc4 ne3 kb5 nd5 looks decent
e4 followed by Kb2?
1. Kb2! and the Queen loses by all means…
King to B2 ends up winning the Queen and afterward the game I think.
A win ! Kb2
1 Kb2 Kc4
(1 .. axb5 2 Nc3+ and 3 Nxa4)
(1 .. Qxb5 2 Nc3+ and 3 Nxb5)
(1 .. Qxd1 2 Nc3+ and 3 Nxd1)
2 Ne3+
(2 N1c3? Qb3+)
2 .. Kxb5
3 Nd5 Kc6
(3 .. Qd1 4 Nc3+ and 5 Nxd1)
4 Nc3
… and the queen is trapped!
after Kb2 there is a threat to fork black’s king and queen, while moving the black king to avoid the fork doesn’t help because the queen is trapped after N(1)c3
After 1. Kb2, no matter what black does, the Q is lost.
1… Ke5 2. N1c3 9other K moves similarly if no fork is possible)
1… Q:b5 2. Nc3+
1… ab 2. Nc3+
1… Q:d1 2. Nc3+
The first thing that comes to my mind is 1. Kb2! Any capture by Black loses the queen, and other moves run into 2. Ndc3 and the queen has no squares.
