Logical problem:
Main Plan: 1.Ra2+ Rxe1 2.b4+? but 2…Rxb4!
The bR has to be diverted away.
Solution: 1.Bh4! Rf6 2.Ra2 (3.b4#) R1f4 3.Be1+
(switchback) d2 4.Rxd2 (switchback) Rf1 (switchback)
and back to the initial position but with the bR on f6.
Then the main plan follows: 5.Ra2+ Rxe1 6.b4#
Unthematic variations: 4…exd2 5.Bxd2+ Rb4 6.Bxb4# 4...Rb4
5.Rd4 any 6.Bxb4# and 4...Rc4 5.R~+ Rb4/Rc3 6.Bxb4/Bxc3#
The problem is after:
Logical Problem:
Main Plan: 1.Bf2+ Bxb5 2.g4+? but 2…Rxg4!
The bR has to be diverted away.
Solution: 1.Rb1! Rh2 2.Bf2 (3.g4#) Bc8 3.Rb5+
(switchback) c5 4.Bxc5 (switchback) Ba6 (switchback)and back to the initial position but with the bR on h2.
Then the main plan follows: 5.Bf2+ Bf5 6.g4#
