I spotted the main idea of this one pretty quickly, but had seen similar kinds of themes in the past.
8/K7/7P/3r3k/3p4/5pPp/8/1R4B1 w - - 0 1
While I was putting chess pieces on my board I saw the first move. But I had to struggle with V-2 a little. The puzzle is instructive and the idea is easy to remember.I haven't seen the idea earlier. I spent about 15 minutes on V-2.
1.Rb5! Kxh62.Rxd5 f23.Bxf2 h24.Rd8 Kg55.Rh8 h1=Q6.Rxh1It's a win for white.
1.Rb5 Rxb52.h7 Ra5+3.Kb7 Rb5+4.Kc7 Rc5+5.Kd7 Rd5+6.Ke7 Re5+7.Kf7 Rf5+8.Kg7 Rg5+9.Kf6 Rg6+10.Kf5 Rg5+11.Ke4 Kg612.h8=Q h213.Qxh2 d314.Kxd3 Rd5+15.Ke4 Rh516.Qf2 Rh117.Kxf3 Rh5It's a win for white.
You should also look into 10........Rh6 guarding the h8 square.
10.Kf5 Rh6?11.g4+ Kh412.Bf2#
Shorter, yes, but that mate is what makes the position won for white in all the longer lines.
For me, this is Rambo Attack Tactic [ 1) R5e8+!! Kh7 2) Qxd2! R8xd2 3) Rexa8 ~ Black resigned 1-0 ]
