How quickly can you find the shortest mate in this position? I found the first move eay, but it was harder after that.
Q7/1K6/R7/8/4P3/8/6pp/7k w - - 0 1
V-11.e5 Kg12.Qa7+ Kf13.Ra2 g1=Q4.Qa6+ Ke15.Qe2#
V-21.e5 Kg12.Qa7+ Kh13.Qe3 g1=Q4.Qf3+ Qg25.Ra1#
V-31.e5 g1=Q2.Kc7+ Qg23.Ra1#
V-41.e5 Kg12.Qa7+ Kh13.Qe3 g1=N4.Rg6 any move5.Qf3#
I think it isn't the shortest mate. I will think further.
At last I guessed how to mate in 3.
V-11.Qf8 g1=Q2.Qf3+ Qg23.Ra1#
V-21.Qf8 g1=N2.Rg6! Ne23.Qf3#
For me, this is Rambo Attack Tactic [ 1) R5e8+!! Kh7 2) Qxd2! R8xd2 3) Rexa8 ~ Black resigned 1-0 ]
