The most efficient tool for the realization is the dynamics of flight d5.
It prevents various possibilities of cooks and duals, allowing exactly the thematic variations.
And that flight is even provided by a different play and mate in the set play.
Halfbattery Rd1,Sd2,Pd3 looks as a simple but also a very powerful tool which must be handled carefully to avoid duals.
