Diep doesn't play in #8 the move Bh5 but it does see that Bxf3 loses and plans another move which develops and looks quite good to me too. #5 is a depth dependant trick. A prog to solve it needs to see: Rxe6 Qxe6 Re1 Qd6 Bf4 f5 Qh3 Qxf4 Qxh7+ Kf6 Bxd5 Ne8 Nd5 something mate in qsearch or losing big material. So it's 13 ply normally spoken or 12 ply if you have mating extensions turned on. It *should* be hell of a lot less ply if you have singular extensions because the first so many moves are completely forced.
