Hi @jaki01! With white pieces I would play 1. Ng5!, black has 2 options (Nxg5 or cxg5), so.. if 1... Nxg5 2. Rg7+, if 2... Kh8 (the worst move) 3. Kg6+ (with the rook) 3... Nh7 and 4. Rxh7#, so, if black plays 2... Kc8 3. Rg6! (Threatening checkmate in h8, so Black only has one move): 3... Nh7, so, with this I just have to check 4. Rc7+ Rg8 5. Rg7+ Rc8 and it's a draw :)
