You may be expecting to use an HM (Hidden Machine) to teach one of your pocket monsters Strength in Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee!, but, as with Pokémon Sun and Pokémon Moon, these have been removed. Secret Techniques are their replacement – special skills that your partner Pokémon can use outside of battle.
These Secret Techniques work in the same way as the moves that Hidden Machines had taught – like Cut, Surf, Fly and Strength – but won’t be available to you straight away once you start your adventure. Those wanting to learn Strong Push to move large objects to open new paths will need to progress in the main storyline to the point where you arrive in Fuchsia City.
If you head south of the town, you will bump into the troublesome Team Rocket. You must take the Gold Teeth that they give you to the Warden (whose house is southeast from Fuschia City’s Pokémon Center) and he will teach your partner Pokémon the Secret Technique, Strong Push.
It’s worth pointing out that to learn these Secret Techniques you do not need to lose a move slot, as they cannot be used in battle.
Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee! are now available exclusively for Nintendo Switch worldwide.
