Early game
Let's start off with early game. During early levels, you are going to struggle with your mana, since you don't have sufficient mana sustain yet. For that purpose, you need to choose whether you want to poke since level one or not. If you are able to farm with autoattacks, always try to poke down your opponent, while if you know, that you are going to get punished for every single cs, try to rather save your abilities to last hit otherwise unreachable minions.

Mid game
After you reach 2 items, you are mostly strong enough to do whatever you want in lane, unless you are facing some counterpick or unless you are incredibly behind compared to your opponent.

If you are behind, try to go for some picks with your Unstoppable Force and if you don't have it, keep farming on your side-lane to scale up. You can even do it generally, if your team does well, but you should always look around the map to use your Unstoppable Force.

Late game
Late game as Malphite is mostly really difficult. Yes, you are strong with your Unstoppable Force, but with great powers, comes great responsibility. In late game, any lost teamfight might mean, that you lose game. For that reason, it's crucial to understand when to engage and when not to engage, it's simply double-edged blade.
