You'll definitely want to consider a few factors before you make your decision:



1. Do they have a duelist champion to oppose your split-push?

2. Is my team in a position to push?

3. Can i push fast enough?

One of the toughest things to learn is split-pushing. It's a skill that is not often practiced because not a lot of champions are capable of performing it adequately compared to their usual teamfighting. Yorick is the exception - he is 90% split-pushing power and 10% teamfighting power. It doesn't mean he can't team fight, but there are so many factors that go into team fighting that will often result in you being a lackluster participant. Most notably, area of effect abilties will often be the source of the killing blow to your pets and maiden of the mist which both dictate your potential to secure kills, deal damage and eliminate threats.But knowing when to split-push is a tough decision because not every game is the same. It mainly comes down to your position in the game, your match-ups, your team mates and your goal.This is arguably the biggest factor. You should never split-push against aor. You will not be able to reliably defeat them in a one vs one and you'll likely just die in the process of attempting it. If you are against one, your best option is to teamfight or look to catch them out as they come to the side lane.This is often the biggest mistake new players make. They constantly run up the side lanes and die while their team is not able to do anything with the pressure. It's important to make sure your team is in a position to actually do something with the pressure you're creating, otherwise your sacrifice is for nothing. Wait until they get in position, and then march forward. If they refuse to get into position, then don't split-push.This will come with experience, but judge based on your own opinion if you can outpush the enemy team. If they have five champions charging to your middle while your four team mates are defending the turret, can you push into their base fast enough that should your team die, you can end? If not, you might want to recall and defend at the base. I'll always recommend pushing anyway because in solo queue people mess up and make mistakes all the times, and five man dives onto four champions under turret never goes smoothly. A push of five champions will often result in two dying, meaning you only have to outpush three.
