Callouts, plant sites, angles, all these are key to success, and that's not even taking into account the specific aspects that make each map different - with Riot making efforts to create maps that have unique gameplay features like Bind's teleporters.
Split Map: Spike locations, and callouts
Split Map Strategies
Split is in some ways a traditional three-lane map. Two Spike sites sit either at opposite ends of the defending sides part of the map.
A is arguably the hardest bombsite to attack in this map as there are two entrances for the defending team to set up from, this gives them greater unpredictability and makes it harder for attackers as they need to cover two sight lanes when pushing in.
