I honestly don ' t play against a Sivir in months , so all I ' ll say is theoretical but Max Q for sure so you can atleast attempt to outpush her , avoid putting traps except for maybe some backline ones on the bushes that may help you if you ' re attempting to escape someone . Make sure her spellshield is down before using your ult , or , if your support has any good CC Thresh , Blitz , Morgana you can even use your ult to bait out her shield to allow for an easier engage for your support Your range is huge , poke her with hits and be careful with positioning , if you position yourself properly , Richochet won ' t hit you a lot Especially in lower elos you can attempt to bait her into mispositioning using traps while she has low mana . Overall not a very good matchup for Caitlyn , especially considering Sivir should outclass her midlate game due to Sivir ' s higher AOE damage and utility for teamfights lategame .
