Forum:Which player has the priority to respond to a summon?

I mean, the turn player or the opposing player. Although I think that in 95% of times is better to let your player respond to the summon and after you can chain a card that also responds to the summon, so you get the effect, and your opponent may no get his card effect, I have find a situation, (there will be more for sure) in which it would be better if you have the priority to respond to your own summon. So I want to know if I could call for priority to respond to my own summon.
