Here's a question for you guys, since being nice appears to be a sticking point. You've made it deep in a tournament, and your opponent keeps forgetting about his abilities. Maybe his Firespray has Recon Specialist, but he's taking only one focus. Maybe for some absurd reason he isn't using Gunner after Han misses. Do you remind him, or do you let him try to figure it out for himself?
Two answers, depending on context.
1. I'm teaching someone new and they aren't remembering everything right away. I remind them what they can do but leave the choice to them.
2. I'm playing against someone who owns the same game or has played it enough with me to know their stuff. I do not remind them.
My goal is to play my best, win or lose, and to have fun doing it. I have no obligation to remind my opponent things that they are supposed to already know and remember themselves. Sometimes I will make an exception to this.
That is my way of playing.
Back on topic, I think next time thus comes up, the OP might mention that the other player is taking a little longer with his choices. If it persists, ultimately it is your choice for calling a TO over about the matter. If you think it is an issue that won't be resolved otherwise, maybe it is a good choice.
Something different I thought of, if you think the player was just having a difficult time is maybe get together with them to test squads out and help them learn to anticipate where their opponent will maneuver. If you have an idea of that, usually you will know what maneuver you want to make before the planning phase even starts.
