1)X looked like the only team trying out there.
This means he played crunch ? (it was in the cup)
2)Y put more into this game than X.
This means X was playing easy?This was a game with a team from the 7th place so it would make sense.
On the first, yes. The "only team trying out there" is only displayed when it's a crunch vs. TIE. On the second, it means either a TIE vs. Normal or a Normal vs. crunch. If you know the other team is a bot then you can be sure that they played normal, otherwise you can try to figure out their tendencies by looking over past matches.
I don't have time at the moment to answer the other parts, though hopefully someone else can. I'll try to check back in later this morning otherwise.
