Grammar

Hi, guys, I wondered if you could help me figure out a few questions related to third conditional tense , which seems to be bothersome and impenetrable for me. Thanks,

My first question is does the sentence " if the ref had the balls, he would have sent him off" have the same meaning as " if the ref had had balls, he would have sent him off"？ Or do both sentences make sense to you?

My second question is: is it okay to write if the team had had an oustanding goalkeeper, it would have or could have won that game?

And I just found two sentences which are related to conditional , and I'd like to know if the sentences are correct or not.

The first one is:" we might have had a good time if we had gone to the party."

The second one is: "I might have called a taxi if I knew it was raining." I was thinking about changing it to I might have called a taxi if I had known it was raining. Which one is correct or do they have the same meaning?

Best Regards.
