It is easy to beat him.
Here, 'It' is used as a Subject placeholder.
To beat him is easy.
My question is in 'It is easy to beat him'....the Infinitive clause ' to beat him' is modifying and describing(giving more information) the predicative Adjective 'easy' ?
Like in this sentence,
He was ready to go to the movies.
Or, it is just an extraposed subject not modifying anything in the sentence?
