What purpose does は serve after へ in this sentence?


> ところで、今週末のゴルフ大会 **へは** 行くんですか。

I feel I have a decent understanding of both of those particles, but I'm
wondering how the meaning of the sentence changes with and without the は after
へ.




は is the topic particle and can be used in combination with a variety of
particles. When combined with the subject particle が or the object particle を,
は usually _replaces_ が or を. With all other particles, it _goes after_ the
particle. (In fact, を＋は may also turn into をば, see Dono's comment.) In your
example sentence, it makes ゴルフ大会へ "to the golf tournament" the topic of the
sentence.

A similar sentence would be

> 今週末のゴルフ大会には行くんですか。

and the difference between this and your sentence is just the difference
between に and へ.
