intuitively
If we don't change our choices, it turns out that we initially guess only one box out of three, because the presenter opens his box after we have chosen it.
If we always change our choice, it's equivalent to choosing one box that won't open, but the other two will definitely open - hence the statistical advantage - we win in two out of three cases.

Two will still be opened 1,2 or 2,3 - the first will be opened to check if there is a prize.
no. Choosing one box that you definitely can't open is like choosing two boxes that you can open.
And if you choose one box to open (we can only open one ourselves), then the master will still open the empty one.
