Is this more of a Dutch Defense or a Semi-Slav Defense?

A nice attack but overlooked a mating sequence. I'm having trouble trying to think what defense this more likely resembles. I treated it like a Dutch Defense but the Semi-Slav also has an f5 line. Any ideas? Rapid time control.

Semi slab to dutch but The Dutch is supposed it's variation to be like this

Slav

I mean The Dutch shouldn't be played like this this was the semi slave then tried to switch to dutch but this variation isn't supposed to be played like this

This is the Dutch, without any doubt.

Thanks guys. f5 shows up in both explorer databases but I have never seen this played before so was a bit confused

It;s obviously just a stonewall defence. There;s no set move order for it.

White plays the opening badly.
