A pleasure to see Vlad again, and nice to see he's not lost his mojo.
10a was my first as well.
I was puzzled about 7d and 14a, my last two in. Couldn't get a real parse on either that worked for me.
Like Brendan, it looked like the first couple of letters in 7d that I needed to justify. Then I read geeker's post. D'oh.
Agreed the general tone about 13a and, to a lesser extent, 17a.
I still can't see what's so clever about 14a though.
