Hi both
I started really well, but then slowed down, finally nearly finishing. Like you I didn't know 13ac, but the two I'm stuck on are 11ac and 7d.
11ac Seeing double, mistakenly means to invest (5,7). I have S?E?E/?N???E? Is one of my crossers wrong?
7d Attack incomplete, much seen in score (5)
I have A?S??
Only hints please
