I'm curious as to how tactical voting in a 2-horse race works?
<strong>As I said, voting out (when you want in) in the hopes of triggering a referendum.</strong>
This would only work if you were a Scottish Nat living in England, so that you helped England vote out while Scotland voted in, thereby supposedly triggering another Scottish independence referendum (it is not agreed that this would happen in the event of Brexit btw, it's just what the SNP claim should happen).
A non-Nat pro-EU person living in Scotland might wish to vote tactically to leave the EU to reduce the effect of the remain vote in Scotland and give the SNP less of a grievance case if Brexit won. Or, which would be amusing, result in Scotland voting to leave the EU when the UK overall voted to remain. This would be my ideal result 
Anyway, it does get on my nerves, this constant reference to Scotland or England voting to leave or remain. Every voter in the UK is voting whether the UK should leave or remain, nobody gets to decide what Scotland, England, Wales or NI do individually.
