positional tactics

i know this sounds really stupid but is there such thing as puzzle trainer where you find the best positional moves instead of direct tactics. if not how can you improve at this. im 1800 uscf player and looking to take my game to the next level. hopefully you get what im saying

comment

not a bad idea +1

but positional chess you learn from the classics 

but as a trainer that would be nice

There are books with positional/strategy problems:

Good Move Guide by Bent Larsen (chapter Find the Plan)

Can You Be a Positional Chess Genius by Angus Dunnington

Test Your Positional Play by Bellin and Ponzetto

The Ultimate Chess Strategy Book by Alfonso Romero

But a positional chess trainer would be cool.
