Hello all

its been sometime now and i am slowly getting back into chess.
i would like to know if someone has produced a video on intermediate to
advanced chess tactics/strategy.
all of the videos i have seen are about specific openings etc and games.
i would like more of a general discussion on files, position, tactics,
strategy, etc using diagrams and innovative teaching methods.
i have some books that are good on position and exercises etc but i would
like to see this in video instead.
If you know of any video that discusses general tactics and strategy, pls.
suggest it.

Thanks in advance.
