How do you train with tactics trainer ?

Hi !

It may seems a useless question, but it is in fact really pertinent.

I want to know what path are you (mostly adressed to people with high tactics skills) using to train your tactics with tactics trainer.

Do you:

-Play the first one/two moves by instinct/logic and then see the tactics involved ?

-Play move by move the ones you think are the best without trying to find a combination ?

-Visualize untill you see the complete combination THEN move ?

-Other ?

I'm personnaly tempted to do the first two ones and generally complete puzzles with a grade of over 80-90% but it doesn' t seem to help improve.

I think it would be more logical to do the third one but it seems way slower than the two firsts. Would it be better to do tactics without the timer?

How do you personnaly train?

It's what you do or you ask me what the heck is that supposed to mean?
