seeing ghosts when playing chess


Almost all ghosts are tricks of the light or photographic manipulation. A handful cannot be explained...you must see through the fear and judge if the threat is real...

I guess I'd say try to be as explicit as possible about the move. If the initial impression is you're scared or surprised or dismissive of your opponent's move, that's fine, but then find the exact threat. Even bad or stupid moves can make threats... and if there is no threat, that's fine too, but you have to look hard. Spend some energy finding the worst thing that move can do to you.
After you know the worst thing that can happen, base your calculation around that.
And remember moves do a few things at once:
1) All the squares the moved piece attacks
2) All the squares any uncovered piece attacks
3) All the squares the moved piece no longer influences
4) All the squares a pinned or defensive piece no longer influences
If you base your calculation around these things on every move, then it will be hard to miss simple tactics... of course this takes a lot of work, but eventually it becomes easy enough to do in faster games (until then play time controls that are long enough for you to practice good calculation habits).
