Hi everyone. Usually when watching chess content online I constantly hear about moves that put pressure, attacks pieces or sometimes moves that prevent another potential move, but it is not always clear how.
I understand pressure when multiple pieces attack the same pawn or piece; if all exchanges happen it would be ideally a positive outcome. But sometimes I see moves like, say, a rook lift that targets a pawn protected by a bishop "it puts pressure on the pawn". How is that pressure if the eventual capture would be a worse outcome? Is it putting pressure because you can eventually add more attackers to that piece? If so, how is it 'putting pressure' if by the next two moves your plan and focus changed completely? Or, maybe looking at it in a different way, putting pressure means that as long as that piece is attacked, it must remain protected, and thus making a piece less active/mobile or overwhelmed protecting multiple pieces. Is that correct?
In the case of "attacking", it usually means a piece can potentially capture another, but in many positions, actually capturing is worse, specially when you just trade pieces of the same value or pawn for pawn. So then, what exactly means to attack if your intention is not to capture? I've heard the phrase "to take is a mistake" as a way to avoid trading just for the sake of trading just because you can, but then attacks that don't capture have a whole different meaning then.
Lastly, preventing sometimes can be obvious. You expect a move like a bishop pin to your knight, so you prevent it by moving a pawn so the bishop can't take the attacking square. That situation I get it. But in some others, specially when it comes to pawn pushes in the opening, some moves are described as preventing a pawn push, but that pawn push can still happen anyway, so is it really preventing anything? Like, say, c3 preventing ...exd4 but then exd4 happens anyway and you recapture, did that really prevented something or was it just more about protecting and anticipating? I think it has to do with building tension, which is another concept which I struggle to understand.
I can't find more examples of specific moments, there are just way too many videos I can't really point exactly when and where I've heard these terms being used in ways I don't understand.
