Threat is related with gaining material while pressure means some kind of positional advantage that forces one of the 2 players to defend or take defensive measures. I will give you a simple example:
What exactly is pressure?

Goddric, thank you for the annotations, and choice of opening as it was clearly illustrated in the game fragment you presented. I've saved the pgn from the source info, so I'll have it to run through and consider your words move by move again. I think you explained it very well - nice to have a muddled concept clarified.
Thanks again!

Yours is the first post that I have read on this website that demonstrates a thorough understanding of the difference between (pressure and threat). The jargon or terminology I use are {(restrain, blockade (overprotection and prophylaxis), execute the enemy. I would go further with your analysis and commentary, but it will not keep the focus on the OP's topic
I heard Nakamura say he felt good over his lost game against Carlsen because he was able to keep the pressure on this time around.
I always thought "making threats" and "pressuring the opponent" were the same thing. But I'm not so sure anymore.
I'm starting to think maybe pressure is more about restricting a piece or pawn's mobility, whereas threat is about the material itself. Is it like this - Pressure restricts the variations your opponent could play and hinders their best plans, but threats means they have to keep an eye over a square or a piece or else they will lose it or control of it??
