Trades

Every position is different and knowing if a trade is good or not depends on many factors, so it takes experience to navigate.

Usually you want to keep your active pieces (pieces developed and doing something) and trade your inactive pieces which aren't doing much. Here is a video of mine from last year where I talk about the positional nuance specific to Bishops, but it definitely relates to what you are asking about.

Knowing what trades are good or not also depends on knowing what endgames are winning for you (from the pieces left on the board after a trade), so I'll include a super important endgame video as well

For me, I trade when I have a following up, generally wins material "by removing the defender"or opening lines for my rooks or diags for my bishops ,

Also i will avoid trading good pieces for bad ones . That may not be very well explained but it depends on the position , generally a centralised Knight for a bishop which is stuck behinds his pawns is a bad trade , trading rooks in a way that gives the file it's a bad trade, trading central pawns when your king is still in the center is a bad trade and so on

Thank you so much for the video.
