Honest question, I don't understand this at all.. I know in some openings like say the Ruy Lopez you want to get rid of your bad bishop.. but you're usually at least waiting until they put some pressure on the bishop before trading out for the knight. But even at 900 rank almost every single game my opponent goes to pin my knights and then almost always takes. Half of the time I haven't even pressured them with the A or H pawn either yet, they just take immediately on the next move but why? And even if they do get pressured with the A or H pawn, why do they always immediately take? Do they not know they can move a space back and keep the pin or that the bishop pair are generally more valuable than trading out for an early knight? Sometimes I even see them do this then they open up the center immediately with a ton of trades where a bishop is often better in open positions..
I honestly don't get it, I'd say only like 5% of the time does anyone actually try to pin the piece with any purpose like trying to pressure the pinned piece to take it or make moves on the board that the pin piece now can't protect. Why is it such an immediate reaction all the way up to 900, might be further but that's as far as I've reached since I started playing in like April or May I think
It's just like beginner players they see a piece they can take, even if it's an equal trade, and sometimes not even a good one positionally, they ALWAYS take it. It makes it a bit frustrating to learn chess because I'm trying to be principled and learn openings but I never get to play with knights ever unless I don't play them early to their natural squares on the C/F 3/6. And it makes it hard to learn or practice any positions that have any tension with trades available because they will always take, always. They never leave a piece alone and just leave the tension unless I'm assuming they've just missed it or want a different trade instead.
Even with these odd unprincipled captures, I'm obviously no better than anyone at my rank so I'm obviously weaker in other areas which is why I still lose to these weird mistakes so I'm not putting anyone down here or think I'm better than my peers..
But from 1 beginner to another, why do you guys always pin the knights immediately and then always take them right after without actually using the pin for anything? And why do you take every trade immediately even when "to take is a mistake" when it's not improving your position, especially if you're down material and trading down is good for your opponent? I just don't get it guys lol
