Why I play worse in offline chess but good in online why

any tips??

because otb your facing players who are bad

MY FIDE IS 1700 (300) LOWER THAN MY CHESS.COM

That's about normal. Chess.com ratings are a bit inflated, the best players are 3300+ on chess.com.

There's a few problems that I face:

1. You aren't looking directly over the board in OTB, not to mention there's nothing stopping you from playing a move (other than the consequences of doing it), so your awareness of the board may be inherently stunted.

2. You have to manually pick up and move the pieces (and, obviously, can't premove), which makes time trouble much more of an issue. The touch-move rule doesn't help (assuming you're playing a formal game).

3. The king and queen look way too similar. Maybe it's just me, but I find them easy to confuse.

This. I can't find it right now, but there have been some threads collecting data, and I believe it suggested people's chess.com ratings are, on average, about 200 points higher than their fide ratings. (Lichess ratings, are, in turn, something like 150 points higher still).

Offline games can feel more serious due to the physical presence of your opponent and the competitive atmosphere.

Chess is a visual game. So 3D can be tricky, especially in short time controls. Bishops sometimes look a like pawns with bad sets. Not enough light can be an issue too...

So this is why Magnus is 400 points lower rated in OTB than on chess.com?

ChatGPT fails again.

Why are you lying about your rating , you still have a good classical rating 1572.

Don't lie the fide profile you sent does not have your name nor matches birth year. 1572 rating is not something to embarrassed of

He says "offline" which mean OTB, I think.

Because in OTB chess you need to choose your own moves.
