is it illegal to slide a piece to its destination during a tournament?


It's not illegal, but it could be disadvantageous to you, since if the piece lands on an unintended (but legal) square, you will be required to leave it on that square.
I'm wondering if, in the case of a multi-square slide, your opponent could make the claim that, since you have released the piece, it should by rule be placed on the first square it slid to.

If it is legal, are you then allowed to slide it back and forth on the board, so long as you don't release it?

I have great Hand-Eye coordination so I've developed a habit of sliding my bishops and rooks in open and semi-open positions (with pretty good accuracy actually). Many players at my club have their own unique way to move their chessmen as well. I'm wondering if that would be illegal in a tournament though. I've only been to one and nobody called me on it but one guy game me a weird look. To me its just kinda fun but is it illegal? I'd hate to have to forfeit a game for sliding my bishop between two pawns or something.
And what does sliding your pieces have to do with hand-eye coordination?

Just don't start a fire!

he means pushing the piece and letting it go
I think that whatever square it's on when he let's go is where, by rule, it would be required to be placed.

And that requires better hand-eye coordination than picking up the piece, putting it on the appropriate square and letting it go?

Most of the rules of official OTB chess are not rigorously enforced in the first place, just to let you know (except the cell phone rule - always turn off cell phones). But you can get away with accidentally touching pieces and other slightly inaccurate things.


If I remember correctly from all the chess videos I've watched of the pros playing (Carlsen, Nakamura etc...), they almost all slide the piece instead of picking it up.

This scenario sounds pretty ridiculous to me. I question whether it's even true, but I'll give you the benefit of the doubt.
Anyway, from the TD's perspective, it comes down to intent. If it's clear that you intended to play Bf5, then any reasonable TD (and any reasonable opponent) would let you play Bf5, even if the piece was touching a different square when you released it. Similarly, if you clearly intend to move your knight but your hand happens to brush a pawn first, nobody will call touch-move to make you move the pawn.
However, if you did this kind of sliding in a tournament game, your opponent could ask you to stop. If you persisted, then the TD would most likely make you stop. This falls under the USCF rule that prohibits "distracting or annoying your opponent in any manner whatsoever",

During USCF games, me and opponents are typically very friendly. I'll typically allow my opponents to take back a touch that was on the edge of accidental / impulsive. I've laughed with my opponents during the game about the current position or some other game close by. This is up to the level of U2100 btw. Just don't bring a cell phone, make loud noises, etc., nothing really distracting.
