The touch-move rule is for the better. The point of the touch-move rule is to avoid people from playing a move and then taking it back and completely switching moves before hitting the clock. It's far more fair than without it. The players know the rules, they should be careful about which pieces they touch. As for the accidentalness- that is completely up to the tournament director's choice, there is no distinct rule. If the TD believes it was an accident, they are likely to not put the touch-move rule in effect. "Nervous tick"s fall on the fault of the player, but as you play in more tournaments, it improves and hopefully the player will learn to stop making those mistakes.
Most directors will follow by this friendly tip:
Without a neutral witness, Rule 10 depends on the reliability of both the claimant and the opponent. If they disagree then the TD should strongly consider denying the claim. In most cases, by denying the claim the TD shuts the door to all false claims. Upholding a false claim usually does more harm to more players than denying an accurate claim.
Whenever I think of the "touch move" rule, I think of that time someone tried to abuse it to disrupt Hikaru while he was winning. This kind of strategy can be used in any IRL tournaments and is way more unfair than for example: adjusting your piece without declaring it first. I think even just accidentally touching one of your pieces (without even leaving the square it was at) and being forced to move it is more unfair to the player that touched said piece.
I know why the touch move rule is a thing, it's to prevent people from testing moves, bluffing and overall to keep the game fair.
But in consequence, a simple nervous tick can ruin your game, even if you didn't do anything that is remotely unfair. Meanwhile the other player can call the arbiter and sometimes purposefully destabilize you and he will face no repercussions.
I think we should be more lenient on this rule. Like only enforcing it whenever there is clear signs of abuse or at the very least, when the piece that was touched moved to a different square.
Anybody else feels that way?
