To the OP, if you accidently touch a piece you don't have to move it. Read the laws of chess again.
Wrong regarding OTB.
Amazing people post false and misleading information. If a piece is touched (accidentally or not) it must be moved if a legal move can be made when playing OTB.
Think players can claim ... “ oh - it was an accident” and be permitted to move another piece ?
Not so.
