notation before moves

I played in a tournament and a player kept writing his moves before he moved them - sometimes he actually changed his mind what he was about to play and erased it on the notation sheet and wrote something new

Fide rules clearly states that you are not allowed to write your moves on the sheet before you have played your move.

However there is no real penalty for writing the moves before you move.

I think if someone writes his moves in advance he should be forced to play the move he wrote like when someone touces a piece on the board.

I think it is very annoying to see someone write his moves in advance because you might start planning on what you would do.

The tournament director saw it but did nothing.

You should have complained to the arbiter, did you ?  Sometimes, they will take no action unless one of the players complains.......

Yeah, often TDs can see one player committing an infraction (lets say playing after their time has expired) but it really is up to the opponent to, such as in the clock case, to call the flag to win.

I like it when they lay their pencil/pen across their intended move as if I care and may try to look lol.  First of all, I don't need their crappy moves to help me analyze.  If it's a good move I'll have looked at it, if it's a bad move I don't need to worry (this is my mindset during a tournament anyway).  If I really tried to notice it would just be distraction.

The same when players overtly stare at an area of the board, I just sort of chuckle to myself for half a second and ignore them.

Anyway I never complain about this (you can, that's just my decision).  If that's their habit after many years of playing I just let them do it.  To me it would bias my analysis, waste time, and distract me... maybe that's part of the reason why I don't care :).  I've seen score sheets of guys who do this in pen and simply cross out moves and their sheet is really messy at the end, this almost makes me chuckle hehe.
