Tell?

[chaos]

Yes it is a problem.

You should not be picking your cards off the table. Players on either side of you may get a peak at your cards.

The fact that your cards are in numerical order will not give away much if you do it every hand. If you are going to rearrange your cards, you will need to do it even for hands you are going to fold preflop. Otherwise it is a big tell.

It would be better to just memorize your hand without rearranging the cards. Then do not look back at your cards during the hand. Someone who keeps checking their cards is letting everyone else at the table know that they are not a very experienced player and possibly what cards they hold.
