Is this an illegal move !?

So... two people are playing blitz game 3/2mins time control.

Both of them have around 5-10 seconds time left.

One of them thinks thinks thinks, then suddenly looks at his time 2 seconds remaining so he moves a piece quickly (one second remaining) and so he doesn't loose on time with another hand presses the clock .

Is this illegal, he used both hands?

Yes

FIDE rule 6.2.3  "A player must press his clock with the same hand with which he made his move"

FIDE rule 6.2.3  "A player must press his clock with the same hand with which he made his move"

If the move was a capture with 2 hands it is an illegal move as in article 7.7.1

otherwise see lagomorph indication of 6.2.3

Also promoting 2 handed is counted as an illegal move. 7.5.2

Illegal...illegal move...so.........    Over the board, things can be taken care of in, usually, their own sweet time.  But in this case, under the conditions where the World is soon to be destroyed in, literally, just a few seconds, what's the penalty and how is this handled?   

He/she probably meant 'move' to be the action of the other player, not the chess moves defined in the FIDE handbook (a pawn moves forward one square etc) or precisely, the act of using one hand to move a piece and using the other hand to press the clock.

In casual games though, I do not exactly bother about it. I always allow my regular over-the-board opponent to perform castling with both hands.

No one answered my question yet ! Only reading some FIDE rules from the book.

So what is it ? He moved a pieces in a panic that he's time is almost up , so he used different hand to do so. Does other player allowed to pause the clock and call the arbiter?

So to answer my question?

Amy penalty applies to that guy or... ? If he didn't press the click with another hand he probably would of lost on time , so... ?

YES it's illegal!  Who are these people saying no?  As a former USCF Tournament Director (the FIDE rule is the same) I have issued warnings to unrated players who used two hands,, though I didn't disqualify them because they had plenty of time when the infraction occurred. You must punch the clock with the same hand that moves the piece.

USCF Rule 16 C1: Using the clock. Each Player must operate the clock with the same hand that moves the pieces.

So the player could stop the clock, call an arbiter and claim the win right?

There are 2 kinds of illegal.

1. Illegal behaviour.

2. Illegal move.

The arbiter's punishment for illegal behaviour is discretionary and the standard punishment for illegal move is game loss.

Finally, an answer from an expert.  Thank you.  Still, though, "discretionary" is as clear as mud regarding a definitive answer.  And, illegal moves oftentimes are due to ignorance from novices, so are there less draconian measures like calling-out-and-doing-over?  This latter point is probably more appropriate for slow, over-the-board play rather than blitz. 

no it is not but it is in offense of the other player and offending him/her and it is illegalistof the person who did it.

I know that it is illegal but it is not an illegal move for me because an illegal move for me is like you moved your knight like a bishop or a king like the knight or you move your pawn from the fourth rank to the sixth rank.

Using both hands when castling or moving a piece with the right hand, for example, and you used the left hand to press the clock is illegal.

That is illegal behavior, not move.

ESP-918, are you asking if it is an illegal behavior or an illegal move?

I'm more interested in consequences.

Can another guy allowed to stop the clock and claim a win?

I think you can stop the clock, but i don't think you get the win. You get some extra time on the clock i think. Like Nakamura when Caruana made an illegal move (promoting without placing the queen) See here: https://www.youtube.com/watch?v=BSzGLLTObjY
