when can you move

If your opponent play a move, but does not stop his clock, can you move, or shoud you wait until he does?

Hi eg0210.  The opponent's clock stops automatically once he makes a move.  In case you don't see this happening then it may be some lagging (slowing) in your internet connection.  In the same way, when you make a move you don't do anything to the clock, it automatically stops your time and starts your opponent's.  Cheers.

If you mean OTB (Over The Board), then you can move as soon as yuor opponent lets go of the piece that he's moving.

In non-rated OTB play, it is normally courteous to point it out and have your opponent push his clock. We all forget to do this from time to time.

In rated tournaments, it really depends on how much of a competitive punk you happen to be. 

95% of the players I've played across all rating levels have been nice enough to point it out for me and I've extended the same courtesy to them.

In mutual time-trouble situations or if you're trying to win at all costs, you would deliver an oscar winning "pondering my move" acting performance and flag him  ... though if you choose this plan, you're going to come off as a bit of a jerk :)

Technically you are not allowed to move before you opponent stop his clock.

Practically, point it out to him, he stops it (except if he has a few brain problems), and you move, everyone is happy and you win.

Pretty much what Shivsky said. In OTB tournaments, I'll usually point it out if it's the first time my opponent has made that mistake. If they do it repeatedly, I'm not going to bother pointing it out every time, but I'm also not going to play slower just to abuse their mistake, either.

Half the time, I actually don't notice right away if my opponent forgot to hit the clock. I always hit it out of habit, so I never forget, but I don't necessarily look at the clock right away when my opponent moves, so I might not notice.

Yes, thanx for your answers, that answer some of my question. But what I was moore looking is situatuon in blitz game, when the problem is not forgeting to puncht the clock but the time when you do it.

So if I make concrete situatuon: First player play some move. When can opponent play his:

a) immediately why first player drops the figure

b) when first play push his clock

You may only move when you opponents turn is over.

The turn is over when the clock is pressed. 

I will correct my earlier answer.

Back when I played OTB, you were allowed to move when the opponent's had had left the piece he moved.

Nowadays, the rule is different... you cannot move until the opponent has pressed his clock.

True, you come over as a jerk, but your opponent comes over as a bit of a noob for forgetting to press the clock in the first place. So it kind of a tie.

A slight variation would be to suddenly "notice" and quickly point it out when he has about 2 minutes left, and then flag him down. That way you come across as more honest

Thanks! Who says we can't learn new things in this forums *evil grin.

I hate it when jerks don't tell me what I'm supposed to do.
