Hi chess.com.

You're going to think I'm a total clutz, but would it be possible to have an option for a move confirmation button that pops up in online chess? Something like:

I'm a bit clumsy sometimes, and I think this will be a good little prompt. Obviously optional for the player. 

ED. 

You mean after you've clicked submit move? Two confirmations isn't reeallly necessary. 

What is the purpose of the SUBMIT button then?

Because I'm a clutz, mainly.
