When I play on-line chess with my friends we simultaneously speak via

Skype. It's much better than ordinary chat. May be in Profile advisable

to note Skype Account ? What do you think ?

Interesting idea. I took chess lessons from a strong FIDE Indian player via Skype, with a 10-1/2 hour time difference. Worked REALLY well. Almost no lag, voice was very clear. This was done using ICC. Unfortunately, I don't know how to use chess.com to do analysis well via the Internet - not sure if it's really possible/practical.

Yes I think this is a good idea too.  There are certainly no technical reasons why this can't be easily achieved as the software and hardware is already in existance.  Take a look at ventrilo and teamspeak, both perfectly capable of voice comminication without lagg from anywhere to anywhere, as is skype.

I would certainly be interested in this.

So, after your feedbacks, I think that speaking option is desirable in on-line chess . Also can be useful training mode .

Thanks.
