e.g in RHP u have to click on the piece and click on the block were u want to move, in Uchess the go with a drag-method where as u click on the piece and drag it toward the block where u want to move, personally ii think its easier to do the drag-method. understand what i mean?
Well the two sites appeal two different styles of play,correspondence and blitz:in correspondence it's more contemplative ,and even after you clicked the piece you think a little more before clicking ''move'',in blitz chess it would be waste of time to click twice because of very short time controls,and you don't even have time to think as much as on Rhp.
However I don't see how these things makes more ''freedom' on a site than on another.
YOU have the freedom to choose what kind of chess and in what site you wish to play.
I could do it. I even experimented with it 3 years ago. But then browser compatibility would have been a real problem. Not so now, but I don't believe it is worth the effort all the same. I can foresee the mass of requests for a 'take back move' option if it was implemented....
Early on when uChess was launched some people wanted a 'move' button to match RHP - so there is no pleasing everyone.
i think it is great as it is atm. i used to play blitz chess but got fed up with my rash moves and was so happy when i found a site where i could sit and analyse moves and see how they looked before i made my move.
i think having one site cater for correspondance play and another to cater for blitz play is the perfect solution to please all of the people all of the time.
