For the benefit of those that don't have chess sets or chess programs at home, when stuck for what move to make (which in my case is frequently!), in order to visualise the consequences of making moves I think it would be a good idea to have a practice board function on the site where you can move both sets of pieces.
Ok, I confess not being able to picture the scenario more than a couple of moves ahead (i'll probably be inundated with challenges now!). Just think it might help beginners like me to improve their game.
