What CTS as to offer is over 20.000 chess problems for us to solve and comment on them, every service provided by the server is free of any charge the server is quite fast and stable, and they answer support emails quite fast for a completely free service.

The downside of this website in my opinion is the poor graphical interface presented to us, and the little time given to solve the problems, although it is more time then some other tactics websites it still is very short for me.
