Tango is only developed with Human Games, GM games such as Karpov, Kasparov, Carlsen, Caruana, Polkar, Shirov, Kramnik, Nakamura and 100 more GM and some International masters.

With Tango I am experimenting different things, for example in the middle game I prepare to Tango to make 2 0r 3 unexpected moves, thats is to say, move that will make my opponent his book stop working. I could check with diverse books and all of them stop working when they tune their books using only one move or just write 100% , of course I don't know whether a CTG version is the same. but this is a nice challenge for me.

This version moves
E4 50%
D4 50%
