What is the best online c++ tutorial for experienced programmers?

I'm an experienced C# programmer.

I wanna learn C++ but i don't want a tutorial which explains me what a variable is !!!

It's very important that it doesn't teach me 1000 years ago C++ versions. Only C++ 11/14 !

I didn't spent a $ on learning C# and now i'm master in C#. So i want the tutorial to be free.

Thank you.
