Well I have been on the site for over a year. One of the many reasons I canceled my memberships.
Will you let me know what happens when you try to use the computer workouts? I just attempted this and they seem to be working for me. I'm using an Mac laptop with Google Chrome to test.
Try the "most important K vs K+p endgame". The computer does not attempt to queen the pawn. Just gives it up without a fight. I belive this happens in all the drawn positions.
Ignored once more.
