Here is the analysis from your move "Rc6" in which Tiger 14 wins with Black!
The time control used was 40 moves/90 minutes
I think that many here are using a too fast of a time control for the very
complex positions which demand more accuracy than you get from fast control!
I believe that it was Mark Young who got a draw with "Rc4" using Fritz7!
