I had it 48-47 Valentina but like you said could have easily been 48-47 the other way or a draw.I had it 48-47 Nunes but thought it could have been 48-47 Schevchenko, or even a draw.
In a fight like that with so many indecisive rounds, you can't really complain about a judges decision either way. I love Valentina but you can't throw your hands up and act surprised when you lose a razor close fight. Take it out of the judges' hands and get the finish or win the rounds so emphatically that they can't possibly give it to your opponent.
