I am going with ko for alvarez around the 10th round, his defence is pretty strong and he likes the opponent to come to him and start throwing, which I think golovkin will do.. Alvarez hits very well I think and without trying to make the brilliant 155 weight class :S I think he will have a bit more power and it will show later on in the fight, it was only khan he was fighting but in that fight I think he did a great job setting him up for the ko with the body shots.. I think a similar thing will happen here . Golovkin is pretty smart though, he didnt get into a war with dangerous lemiux when people thought he would, I think after a while he will really go for it and he could well win,it is going to pretty interesting to watch.. I am sticking with a canelo win though.
