You are right mate, it was over in 4 rounds, and so if you got the over 3.5, still good bet and congrats to you. I skipped the fight and didn't bet though, I just waiting for it to happen and see if Inoue will really go up in weight in his next fight.
Kim wanted the action and so Inoue give it to him a solid right hand and Kim went down and was not able to get up.
Just got a feeling mate that the fight would end in 4-6 rounds and luckily it did hehe. Got this one with an odds of 2.96
. With the fight over i hope we can now see Inoue fighting opponents that have more resistance to him, i mean that the fight itself is competitive and not know who gonna win.

+1, great pick and that's what also Inoue said after that fight, that in the beginning, he was feeling Kim because he was just a replacement fighter and they don't have enough time to study him.
So that's what the did, study and read him during the fight itself and that's how good Inoue is.
And again, with this win, he should be fighting in the US next.
