Predicting and countermoves

I'm finding out that it's getting easier to win at chess than lose but perhaps I've gotten better at predicting the computer's movements with my countermoves which shows improvement?

I delivered another checkmate to the king, but I felt a little too confident tonight with the game which could prove fatal if you think you're winning but I still am but that hasn't always been this easy, and I wonder if I should play a different level but that might take too long then?
