I only play to win tournaments. Whatever the rating I have does not matter, but I prefer winning tournaments with larger prize pots, and thus stronger players.
So I don't care about ratings; I only care about how much I improve. If I disconnect and lose rating because of that, it's no big deal, and I don't care if I let myself lose on time in blitz games to think more cohesively of my move choices. I also only play against higher rated players.
I do not play against computers because they do not play like humans, and if you want to beat humans, you have to practice against humans. Unlike computers, humans develop plans and can sometimes make better moves than computers with long-term positional principles. This allows you to learn good moves from computers as well as humans. Also, humans make tactical mistakes, allowing you to practice swindling in theoretically lost positions.
I also have a uscf floor of 2000. I earned the NM title in the US and since coming to Portugal have earned it here as well....... those two titles and 50 cents ( euro cents) will get me a cup of coffee !
