It depends on the way you play the higher rated computers. If you play odd moves that doesn't mean you are playing at that level. It just means you "picked a lock". The computer is an opponent set at a certain level. It would be like in sports where a team faces their opponent and is not prepared in the first quarter, but into the second quarter they learn their opponent's strategy and counter it. The computer is less likely to counter (if it is exactly what I am saying then you will see no deviation).
Look at the Nelson bot for example. It brings out the queen to h4. So, you know that is a target. But do players at Nelson's level do the same? Humans are going to mix it up, and they might even make a move without realizing it is good.
What I would do is play out specific lines that GMs play against the computer. I am talking 1-10 moves deep. Then, play from there. See if you can beat them from some established realistic position.
If you start out with an awkward sequence, then the computer is less likely to reply with the better moves.
i have a 1500 rating in rapid, but i beat a 2000 rated computer and i am rated 2000+ in puzzles,is this typical or am i just bad when it comes to playing real players?
