I think this deserves a bump because I'm curious about this as well. Are you still using this method to train?
Playing the computer also seems to be a good way to learn openings to find out why your move, which will inevitably deviate from book, loses.
The only potential problem I have with doing this is the psychological impact of playing something that makes perfect moves and doesn't give you the chance to practice tactics of any sort (unless you switch sides and give it a losing position, of course).
There's a feature on computer chess that I hadn't really thought about until recently. It's "switch sides".
I'd always just dismissed it as a beginner's tool and for those who just can't face losing. Because it's cheating, isn't it?
Well...... yes ..... and no.
I've found that it's actually a great way to learn. I put the computer on the 2000 level - way above my competence - and start a game. When I get into trouble (which I do, embarrasingly quickly) and can't think of a way out, I switch sides. the computer then finds the move I missed, and slowly starts to fight back. I do this two or three times during the game, but only when I can't think of a defence. Invariably I smack myself on the forehead (why didn't I think of that?) when the computer comes up with the right answer.
I tend to play "positional" chess and am comfortable with slow, plodding Queen pawn openings. I need to be more aggressive with play and I think that I am learning this from switching sides with the computer. At the 2000 level it's like being blasted with a garden hose because one wrong move and you're toast.
Try it. You'll find that the computer never quits. Even when you think you have it trapped, it will come up with a move that you never thought of. By switching sides, you may be technically "cheating", but you're also learning!
