I have uploaded two recent games, the first against a human on KGS and the second against a (weaker) program on Tygem. I know the human made many wasted moves defending his (4!) corners, but I think that I played pretty good. (Relatively, that is. I am sure good players could demonstrate what a patzer I am.)
Against the computer, I gave up all four corners again, and I was soon outplayed. Should I try to hold corners? (I haven't studied any Joseki.) Also, does it seem like I let myself get "led around" too much? Any slight help in directing me to the path of enlightenment will be greatly appreciated.
