[The Deuce]

None of the plays you described are really that bad. Unless of course you only go all-in preflop with top five hands, and he still calls with KT, etc. Here's what you need to do. You can't not bluff heads-up, or a guy like this will eat you alive. You should be semi-bluffing constantly, being really aggressive with a lot of apparently weak hands. Like mid and bottom pair, which will be good quite a bit more often than you might expect. I raise 3 and 4x the big blind with Q5 and worse. Heads-up is all about aggression, hand-reading, and just stone cold balls. ABC poker is the last thing you need.
