mr.ed, your scenario above is NOT the OP's scenario at all. No one has suggested covering the other side in your scenario. This is probably going to sound mean and it is honestly not meant to be mean but this is where reading comprehension and communication is vitally important. The OP (which apparently in recent posts appears to have softened his position) originally stated that given an arb (wagers at the same moment in time) that it was always a waste to wager on the -EV side and that statement without caveats is just not true which has been pointed out by some posters with examples as well. Joe.
