No trick. The character never had a strength bonus to damage to lose and it was proposed that a weapon always does what it does, that the low strength wouldn't lessen the 1d6 of a short sword.
We also got a little sidetracked by the weapon finesse issue. It seemed odd that a character can choose to ignore a low strength's usual penalty to hit, but then, a character with a high strength using weapon finesse doesn't get both the strength to hit and the dexterity bonus weapon finesse applies, so it does make a strange kind of sense.
Anyway, we had two players and one DM with three different opinions between us, so off to the boards to see what the world thinks. Thanks!
