In Response To: Another "hit or not?" problem (Timothy Chow)

I didn't hit here, even though I knew a close race without cube access was not a very attractive proposition, because the cost of getting hit back seemed too high. GNU 2-ply slaps me with a 0.046 error, but the difference between the two plays shrinks upon rollout.
