I don't like it.

You miss a probable call from Aces.

Let's say aces comprise 1/3 of CO open raising hands.

If we assume
1) He will call with A-high (resonable)
2) He won't bet A-high if you check (resonable for most opponents)
3) He won't call with hands that are not A-high (not far from resonable)

then he needs to bluff bet 50% of the time he doesn't have A-high for your play to be good.

Since I think the four assumptions have been more biased towards checking than is correct, I think the real percentage he needs to bluff is more like 60%+
