We have kept some of the asking bids in our precision system but it seems most precision pairs have given them up. We use transfer like positives. Accepting the positive implies a fit and asks AK controls like the old CAB. Following this start we can make side suit asks or trump suit asks, like the old epsilons and gammas. After a transfer positve, accept, control ask answer, we use 2NT as a Jacoby 2NT like bid using Larry Cohen's alternative Jacoby answers. This works well. These bids don't come up often but when they do, they can be helpful. If I was playing with someone who hadn't played a big club before, I wouldn't bother with any asking bids.
