A method of ace asking for use in awkward situations:
- when a minor-suit fit has been established, a jump to four of the cheapest unbid suit asks for aces;
- when partner's last bid was 3NT, a bid of four of the cheapest unbid suit asks for aces (but if all suits have been bid, then 5 asks for aces.)
In both cases, the responses to the ace asking bid are similar to Gerber, i.e., in successive steps. Thus:
- step 1 shows zero or four aces;
- step 2 shows one ace;
- step 3 shows two aces;
- step 4 shows three aces.
To ask for kings, asker must repeat the suit used to ask for aces.
