(1Y)2Y
This bidding system includes both Michaels and Bailey cuebids. Michaels over fully natural minor suit openings show both majors. Bailey cuebid show the highest and another unbid suit.
Michaels over minor suits
Subsequent bidding is mostly natural since there are already three suits on the table.
| (1♣)2♣- | Michaels, 5+♠, 5+♥ |
|---|---|
| 2♦ | NF, usually 6+♦ |
| 2♥♠ | NAT, 1+# |
| 2NT | NAT INV |
| 3♣! | INV+, usually 3+♠♥ |
| 3♦ | FG, usually 6+♦ |
| 3♥♠ | PRE, 3+# |
| (1♦)2♦- | Michaels, 5+♠, 5+♥ |
|---|---|
| 2♥♠ | NAT, 1+# |
| 2NT | NAT INV |
| 3♣ | NF, usually 6+♣ |
| 3♦! | INV+, usually 3+♠♥ |
| 3♥♠ | PRE, 3+# |
Bailey cuebids
Bailey over major suits is the same as Michaels. Bailey over hearts and quasi-natural minor suits shows spades and another unbid suit.
| (1Y)2Y- | Bailey, 5+♠, 5+ another unbid suit |
|---|---|
| New suit! | P/C |
| 2♠ | NAT, 1+♠ |
| 2NT! | INV+, ask for the lower suit |
| 3Y | INV+, 3+♠ |
| 3♠ | PRE, 3+♠ |
Obviously, (1♠)2♠-3♠ is game-forcing because it bypasses both our suits. Meckstroth advances move the forcing raise to 3♦ and reenables invitation.
| (1♠)2♠- | Michaels, 5+♥, 5+ minor suit |
|---|---|
| 2NT! | INV+, ask for the minor suit |
| 3♣! | P/C |
| 3♦! | INV+, 3+♥ |
| 3♥ | NAT, 2+♥ |
Cuebidder is not supposed to have a stopper. To a new suit advance, I suggest cuebidder swap notrump and cuebid. A notrump rebid shows support while a cuebid denies it.
