UMJOOMO (refined 5♠ 4-5♥)
Playing this with Radu with 3rd Suit GF after 1m-1x-2m
(need a bid with KJxxx Axxxx xx x, partner could have x KQxx xx AQxxxx – here 1♣-2♥-2NT-3♠-4♥)
Note: March 2025, Also on after 1m-(X)
After minor opening with 5♠ and 4-5♥, by UPH, PH or after opponent’s takeout double.
- 2♥ < Invitational, any HCP if non-vulnerable or 55
- 2♠ = Invitational, (note: very rare by PH, so must be 5+ 5+, 9HCP if only 55)
Not doing this and bidding spades then hearts isGF
Opener rebids:
- To Play: P, 2♠ over 2♥, 3NT, 4♥♠, 5♦
- Ace Ask: 4NT ace ask not RKC, 5♣=04, 5♦=1, etc
- Natural Minor: 3♣/♦, natural NF
- Invitational: 3M invites
- Asking 2NT (asks responder range and if 55):
- 3♣-min 54,
- 3♦-min 55,
- 3♥ non-min 54,
- 3♠ non-min 55,
- 3NT natural.
Revised August 2026: 64 or 54 (instead of 55 54), so 4♥ and 5 or 6 spades.
- (Solves the problem after 1m-2♥ of 3♥ and 2♠, always better to go back to spades)
- So 1m-1♠-1NT:
- 2♣ normal relay
- 2♦ any GF
- 2♥ 55 NF (can’t be 4 hearts bc above)
- 2♠ long spades NF (can’t have 4 hearts)
- 1♦-1♠-2♣:
- 2♥ still 4SF, so could still have 4♥
- (Losing showing 55 <GF here, if partner 1354 worse off possibly)
- Also: 1♣-1♠-2♣: 2♥ is 55 NF, use 2♦ for GF
