I had a long discussion of greatest bulgarian bridge theorist uncle Bill. Some of ideas are mine, but general direction was given by him.
Method "BM2SC" of continuation after 2 suiters:
With RHO silent:
Direct bids in shown suits are negative(competitive), jump fits are preemtive(or mixed).
Unbidded suit without jump is natural and NF but inv, not sign off. Unbidded suit with jump below/above game show solid suit, GF with slam interest, jump at game denied slam interest.
2NT(or 4NT without jump after leaping michaels): any inv hand or strong hand with lower suit(m) fit or strong hand with unbid suit. P describe his hand by paradox bids (skipped bid means higher play at skipped suit).
3NT: to play (or preemtive raise without any defense if you play R/S method).
Cue bid:
-if 2NT(4NT) is available: limit+ raise of higher suit (M).
-f 2NT(4NT) is not available: : limit+ raise of any suit, paradox responses
RHO bid: like silent RHO, except:
Pass after opps dbl: equal negative choice or strong hand for penalty double later.
2NT: inv+ raise lower suit(m) or strong hand with unbid suit.
DBL/RDBL:
-if 2NT(4NT) is available: limit+ raise of higher suit (M).
-if 2NT(4NT) is not available: : limit+ raise of any suit, paradox responses
Cue bid: slam interest, any hand, paradox responses
Examples:
(1♦) - 2♦ - p - ?
2♥/♠: negative
3/4♥/♠: preemptive
2NT: any inv, paradox continuations
3♣: nat, NF, inv
3♦: fit ♠, limit raise+
3NT: to play (or R/S weak preempt)
4♣: solid or semi solid 6+♣, slam interest
4♦: fit, slam interest, any M, paradox continuations
(1♦) - 2♦ - (DBL) - ?
Pass: equal choice or strong missfit
RDBL: fit ♠, inv+
2NT: fit ♥, inv+
(1♦) - 2♦ - (3♦) - ?
DBL: inv+, any, paradox responses
(1♠) - 2NT - (p) - ?
3♣/♦: negative choice
4/5♣/♦: preemptive
3♥: nat, NF, inv
3♠: inv+, any, paradox continuations
3NT: to play (or R/S weak preempt)
4♥: to play, limit
4♠: fit, slam interest, paradox continuations
(1♠) - 2NT - (DBL) - ?
Pass: equal choice or strong missfit
RDBL: inv+, any
3♠: slam interest, any, paradox continuations
(1♠) - 2NT - (3♠) - ?
DBL: inv+, any, paradox continuations
4♠: slam interest, any, paradox continuations
(1♠) - p - (1NT) - 2♦{5+♦-4+♥}
(p) - ?
pass/2♥: negative
3/4♦/♥: preemptive
2♠: fit ♥, inv+
2NT: fit ♦, inv+
3♣: nat, NF, inv
3♠: slam interest, any, paradox continuations
3NT: (or R/S weak preempt)
(1♠) - p - (1NT) - 2♦{5+♦-4+♥}
(DBL) - ?
RDBL: 3 fit ♥, inv+
2♠: 4+ fit ♥, inv+
2NT: fit ♦, inv+
(1♠) - p - (1NT) - 2♦{5+♦-4+♥}
(2♠) - ?
DBL: fit ♥, inv+
2NT: fit ♦, inv+
P.S. Ben, on 2 suiters 2NT must have opposite meaning (minor fit instead of major fit) because level and right sided NT contracts. On 1 suited overcalls still normal meaning of 2NT: on major constructive, on minor preemtive/gf.
