Rubensohl

Continuation after opps overcall our 1NT

When opps overcall our 1NT opening with 2♦ or higher, our bids on level 2 in a suit are TP. Double is for T/O. Bids from 2NT to 3♠ are transfers, showing:

- Invitational+ strength, if RE could have bid the suit on level 2; OP with a minimum accepts the transfer,             otherwise she bids naturally (GF); RE's second bid is GF.

- Unknown strength, if RE could NOT have bid the suit on level 2; OP MUST accept the transfer, RE's second bid is GF.

When opps overcall our 1NT with 2♣, Rubensohl is on ONLY when 2♣ shows both M. If it is natural or if it shows unknown one suiter, the system is on, except for the double, which is Heeman.
