Rubensohl III
PITBULLS:
Still another version of Rubensohl by
Jacobs/Maksymetz . Their version combines Lebensohl with Rubensohl . They keep
2NT as a transfer to clubs but not
necessarily clubs. They use spades ( after heart overcall ) or
transferring into spades ( after a
spade overcall ) as the club hands.
This opens up 2NT as a club relay and they can invent more meanings to bids
after that. They also use
Rubensohl after a 2♦ overcall
also which Kantar does not.
