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.
