categorically says I have no 4 card Major
Playing a weak
No trump system with four card Majors, with
two 4 card suits and 4432 shape and 15-19 points you open 1 of the suit
and rebid in No Trump next- you should not try to show the other suit.
So my own choice in these situations is to open 1 of the Major. as
Majors are so important.
ADVANCED TIP 458
Partner Splinters and you are thinking about going to a
small slam- if your points outside the splinter suit plus partner's known points
total totals 26 or more then THINK SLAM big time.
