Adapting Conventions to Precision (Part 2)

A few weeks back, I was thinking about how useless standard Jacoby 2NT is when playing precision. Even Swedish was not much of an improvement, since it still was made for hands up to like 20 HCP. So over the course of the next few days, I devised a structure for Jacoby that fit perfectly with a precision system. Since 1M openings are limited to 15 HCP, with this structure you can show your HCP range within 1 point, and show shortness or the lack thereof and all below 4M. So, here is another improvement for all you precision players:

1M - 2NT:
3♣: 10-11 HCP or 8-9 HCP with Distributional (5-5+) opener
-----3♦: Asking
--------3♥: 10-11 HCP with No Shortness
--------3♠: Distributional Opener (5-5+) 8-9 HCP
--------3NT: Relay Asking 5 Card Suit
-----------4♣: 5♣ + 5M
-----------4♦: 5♦ + 5M
-----------4♥: 5oM + 6M
--------3NT: 10-11 HCP with ♣ Shortness
--------4♣: 10-11 HCP with ♦ Shortness
--------4♦: 10-11 HCP with oM Shortness
--------4♥: 8-9 HCP 6+M-5+m
3♦: 12-13 HCP with Shortness
-----3♥: Asking
--------3♠: ♣ Stiff
--------3NT: ♦ Stiff
--------4♣: oM Stiff
--------4♦: Stiff in Both Minors
--------4♥: Stiff Minor + Stiff oM3♥: 14-15 HCP with Shortness
-----3♠: Asking
--------3NT: ♣ Stiff
--------4♣: ♦ Stiff
--------4♦: oM Stiff
--------4♥: 2 Stiffs
3♠: 12-13 HCP without Shortness
-----3NT: Asking
--------4♣: 5332
--------4♦: Side 4 Card Minor (22)
--------4♥: Side 4 Card Other Major (22)
3NT: 14-15 HCP without Shortness
-----4♣: Asking
--------4♦: 5332
--------4♥: Side 4 Card Suit (22)
4♣: 12-15 HCP with ♣ Void
4♦: 12-15 HCP with ♦ Void
4♥: 12-15 HCP with oM Void

I may post some other systems and things later on, but I don't have too many other significant improvents on a precision system that I have come up with... I'm playing the junior trials this weekend, and we will be using these systems... I'll have more on that when the time comes...
