SAYC means differnet things to different people (i.e. its not as well known as you would think)
>11. Grand slam force
I would not be surprised if this gets confused with Pick a Slam.
>8. D0P1
Without discussion you are playing with fire.
>b. Strong jump shift response (1D-p-2H)
probably the majority use Weak Jump shifts, so I would be scared to use SJS without discussion.
>12. Do we have stopper? (1D-1H-1S-P. then 2H asking for stopper)
Is it a stopper ask, or showing a big hand? Or both? Since pard has bid a major, not a minor. Maybe you have 3 card spade support? I wouldn't want to assume this.
You don't have Blackwood listed. Is it regular? 0314? 1430?
>6. Last Train convention
I would never assume this.
In general I am extremely wary of conventions with pick up pards, even "advanced" ones. One "advanced" pard didnt play negative doubles
Probably a big clue is if some lists in their profile any of the following:
- stayman
- 2 Clubs strong
- transfers
they are not advanced
