A few interesting hands (you play a 12-14 NT, 2/1 and a lot of gadgets):
1. ♠AKT8x, ♥Qxxx, ♦Jxxx, ♣void.
I (as your partner) open 1♣, 1♠ by you (apparently valuing this hand to be slightly too good for a reverse flannery call of 2♥).
For some reason you decide to raise to 3♦ instead of the systemic rebid of 2♠.
Pard now bids 5♣. What does he have and what is your call? If you strongly disagree with 3♦, what would your rebid be over 5♣ (after 1♣-1♠-2♦-2♠ - 4♣ - 4♦ - 5♣?).
2. ♠Qx, ♥KT98, ♦ATxxx, ♣AQ. You open 1♦. 2♥ by pard - Reverse Flannery - 5+♠, 4+♥, 5-9 points. Your systemic options are: 2N - asks shape, 3♥ - invitational.
3. ♠KTxxxx, ♥, xx, ♦Q, ♣AQxx. Pard opens 1N (12-14); penalty double by RHO. What is your strategy? (2♠ is natural and non-forcing (but better than direct xx), xx shows a single suiter, pass forces redouble (to play or to show ♠ + another).
