Local swiss teams tournament, last round and last board (36 boards total). Clock is 11PM in Thursday evening and set has been full of boring hands with 2 part score battles(you have won both with ♠) and 3 easy to bid cold games. You are in the top table with 4 VPs lead over your opponents (3rd team is already 14 VPs behind). Both opponents are in top 20 of Finnish master point ranking if it matters.
Carding method in use is
- 3rd/5th leads
- UDCA
- smith echo (high promises some help in led suit)
- First discard o/e (odd encourages, even is S/P)
- Lavinthal
