We were playing with couple of friends today and I hold this major monster. We played a fun system called sports club which has something like polish clubs 1♣ so this was obvious sports club opener.

♥K is on the right side so 6♠ is practically showdown. We ended up making 5♦XX +1. Losing one imp since opponents found "sacrifice" in 5♦XX :blink:
