What to adjust to
In a club competition where you draw for partners, I as N felt disadvantaged in the following sequence:
S W N E
1H 3C 3H 4C
- 4D - 4S
- - 5H all pass
There were no alerts, and before bidding 5H I asked E about the 3C bid who explained that he thought it was natural until he heard 4D, after which he thought it showed D & S. 5H went -2 for 0/10, whereas 4D or 4S makes. Would I be entitled to an adjusted score, and if so to what?
South: 65, KJ643, Q4, AQ76 North: 872, AQ752, 52, K98
West: KQ109, 109, AKJ93, 53 East: AJ43, 8, 10876, J1043
Has West acted on (UI)?, and how should they act at the second turn to bid?
