Hello, I bid 1club with 12pts, west passed, my partner robot (north) bid 1Heart, east bid 1nt then west bid 2 spade and my robot (north) doubled with 9pts. Can anyone explain why my partner robot bid Double here(I am unable to attach photo). We couldn't defeat the opposition and ended losing even more points 670. I couldn't overrule the robot so couldn't prevent its bid. Can anyone explain this to me please ?
