The 42 group is the only group still active during lunch at work. So I play with them unless it is Tuesday and Tichu makes. Our team was down 0/4. Then we slowly fought our way to 4/4. And I get the following hand: 6:6 5:5 2:2 0:0 6:4 and two low tiles (maybe one was 5:1). I think about for for a while. And then I decide to plunge. This is a three mark bid where you have four or more doubles and your partner calls trump and leads. My partner perks up and bumps the bid up to four marks because he has the remaining 3 doubles and something to transfer the lead to me. Kinda flawed in a way since the game is played to seven marks.

I have also seen people overbid when they are behind just to determine the trump suit. And then get set because they have a poor hand.
