Worst BBJ winner

[DarkMagus]

42o should be able to do the trick.

Board 22233
Opponent 33

You have 22224
Opp has 33332

I'm not 100% sure whether this qualifies, but it should, since both hole cards do take part in the losing hand - the kicker is part of the hand, after all.

edit: this also works for 72o, if you want to work in terms of worst full table hand rather than worst actual hand value.
