i do this often i liek to change up the bids so that it keeps the leader on his toes and he cant get a BRAINLESS win! if there over 500 points and the bonus can make a difference i will sometimes bet 1 or even all my points. heres an example.
1. Vikings 513 (-512=1+500= 501)
2. Pedro 511 (-2=509)
3. Nothingness 500

Now vikings thinks he can just bet 512 and win for free, but not if i bet 1 and pedro bets 2. this makes the #1 over analyze this situation and could change his bets in future ponds. So Pedro is rewarded for watching my tendencies. i only do this every so many ponds, as to not be too predictable.
