I recall reading a poker magazine recently that a tournament diector said he would force someone to call if he was pot committed.So I based my post around that.
Personally was happy that i won the pot uncontested.
(if i'm wrong about what the magazine post said i appologise.I just skim read the article whilst taking a dump)
If you did read something like that I'm sure it would be the other way round i.e. a bigstack getting 20-1 pre and wanting to fold on a bubble.
