UTG has 75 chips left (blinds 25/50) and raises all-in (a raise of just 25).

I figured that there was a good chance that they'd have rubbish, and thought K9o had a good chance of leading against the all-in player. If I raised enough to dissuade other players, I'd be getting 2-1 on my money. I thought that other players would think that anyone who re-raised after an all-in must have a good hand (and thus fold).

Is this thinking right? Other players criticised me for making it less likely that this player was knocked out, but i figured that for myself, I'd get great odds on my money after blinds are included.
