Strategy vs stealers?

[bufrakbh]

Hi

I just played 0,5/1 limit at Pacific. At my right was one player who kept stealing the pot, and later there was another to my left. The other players at the table kept folding, so Im not completely sure, but they kept winning hands without showing them, when I looked at the history, and when they sometimes showed their cards they had something like a lucky 9 on the river to win with a pair of 9. My instinct was to just play "theorectical" correct (or as close as I currently can). However I kept getting crappy cards, and in the end I began considering raising there bets, even if I didnt have any special cards. At some point I went a little on tilt, and shortly after stopped playing as I was getting unsure how to play.

Do anybody have any comments, that comes to mind when you read this?
