tourny it all depends on how strong a play you think you are compared to your oppo
I remember a post on Paul Phillip's journal where he had called in a similar hand (ie he was behind but had odds to draw). People were asking why he had done so when he was clearly better than everyone at his table and could have outplayed them later on. He said that the reason he was better and had an edge on the other players is because he would make the call.
