Obviously I didn't really mean they were the only 2 possibilities - just the 2 I think most likely

The 2 possibilities are that he was bluffing first time round, but has now caught a pair with the king.

Or he's bluffing both times and doesn't understand the need to be consistent - it's a shame you hadn't played a few more hands to see what was more likely.

In this circumstance I'd call, based on the fact that if he was bluffing both times and you fold, he'll never let go of a draw because he'll think he can bully you off the pot if needs be.

One of the best poker strategy books around and as it's geared towards tournament play it seems tailor made for what you're looking for.

I'm generally too lazy to post to more than one forum, but after catching up on this project I just had to say it's one of the best forum threads I've read - both in terms of it's content and Rob's style [of writing and towards life in general].

What is the website address? - When can I sign up?
