assume they're out of it Ok, here's my somewhat complicated answer. I bid 1 dollar more than the leader has currently if it means that if he's betting enough to shut me out he'll finish lower than me if we both get it wrong. Here's a scenario like what I'm describing: Me-7600, Him-10000. I bid 2401 here (1 dollar more than he has). He has to bid 5201 in order to shut me. So if we both get it right, he wins of course. If we both get it wrong, I win. If I get it right and he gets it wrong, I win. Also, if he bids 0 in this scenario because he knows nothing about the subject, I still have a way to win, while if I bid 0 that isn't available to me. If I only have 6000 to his 10000, I bet it all. Bidding 4001 won't help here because he doesn't have to bet enough for it to matter if we both get it wrong. The only real way to win in this scenario is to get it right and for him to get it wrong, and so the best thing to do is maximize your payday if that happens. If the 3rd player becomes a factor, there are lots of different strategies to use depending on the situation and how close everyone is. The player in 2nd always has a really tough bet in those situations (as opposed to 3rd place, where you bet it all just about every time, and 1st place, where you bet just enough to shut the others out just about every time). You must be a very good NL hold 'em player. :)
