Thanks for the replies! I think I was upset because it cost me the tournament. As I said, I'm not used to tournaments. If this were a cash game I'd simply just rebuy and keep playing.
No read = fold. It's easy for me to forget this underlying concept a lot of the time. If villain raised he either has me beat or is bluffing or is playing really poorly with the few hands that I am ahead of. With no read I should be folding regardless,... because I should be assuming that villain bluffs or has a worse hand a very negligible amount of time. Is this correct reasoning? I kept thinking that I would be in such weak shape, chip wise, if I fold. But in a tournament being wrong means busting
I thought about checking behind after the fact,... I do agree that it might be a better play. However, I had it in my head that whenever I have to decide between checking and betting, I always go on the side of aggression. This has served me well in cash games, but perhaps I should err more on the side of conservativeness in a tournament?
Although I lost, this is good experience and I'm now a better poker player because of it. Thanks again for the discussion!
