I raised 4 times the big blind in a $2/$4 NL game. I flopped a set of Jacks. He had J9. I did a weak bet. He reraised. I reraised him. He called. Then I made a pot size bet. He calls and rivers a gutshot straight from his nine. Ridiculous!
What did I do wrong? Did I slow it down too much? Presented too much weakness?
