I agree with 'tekn0wledg' that the bluff on the end was bad, for reasons I stated in my initial post, and for the practical reasons he stated (although they go hand in hand).However, I have to take issue with something else that he said:"I definitely would not chase with a gut shot while heads up. Open ended maybe in the right conditions, but never an inside straight."Never say "never" in poker. What you need to be focused on is pot odds. The size of the pot should be the major factor in almost every decision you make. The larger the pot, the more correct it becomes to play weaker draws. U
