What was the pre-flop action? How big is the pot? And do I hate your guts?

It is almost a flip on the flop. I see people call and go all in on the flop in that situation for many varied reasons. I have done it myself on a few occasions. My reasonings, I felt lucky, It's almost a flip, I didn't like the person, I was tired of folding, I felt like gambling, It wasn;t that much more, pot odds, HAHAHAHA.. That is poker, How many poker pros have we seen in high stakes tournaments do it. I feel like your question is not real.

How big was a $400 bet compared to the pot? Was the Ace a diamond? How many players after me? How deep am I and how deep are the players left to act? Do the cards give me a back door straight draw as well?

I don't call anything until I get more details. What was the pot? How many players? The stacks. Something about the players. Will they pay off if you hit?
