yeac ive played a lot of 5 card draw in my time. Generally position is king, and you need to base a lot of your decisions besed on that. Playing 2 small pair is a bad idea, watch the draw, and watch the players that draw 1 card holding trips, generally dont slow-play.
Err there is books on this topic, gl though. Ill try and write a little more when i get over my hangover.
