yeah, after making a transition into playing some cash recently and working with a good cash game player I found that my post flop play was laughable.  No wonder I always reg at the 59 minute mark for tournaments.  Playing a ton of 100 bb deep poker really opened me up to all the variables of post flop play.  Hand ranges are super important, things like capped ranges and so on come into play a lot more, as do recognizing spots to 3-barrel/ spots to give up.  In general, tournament players play flops as well as cash players, but at the turn and river we become more lost.  I think Wein did a video on river play which was good, but I agree that a post flop play with more focus on deep stacks- 75bb+ would be great.  Maybe one on 3-bet pots?
