What we recently did over at DTB was get a group together to play a small private game -- I think we had 12 or 14 players. Afterwards everyone emailed me their HHs, and I wrote a little program to merge all holecard data into one master HH. Greg Jones/zerosum79, a SnG coach over there, then made a video with commentary of running through the merged HH with a replayer. This captured everyone's holecards whether folded or not, and is a great group coaching tool. I think that was the second one they had done, but was the first for me. Greg had manually merged in the holecards the first time, which is quite tedious, but with the tool I wrote it's a lot easier now, so we expect to do more in the future.
I offered up the use of the tool here in the event we wanted to do something similar here at CC, and see if Greg or one of the other coaches that visit here would do the review. Or even one of our own stronger CC players for that matter -- we have several that are more than qualified.
