I did find it useful, possibly because I was an absolute beginner at the time and was mainly playing
freerolls, so things that seem to be obvious now (such as "donk bets") came as a bit of a surprise.
Also when you are multitabling and playing thousands of hands a day it is surprpising how often those exact same sort of situations do come up again, even if you think it might not ever happen again.
We're not talking about bad beats here, nobody really wants to hear about those, we're talking about a situation that you have been in and thought "not really sure what the best thing to do here would be". You just show people here at CC the hand up until that point and ask them:
1) Would they have played it the way you did this far?
2) What would they do next?
Quite often it will be down to the bet sizing that has been used on a previous street or something like that, and the chances are that some people will disagree on the best way to play it or how to proceed, which can give you ideas of alternative approaches for tricky hands.
I agree that it's quite a lot of effort to provide them with all the info, but I did find the feedback very useful. It also encouraged me to take tons of notes about other players at the tables in order to be able to provide the background info needed, that in turn helped me when I had another tough decision to make against that particular player in future. I started taking a screenshot of a tricky hand in order to have their HUD stats available and to remind me to post the question about the hand at a later time.
