There's always going to be some amount of guesswork on this hand. You can't expect to get them all right. Auction goes something like 1h-1s-3c-3n-4c-4h, does partner have xxxx Kx KQxxx Jx where slam is quite good, or does he have KQxx xx KQxxx xx where 5 level is in jeopardy?
6-6 hands are super rare so normal systems aren't really catered to bidding them accurately. So all you can really do is show as much of it as you can, and at some point you or your partner have to take a guess. How can you find out if partner has CJ which might be huge but not DA which might be basically worthless? Most systems cannot diagnose these things at a reasonable level.
So anyway, the basic plan is to bid 1h, then 3c and 4c if partner doesn't raise hearts right away (lacking competition from the opponents; with vigorous competition you might end up bidding 4c and 5c or something like that). Now with some hands partner might be able to show real support for one of the suits and you can just gamble that he a couple useful cards and bid 6. If he just takes a reluctant preference to 4H, probably odds favor giving up, but one would might have to run a simulation to be sure of this.
Just because some guy happened to get to the right slam and opened 2c doesn't mean at all that he was being clever; he might have just gotten lucky. Is the slam a good one, high percentage, or does it require a favorable lie of the opponent's cards? Would he have gotten to the same slam if partner had slightly different cards but same bids, and would it still be good or would it transform to terrible if partner had a different combination of high cards that would choose the same responses?
The reason people don't open 2c is because it's unlikely to help you (pass out being so extremely rare), and it is more likely that you can bid hearts than clubs and clubs by the 4c level if you start with 1h level than if you start with with 2c (since opps may jack the bidding in spades and your first heart bid is at 4 level and you haven't mentioned clubs yet, or even if opps are silent partner may do something inconvenient by bidding spades or diamonds and again you don't get to bid clubs first time until 4 level).
