Ha, such original chatbox abuse.
This is a difficult hand to analyse. With standards at this level being so variable (especially heads up) a lot does come down to your specific read, so most of the below will be pretty general.
Pre: Much prefer the min raise, if you think you have an edge on your opponent then you should want to give yourself more wiggle room post-flop. You should be using the first 5/6 hands to test how Villain reacts to clicks. I.e. click the first 3 buttons you get with ATC, look to get to showdown if at all possible and that can help dictate your subsequent HU strategy. If they fold to a min raise, then you never need to do any more than that. If they seemingly can"t pass, then (depending on chip stacks) I might test out 2.5x, then 3x opens, or even vary my opens depending on hand strength if Villain is poor. If this still isn"t working, then I significantly widen my limping range and play post.
Given you"ve just doubled up twice, you"ve not had the opportunity, so start now. Therefore I hate 3x with Q6o, it"s behind 2x, fold, limp in my preference list. By 3xing pre you"ve greatly reduced your options down the streets.
Post: If Villain is straightforwardly weak (common oppo type) then a c-bet is fine to get value from a J, T, 9 and XXcc, given that it should be fairly obvious if they"ve hit. If you do bet, half pot is fine. If this guy is aggro spewing, overvaluing weak hands/draws then I definitely prefer a check for pot control/deception (largely the former). I"m betting most turns if checked to and calling near 100% if he donks. I"m usually expecting to get one street of value for this type of hand, maybe two against a poorer opponent.
A bet achieves very little on the flop. Strong hands call/raise, mediocre-strong(er than you) hands call/raise, mediocre-weak hands call minimum, might raise. All draws call/raise and only air folds. You can"t stand a check-raise, and imo you can"t "protect" your hand, regardless of how much you bet. So many hands call, and there are so many different turn cards that are bad for you you"re not getting any information either. The only information you"ll get is if he has air and folds - and you"ll win the pot against this part of his range later on (unless he bluffs 2 streets, wp if he does, move on).
As played, barf spot on the turn. Some villains can easily have A9/AT here, he could be slowplaying something on the flop and is now worried about the club draw. Most obvious thing he"s repping is the flush - it"s down to your read on the Villain. Based on your previous play with Villain I hope you have some kind of feeling whether they"d check/call flop then lead out with a flush. Realistically, you only beat a spewy bluff here (probably pair+SD that turned the FD) - you should probably fold.
Edit: I"d previously talked absolute b******s about the turn (see Steve"s quote for just how bad), now clarified 
Key is that any missteps early in a hand can have huge consequences later on. I.e. If you 2x, everyone makes the same % bets and you reach showdown lose, it costs you 20.5k instead of 30.3k. If you 2x/check/call/call vs the same % bets then it"s less than 10k.
