Why not find and post the full hand in the sample hands board pogodon (give me or someone a shout if you need help with converting the hand history into the forum format).
Our experienced hand judges and other members of course will be happy to look at the hand and provide guidance on how they would've played it.
Sometimes in the heat of battle it's easy to overplay or even underplay hands, the judges will help you to get maximum value from certain situations via bet sizing etc which will only go to help you in the long term.
Equally it gives you massive confidence boost if they agree with your line but you were just plain unlucky (which also happens... a lot).
Don't be disheartened though my friend, this is just 1 of many tournaments that you will play. I had flopped quads beaten in a tournament tonight... to runner runner higher quads although to be fair he had over pair (two pair) on the flop. Sometimes the money goes in and it's then in the lap of the poker gods. I just laughed tbh, nothing else you can do, can't dwell on it as was in other tourneys at the time too. Will post it soon though to check whether I could've done anything better.
Keep your chin up buddy and gl next time.
