LOL - I'm guessing it was an APL / NPL tournament?
I deal for a job. So self-dealt tourneys put me on life tilt, and stuff like is just one of the reasons why.
If you're retarded enough to forget to burn a card, you need to take out the card that was supposed to be burned, make sure the entire table has seen it so everyone's got the same information (and knows how stupid you are), then use it as the burn card and put the next card in the deck onto the board, where it was meant to be in the first place.
You
don't reshuffle the deck - you just correct the mistake. For one it's faster and for two it avoids any arguments over
"Oh but I would've won if the deck hadn't been reshuffled blah blah blah".
In fact the only time you're supposed to reshuffle in the middle of a hand is if you're playing draw and you physically run out of cards for the drawing round, in which case you reshuffle the folded
hands and use those.
As to how the same card managed to get reshuffled then dealt twice... I dunno. Was the guy (or one of his friends) actually in the hand and if so, did the cards help him? If so I'd definitely be suspicious: it's certainly possible for people to execute false shuffles and placing one specific card back on the top of the deck is probably the easiest one to do. I think even I could manage it.
It's also possible it's just one of those crazy coincidences.
Point is though, he should never have reshuffled in the first place.
