There is nothing unusual about this isolated hand. As the original poster said, he was obviously likely to be beaten.
What makes this unusual is the amount of times hands similar to this happen. If I go into a game of Prominence Poker and play for an hour it's almost guaranteed I see a couple of hands exactly like the one described.
I will also so crazy high amounts of hands have several people with multiple super good hands like a flush, three of a kind and a pair of aces all in the same hand.
Or an ace on the table and three people have aces. Countless straights won on the river. (This game seems to hand out a straight every other hand).
No other poker game I have ever played or real life poker I have ever played has consistently had this amount of crazy hands happen.
