I wasn't involved in the hand, but I think this is the worst series of bad beats ever.
Player 1: KK
Player 2: 44
Player 3: AQ
Player 4: Q5
Preflop commentary: Pretty much in order, the players have the best to worst hands. All of them are all-in. Note that 3 has 4 dominated with the shared Q.
Flop: J J 4
Player 2 takes a huge lead. Player 1 takes bad beat #1.
Now, after the flop, the players would win side pots in this order:
Player 2
Player 1
Player 3
Player 4
Turn: 5
Turn commentary: Now, if there was a side pot between 3 and 4, 4 gives the next beat on 3. Now the players are in this order:
Player 2
Player 1
Player 4
Player 3
River: 5
River Commentary: THE HAMMER! Player 4, who started out with the worst hand, gives the brutal beating to the other 2 players ahead of him with the 5's over jacks beating 2's 4's over jacks fh. Poor KK got cracked twice in this hand.
Final standings:
Player 4: 5 5 5 J J
Player 2: 4 4 4 J J
Player 1: K K J J 5
Player 3: J J A Q 5
