home game - we play two decks to be more efficient (red deck / blue deck rotating).
9 players around the table. one of the plays..
pre flop 5 players call BB.
flop comes 234. one player goes all in. the other calls (not all in). everyone else fold.
all in has KK, the other has 88. board is 2 3 4 5 J
KK wins and take the pot. that moment one of the not involved players realize that 88 plays with red cards while the blue deck is being played. apparently it is the exact previous hand of the player with 88.
his real cards (blue deck) is also in front of him face down. they are 96. makes him straight and beating KK.
how do you resolve this issue pls. who wins? do you cancel the play? how do you split the pot? how about all other players who called BB and folded after player with 88 called all in of player with KK.
