This game of Air Poker probably isn't a 1 vs 1, but a 2 vs 2. Ever since the start of Air Poker, the one thing that bothered me the most was, where the hell is Hal(the leader) and Fukurou? The last we saw of them was in chapter 426 where Fukurou was trying to change the password, but Hal also appeared to stop him. Logically, the referees wouldn't allow two such variables to affect this match, so where would they be? The conclusion I came up with is that they are playing the game of Air Poker alongside with Baku and Lalo. Another clue to this is that in chapter 433 page 9, you can see Shion say, "Please forgive me..." Who is he asking forgiveness from? I asked in that chapter if that was the correct translation because it seemed so out of place, and it seems that indeed that is indeed the correct translation. Referees are crazy individuals. Who is one person they would ask forgiveness to? That would be the leader. So probably because Baku lost the first round, Hal had to endure something that made Shion ask for forgiveness.
