All players have 10,000 PKD. The only info i could find on the PKMN currency, describes them as being called "Pokemon Dollars", while having the value of Japanese Yen. So i'm going with 1358456's theory on it, of 200 PKD, to 1 USD.
This takes place 8 years after HGSS.
"Deal the cards." Blue commanded Gold. He burned the top card and dealt each of them a hand of two.
When she picked up her hand, she noticed the Jack of Spades and the Queen of Hearts. While Blue wasn't on Gold's level as a gambler, she knew her hand was bad and decided to fold during her turn. As she had the big blind, she still lost some money. (Blue: 9500) Red had a pair of Tens; one of Spades and the other of Diamonds. It was his turn to be the small blind, but he was confident he could earn his money back with his current hand, and then some. (Red: 9750) Green held the Ten of Hearts and Four of Spades. Yellow had the Six of Spades and The Eight of Clubs, and decided to play it safe by folding when her turn came.
Crystal possessed the Queen and King of Diamonds. She briefly wondered how Gold had talked her into joining a game of strip poker, of all things. He was just so persuasive, when he wanted to be.
Silver, on the other hand, had the Four and Five of Clubs. He knew it was a decent hand, but likely to be outranked, leaving only the option to fold.
Ruby had the Three of Clubs and the King of Hearts, Sapphire a pair of Aces in Clubs and Hearts, and Emerald the Five of Spades and Diamonds.
Gold himself carried the Jack of Clubs and the Seven of Diamonds.
"Make your bets." Gold smirked.
"I'll bet 400." Red said confidently. (Red: 9350) (Pot: 1150)
"400 from me too." Green said calmly. (Green: 9600) (Pot: 1550)
"I fold," Blue said, handing her cards to Gold.
Being inexperienced in poker, Yellow decided to follow Blue's lead. "I'd like to fold too." she whispered, passing her cards to Gold.
"I'm folding." Gold stated flatly.
"I'll raise by 4000." Silver declared, the ghost of a smirk creeping across his face. (Silver: 6000) (Pot: 5550)
"I'm taking this bet." Crystal replied. (Crystal: 6000) (Pot: 9500)
"I fold." Ruby mentioned, laying his cards facedown.
"I'm in!" Sapphire shouted. (Sapphire: 6000) (Pot: 13500)
"I'm out too." Emerald said smoothly.
"I'm in." Red sighed. (Red: 6000) (Pot: 17500)
"I'll fold." Green stated simply.
After the round of betting ended, Gold placed the flop down, consisting of the King of Spades and the Seven and Nine of Hearts.
"I call." Red said after perusing his hand.
"Calling here, too." Silver muttered.
"Me as well." Crystal politely mentioned.
"And me!" Sapphire yelled.
"Well, then." Gold smirked, burning a card before revealing the turn: the Queen of Clubs. He knew that whoever won this hand would most likely win the entire game, and he knew his opponents realized this as well.
"Any other bets?" Gold asked, fulfilling his duties as dealer.
"Nope." The players replied in unison.
"You're really anxious to get this game over with, aren't ya?" Gold smirked once again.
"Well!" he said, burning the final card, and placing down the Six of Diamonds as the river card. "Reveal your hands." Red had a pair of tens, unable to make anything else from the cards on the table. Silver cursed inwardly as he placed his cards on the table, merely an Eight card short of a Straight. Sapphire grinned and showed the group her Pair of Aces. Her smile soon faltered as Crystal put her cards down, revealing Two Pairs: Kings and Queens.
"I win!" Crystal giggled, pulling the pot to herself. (Crystal: 23500)
Having lost that round, Red took off his hat, Silver his boots and Sapphire her bandana.
"Let's move on to the next hand."
Yeah, I tried to make it as accurate to regular Hold 'Em, as I could, but if there's still any inconsistencies, chalk it up to PokeSpe-Verse Hold 'Em being different from real-life.
