The turn card is Ace of hearts. John is now smiling to himself as he has just managed to make poker nuts with a flush, his two hearts in his hand plus 3 on table with Ace King high now gives him an unbeatable hand. John bets as he knows he's got nuts but he wants to extract maximum cash from table so he keeps his bet low enough to get called. You still think you are winning with straight, in fact Ace has strengthened that belief as you now reckon John probably has an Ace in his hand and maybe even two pairs.

He's fallen into your trap! Or so you think.

The river is dealt and it's 5 of hearts. This is a blow to you as there are now four hearts on view, so anyone with a heart is beating you with a flush. John is happy with 5 as he still feels he is winning with top flush, while his opponents may also have made a flush and think they are winning. Amy of course is real winner as she has just made nuts with four 5s, her four of a kind can only be beaten by a straight flush or a better four of a kind. There aren't enough connected hearts showing on table to make a straight flush and there isn't another pair showing so it is impossible to make four of a kind.

Amy wins pot while you and John reflect on what should have been.

Both of you held poker nuts at one point in game but failed to realise that poker nuts - and your fortunes - in Texas Holdem can change completely with one turn of a card.
