Dimitrios Nanos and Paul Otto were heads up in a pot of around 30,000. The flop came 9♦9♠Q♥.
Nanos in the big blind checked. It took Otto a few seconds to check after.
On the turn 2♥, Nanos took a few seconds to consider his options and decided to check again. Otto mulled over the situation and knuckled.
Finally, on the river 10♥, Nanos, looking directly at Otto, checked for a third time. Otto immediately checked after.
Nanos was visibly frustrated and was shaking his head when he threw his cards on the table to show J♥J♠, prompting Otto to muck his hand.
