The action folded to Juha Helppi, who opened to 48,000 on the button. Jason Mercier tanked for a bit then three-bet to 94,000 from the small blind. After the big blind released, Helppi quickly moved all in.
Mercier asked for a count - it was a 483,000-chip bet - and after mulling it over for a bit, he called.
The flop gave Mercier a leading pair of nines, but Helppi still had outs to catch up. The on the turn was a brick, but the fell on the river, giving Helppi a pair of jacks and the win.
He doubled to over one million chips, while Mercier is back under 500,000.
