Out second.
The other guy ran really well when it mattered, and twice survived all ins when at risk with 40/60 holding. That said though, he played really well and never made a mistake headsup.
In the end, it came down to a mahoosive pot where Niall held A4 and 4bet shoved, the other called with 66... and despite a flop that gave Niall a flush draw, a gutshot draw, and the overcard (15 outs), the 66 held.... a couple of hands later, and it was over when Niall"s A2 was no match for A3 (aipf), and a 3 on the flop.
