Feinberg Likes His Jacks

Feinberg: (x)(x) / {j-Clubs} {j-Diamonds} {5-Diamonds} {2-Spades} / (x)
Lundberg: (x)(x) / {6-Spades} {q-Clubs} {k-Diamonds} {4-Spades} / (x)
Bershad: (x)(x) / {2-Clubs} {9-Clubs} FOLDED

Sam Feinberg raised on third street, and Hakon Lundberg reraised. Mark Bershad called, as did Feinberg. Feinberg bet out when he paired his jack, but Lundberg was the only caller. From there, Feinberg bet on each street, and Lundberg called each time. Feinberg showed {j-Spades} {j-Hearts} {10-Hearts} for rolled up jacks turned to quads, and Lundberg could only show {k-Spades} {q-Spades} {2-Hearts} for two pair and a missed flush draw.
