Heimiller Bets in the Dark

Nick Petrangelo raised to 55,000 and it folded around to Dan Heimiller in the big blind. Heimiller cut out a three-bet to 135,000 and Petrangelo called.
Before the flop was dealt, Heimiller instantly shot out a bet of 150,000 in the dark. The dealer fanned and action was over to Petrangelo. He sat thinking for well over a minute before he moved forward calling chips. The
hit the turn and Heimiller checked. Petrangelo knocked the table back and the
finished the board. Two more checks occurred and Heimiller flipped up
for king-high. Petrangelo showed
for top pair and he was awarded the pot.
"It was in the logo," said Petrangelo, remarking about how Heimiller's dark bet was in the PCA logo on the table. "I didn't see you bet dark."
"Yeah, I got it in before the cards came out," said Heimiller.
"You're a f*cking wizard," quipped back Petrangelo as he stacked his new chips.
