We happened to be watching at Table 275 as Sumanth Reddy put out a massive check raise. His opponent shoved a bet of 20,000 into the middle on a board after Reddy checked.
When the action got back to Reddy he put out a massive raise making it 60,000 total, essentially putting his opponent all in.
Reddy's opponent took his time to figure out what it was he wanted to do, he took so long in fact that another player at the table called clock on him. It wasn't until the floor started counting doing "10.. 9.. 8.. 7.." that Reddy's opponent finally folded.
