It's clear PH thought PI had two overcards. He wasn't willing to risk his tournament life on a coin flip, he's never done that if he could help it. At that point he had limped and only had a wimpy 10k in the pot. If he called, the pot odds/SPR wasn't high enough to set mine he probably thought. 16 bracelets I'll give him a little benefit of the doubt. Just a little though.
