Desperate Meets Desperater
Mueller bet out on the flop and then called the raise from Garaventa; he also bet out on the turn (a call from Garaventa) and on the river (another call).
Garaventa turned over and what Mueller was getting so aggressive with will forever be shrouded in mystery, as he mucked, leaving himself with just 60,000. Garaventa meanwhile is only slightly better off on 85,000.
