Walking around the Brasilia room we heard a dealer over at Matt Perrins' and Alessandro Speranza's table yell out "Winner on 11!". We came over to see what had transpired and were privy to a board, with a players exposed.
That two pair, tens and fours belonged to Matt Perrins who had just delivered the knock out to Alessandro Speranza. Perrins shared with us that he three-bet preflop and received a call. Perrins then said he bet every street and received a call every step of the way until eventually he put Speranza all in on the river. Speranza made the call and was eliminated as he couldn't trump Perrins' two pair.
