Is This Collusion??

Hi there,

Looking for opinions on this if this represents a possible case of collusion. I've removed the players names but note I have had no previous experience playing with either player, and, both players are Russian. I may be pessimistic, but considering the recent revelation from PartyPoker on the colluding on the $109 tournament, I'm skeptical.

This is the SECOND hand in this spin n go
