This is clearly nowhere close to evidence of foul play- this is a good but somewhat standard river call from hero. Bears double float/shove screams of two overs taking a desperate stab on the river.
fwiw i've played a few of the pokertube tourneys with bear and found him condescending and self rightious. There have been a few series events (10 tournament) where bear consistently busts out early being continually trumped by novice players.
His analysis usually falls short and this is when he is reduced to labeling his oppents fish and berating their play in super standard spots.
i recall one spot recently (excuse the quick recap)
bear is in middle position in an 8 handed tournament table with 77. blinds 50/100
utg + 1 opens to 300- bear pops it to 8, the button flats and utg +1 flats
flop comes something like 6 K Q rainbow. utg + 1 checks bear makes it 1500 button goes out and utg +1 moves in for 300 more and bear has to call.
utg + 1 turns over k10sc and holds- bear goes off in a massive rant about how utg + 1 is a massive fish shouldn't be playing poker bla bla bla- he insults the guy pretty hard.
As bear claims "theese tourneys are a bit of fun. not too serious for a higher stakes player like me"
then stop being a massive ****
