PT3 told me that both these guys have tried to steal multiple times, they have both lost money since I started playing with them. I was 6-tabling at this point, made both calls and am proud of it

Nice calls.
But I think the first hand would've ended with a c-bet on the flop. Second hand definitely would've been a hrd call to make without the info.
Well Played.
