Playing PLO, flop top set with A[AA] against opponent that has T[TT]. He turns the case T. Lose a 3 way all-in pot worth about $100+; other guy had wrap str8 draw.
Playing NLHE, I'm on button with AA, raise and reraise in front of me and I push for my last $25 (.25/.50). Second raiser calls with TT (my suits even) and rivers a T; lose a $50+ pot
One hand isn't a problem but these 2 within about 15mins of each other.
