vs a competent opponent im never folding there -_-

and with 99 its a mathematical call even if one guy has a straight

can some1 explain the maths? would help alot

so hand1 was badly played by me and hand 2 was a bad beat

anyway i stacked that donkey in hand 2 soon after so the world is all butterflies and bees again

he said equity on the turn, not river

ok turn then, my bad. its hard to believe its mathematically correct to call that turn when 2 players have already called the all in on the 4 card str brd before me. someone show me the maths please!
