on most flops that come like that (K-Q-10), or most flops period, if there is a lot of action, (i.e. bet, raise, reraise; or even just bet, raise,) depending on the type of players they are, i throw it away. most people aren't raising, and especially not REraising, without at least 2 pair. I cant figure i'm a favorite anymore, and by this point i've worked up enough discipline to be able to throw them away. just toss 'em and smile when you know you would have lost
