So, you’ve flopped a straight or flush. This hasn't happened since Canute was a boy. Relax, for the first time in recent memory you can slowplay it, extract the maximum from the fish who have been swimming all the way to the river and sucking out on you there.
Wrong. Just as top pair is frequently beaten by an overlooked set, here the flop could be hiding seven outs to a full house – one to convert the set into quads and two apiece for the other board cards, just sitting there all innocuous, like, at the moment. You need to bet at least half the pot. And again on the turn because now there are ten outs, worse than facing a flush draw.
I’m talking to myself, of course. Myself of a few hours ago. Too late, again.
