The "Please Don't Call Me" raise on the river
I've noticed a frequent pattern where someone will throw in a large raise on the river. Instinct often tells
me they've been raising in the hope of landing a straight or a flush and it hasn't landed and they've got nothing or a low pair and the big raise is about scaring off a call.
Obviously sometimes it's a strong hand but I'm sure it's often just a scare tactic. I would like to call these more often than I do. How do you, if you do, differentiate between the bluff and the genuine strong hand?
