3 betting light has nothing to do with your bet amounts it has to do with the cards you hold, means to 3 bet someone with a medium strength hand like KQ or KJ.
Matter of semantics, but stormy is correct. This is a concept that short-stackers will try to use to their advantage. If you have a short stack, people will "call you down light" meaning they will call with less strong
hands because the risk to their own stack is less. If done correctly, you'll get your money in a lot of times at 60/40 or better. Someone ( looks at Storm..., should post a strategy article about short stack play)..
On the first hand, if you were willing to put another $14 or whatever in the pot when he bet (then you raised him all in), why didn't you just put him all in on the flop?
I watched the whole video, no offense to some of the previous videos, but this one has several difficult decisions that make for good discussions.
