Loved the last two apples and oranges mix of videos by HC and Ttwist.

HC – One tp and op situation that I read about in Ed Miller, Flyn, and Metha's book, Professional No-Limit Hold-Em Vol.1

regards stack to pot ratio – when holding tptk you have that pre-determined number of let's say 4 x the size of the pot pre vs

a standard or unknown player and 6 x the size of the pot pre vs someone you know is bad. And with an op hand to the board,

you can make it 6x and 8x.

So if the pre-flop amt of the pot gets to be bigger than the predetermined number, with lets's say a ch/call to your c-bet on the flop,

and a c/r on the turn, you will fold because it keeps you from losing two or three hundred bbs with just a pair.

Do you ever use this concept?

I hope I was clear enough, maybe someone else could describe the concept better than I.
