"Equity in the pot"? Quess I'm kinda dumb. The pot is the "pot", my chips are "my chips". Once "my chips" go into the "pot", they then belong to the "pot". Equity = value, the pot has that, but I do not gain or lose any value (equity) of my chips just because I had previously put chips into the pot.

Does this mean that if you enter any chips into a pot, your "equity", more or less makes you pot committed? Man, I just look at the pot, look at my cards, & decide if I have the odds to win it.
In this situation, bottom set, I would consider my odds of winning the hand as "very good". Therefore, I'm in!
