What is the 'Bunching Effect' and how does it impact late-position opening ranges?

1. Folded hands in early position are disproportionately weak, making the remaining deck slightly richer in broadways.
2. It describes how ranges 'bunch' together at equilibrium, leading to many split pots.
3. It is the tendency for players to call more frequently when several players have already entered the pot.
4. It is the physical clustering of high cards in the dealer's shuffle, increasing the variance of the game.
