Comparing Main Pots and Side Pots in “All Ins”

For some time now, there’s an issue that keeps on hunting me. Well, it has something to do with comparing main pots and side pots in “all ins”.

For an instance, there are four players involved in a certain event, naming player 1, player 2, player 3, and player 4. Player 1 goes all in with $50, player 2 matches the all in, player 3 also matches the all in, and player 4 folds. Say player 3 wants to raise a side pot with player 2, do you think player 2 have to match the side pot or just fold? Any idea?

Please help me.

Sean,

In the scenario above, if player 3 bets or raises, then player 2 must call the bet or fold. If player 2 folds, they forfeit their rights to the main pot.
