Player 3 can call player 1's all in ($60 more) or fold. He can't raise because the $100 all-in is a $20 reraise - less than the minimum bet at this point of $40.

If it were an $85 all in his options would be calling $45 or folding.

But I'm sure I missed the loaded part of this question. Does Play 3 only have $45 more to start with?
