In heads-up play, can player A, who has 150 left, all-in if player B all-in at 100? Or he can only call?

Question

Player A has 150 left while player B has 100. Player B all-in first. Can player A all-in too of he can only call?

Answer 1

Both actions would result in the same outcome. If the lower stack is 100, neither player will put more than 100 chips into the pot.

Answer 2

are there more then two players, if only 2 players this question is mute there is no point putting all the chips. if there is another player that will need to cover the raise to proceed, then of course the player can go all, in
