We are implementing a poker client UI, and unsure about how to show the call or raise amounts in the action buttons so that it does not cause any confusion. I'm not a player so sorry if the terminology used is wrong.
Let's say player A opened the betting with $10. Then player B raised it to $50. On Player A's turn, If the call button shows $40, does that unambiguously mean the total bet will be $50 because he already has $10 bet in front of him? Or is it better to show it as $10 + $40? What is the norm here?
Similarly, does the amount in raise button in common poker room software mean the minimum bet will be raised "by" or "to" the amount specified?
