Question about not using "Check" in Actions

[mervai]

Hi fedden / big-c,

Thanks for the continued updates. I've been reading through the code again and noticed there isn't an action for "Check" (Pass). Is this to reduce state/action space or is it implemented via one of the other actions i.e. "Raise zero" / "Call zero"? Otherwise, I imagine the agent would end up playing a bit more aggressively than game theory optimal.

Edit: i'm quite sure its the latter now, raise zero / call zero. The dummy amounts > 0 for AbstractedRaise threw me off, but AbstractedRaise isn't used anywhere.
