Overtime bothers me in general as a salaried person. As an occasional 1-2 day push, it's understandable, but if they expect overtime frequently and/or for extended periods of time that's a management issue. Management has failed to schedule work appropriate or staff appropriately.

With poker the opportunity cost of my spare time is more easily quantifiable (about $30/hour right now), but whether I wanted to play poker with that time or not, it's still has value.

I do agree though that poker really dimishes any drive to crank work for some bonus. The bonus is never as good as what I make from poker, so all things equal, I'd rather skip the work bonus and play poker.
