Again, I'm just saying that the premise in the OP saying to 'bet once then nothing' sets the noobs the wrong idea about EV. Sure it's the right spot to take but then what? What if the bet loses? What's the explanation that it was the right spot to take... Where's the realizing EV part?
Ok.. Maybe I jumped the gun too fast by saying the premise is wrong. It's more like it's incomplete. As you may already know, EV is only realized over a large sample. So yeah..
No worries. I do understand where you're coming from. It's just that EV have a different weight depending on circumstances: for a set up when you have unlimited bet attempts and unlimited bankroll - you'd be happy to go for it even if the EV was +0.000001 because you're guaranteed to make a profit (excluding the time factor). But for one-time event, or even for situation when you have limited bankroll and can only place X number of bets - that's where things get complicated, and that's what this thread is about.
