right, so you know you're supposed to dribble, but the poker player doesn't know they are not supposed to string bet (they didn't know what string betting was).. yep, still apples an oranges.
The relative fundamental aspects don't add up. You're analogy is no good (plus the stakes are way off)..
Dribbling is to basketball as string betting is to poker?
I disagree with that logical fallacy... so you run your game your way and I'll run mine my way.. sound good?
May be best to ignore my "poor" example and address the OP directly if you have more to add.
First, it would be betting is to poker as dribbling is to basketball (both pretty important aspects of their games) and string betting is to poker as palming the ball while dribbling is to basketball (both subsets of the original but still quite important). That pretty much looks like apples to apples to me.
Second, you kind of ignored the whole premise that the rule you quoted doesn’t apply to the situation you presented. Basically, there is no rule that allows the string bet to be acceptable. While I understand why you may be inclined to allow it, as others (and I) have mentioned, not consistently following rules leads to problems. What are you going to do when the next player string bets? Where do you draw the line? What do you do when the next “new-to-your-game” player string bets and it looks like he may have been shooting an angle, but you’re not sure? Again, I understand the inclination, but it really presents problems to not apply the standard rules consistently.
Third, of course, you are well within your rights to run the game as you see fit and I hope you and your players enjoy it. I’m fact, I hope you all enjoy it for a long time. That brings me back to the original point. The friendlier the game, the more important it is to enforce the rules consistently if you want to keep it friendly. Best of luck.
