I don't understand how anyone could think the OP is a d-bag, considering he was following the rules.
This ain't tiddlywinks, people. If there's a reward at the end of the line, whether it be cash, tournament winnings or a plaque.....you play by the rules.
If you want to suspend the rules in some situations, then you need to play strictly for fun amongst friends or in a recreational league with the only reward being that you feel all fuzzy inside after a nice day at the pool hall.
What happens if you suspend the rules and say, "Yea, it was 3 and you didn't warn me on 2. But, since you did such a great job of locking me up, well, I concede that rack." Because THAT is what you would be doing. You're going against the written rule and you're conceding. Would you do this in a Calcutta event, when you have people that may be wagering that you will win the set? What if someone bought you in the Calcutta? Wanna explain to them that your conscience wouldn't allow you to follow the rules and you conceded a game because it would be difficult to sleep that night? Because, if their money is in your saddlebag.....ya better believe they're watching your match.
What if it's simply a league tournament? Well, if you concede that game.....there's no going back. You've lost. The "future" has been altered. What happens if you then go on to lose the match? You've now affected the bracket. So, someone else who followed the rules to the letter now has to face a different opponent. Perhaps it's an opponent that they don't match up as well against. And then THEY lose. And so on and so forth.
Rules are there for a reason. Without them, there would be Old Testament kinda stuff. Fire and brimstone. Cats and dogs living together. MASS HYSTERIA.

Again......there is no room for your conscience in the game of pool.
