Listen, this has nothing to do with being on a high horse or throwing you under the bus. I'm trying to help you and make a point. Yes I have been wrong before and I learned the hard way about this, I'm trying to help you so you learn the easy way (on a forum and not on the course) Years ago I thought I knew the rules. I read the rule book many times over and didn't even know a decision book existed. I, in all my wisdom insisted to a playing partner on a rule. I was wrong and by my being wrong it cost him a tournament. I then went home felt bad about (still do) and re-read the rules book, found about the decision book- read that a thousand times and signed up for about 5 USGA rules seminars. I now have a fairly decent grasp of the rules yet still know when to zip it if I'm not 100% certain on the rule.
My point about your post is that you posted it as fact. In fact here is your first line "Nope, as soon as you put down that 2nd ball, that ball is in play." You sound pretty darn sure of yourself in that line. You even cut and pasted rules etc... Even though you had two guys post ahead of you with the correct ruling. When it comes to the rules of golf there are no opinions. It's all fact. Either you know the rule or you don't. and my point is if you don't or are unsure it is wise to say you are not sure and take it up with the committee. In stroke play you have the option to play another ball but in match play the call has to be made right then and there, even if you can't get a committe member out quick enough to help.
If a person is asking a rules quesiton on this forum or any other one, it does him no good to have people answering with opinions or "i think" or I assume".......or worse guys answering as fact when in fact they are wrong. If you know for a fact the answer then post it. If you don't then don't even bother to respond with the ruling, b.c it does them or nobody else any good.
My point was not to try and throw you under the bus but to help you and others by my mistakes. It's a bad feeling to give someone a ruling because you think you know the rules well only to find out you were wrong. And I'm sorry to say you would be arguing with anybody, I don't know that to be a fact. I guess what I do know in that situation, according to your post, you would have at least been trying to say the second ball is the one in play and the score that counts. My appologies for being to blunt, rude, direct etc... didn't mean it that way.
