Lighter.. "The action you need to take in the second round is to choose a door."

Yup. And there are two doors available. ONE choice between TWO doors (options). The fact that there were three doors at the start simply cannot influence ONE choice between TWO options in the second round.

If you stick, that is choosing one option. If you switch, that is choosing the other option. Basic, nitty-gritty of philosophy... the base of all human analyses of logical thought... A OR B. Positive or negative. Night or day.

Where the arguements proffered fail MY logic is that they fail to equate switching and sticking as ONE choice between TWO options.

Oh... re me having a go? Having "fun" by sticking to my arguement... Nope, not a hope. I am quite serious. And, until someone shows me "different", I will stick. When anyone can prove me wrong, I shall buy them a pint and apologize profusely.

Then again, I bought a Looto Max (yes, typo intended) ticket today for the $40M prize tonight and that is quite illogical. >;-)
