1. It is the first hand, you have no reads.

YES, he has reads. He knows what the pool of players is
like at the beginning of MTTs, and knows there is a good
chance that, however risky, a play like this will rake
in a few hundred chips for him, which can be a
tremendous advantage, PROVIDING he doesn't continue this
LAG play.

2. It is the first hand. You have plenty of time to build your stack.

There is no time like the present. What would you pay
for a few hundred extra TCs at the beginning of an MTT?

3. It is the first hand. If you get pegged as a LAG and keep making these plays you will get caught sooner, rather than later, and blow the few chips you have just won.

If he gets pegged as a LAG early he can work it to his
advantage later--as long as he knows he's playing like
a LAG.

4. It is the first hand. You all have the same stack size. IF you already had a larger stack, reads on a tight medium-stacked player who you knew was capable of making a big lay-down -or- on a LAG you had a strong read on and were then sure he was bluffing, and had an image as a tight player yourself, THEN, this resteal might be considered a good play.

See number 1, above!

5. The fact that he/she folded is the only way you can justify your play. If "sadie" called and showed you a slow-played set of Tens, would you still insist it was a good play?

What is a good play if it is not one that has a
positive outcome?

6. It is the first hand. Risking your entire stack on a gutshot draw on hand 1 is not generally accepted Multi-Table Strategy.

Also see number 1, above. If people like the woman
who folded insist on contributing their funds to the
prize pools of MTTs they have no business playing in,
why should this NOT be "generally acceptable MTT
strategy?"

You are all reacting to this play like Menh the Magnificent did when he got busted by an Internet Player in the early goings of last year's WSOP. Ye who refuse to adapt...

Your play was not, to quote the title of your OP "stupid" until you consider the circumstances of when you made this move, which was, in most opinions, ill advised.
