I have played in two live tournaments when I was under 21. First was the LA Poker Classic $1K WPT event in which I was assured they would pay me in chips and not give me any tax forms. I lost a coinflip on the bubble anyway.

The second was more interesting. It was a $100 buy-in at one of the Colorado casinos. They were giving out tax forms if I finished in top 5. I was mostly playing tight and just messing around during it. At the time, I felt like $100 was just garbage and it was worth it to improve my live MTT skill. I start getting close to the final table and realize I have a VERY large stack. I didn't want to deal with my fake ID and make a fake social if necesary or go through all the BS so I decided to take a dive. Here is where the fun started.

Just before we left for the casino, I had taken Exctasy for the first (and only) time. I brought pot with me and smoked up while I was there. When I found out how close I was to winning this thing, I added drinking heavily into the mix. I got an image going where they believed I was just piss drunk and going all-in preflop every hand for fun. In fact, I was going all-in preflop every hand, but it was to get out. First time I get called by something like AK short stacked where I have J4. Now they really think I am nuts and when I send the AK to the rail, they go nuts (You know how stupid people are). Anyway, next all-in got called in two spots by one large and one average stack so I was finally happy. I turn over my blind 96s and they both have AK. Flop is A96 and with no help, I take both of them out and suddenly have almost 1/3 of the chips left in play! After two more knockout blows I have 1/2 of the chips left in play with 8 left and 4 to go before I needed to exit.

I got a 10 minute penalty for swearing when I won the last pot which could have been really bad. Everyone left was so short on chips and I didn't want to come back to a final 4 or 5. BTW, I swore because I won the pot and didn't want it, but it was like my 8th KO in a row.

During my 10 minute hiatus, I decide to think over a new plan. My friends told me to just go for the win, but I was all paranoid and on drugs so I wanted to just get out of the situation. I decided a better plan of action would be to just bet and call off almost all my chips and then fold to whatever they have left when it is a small amount or go all-in once I'm sure I am going to lose. This worked well and with the help of some extra bad luck, worked really fast. I was the next to go and finished 7th place. Scary night.

EDIT: I shouldn't say only two, now that I think about it, more like 5-6, but others were smaller and for learning purposes.
