Same rules: pick at least 1, whoever picks last one wins..... I say: Ok Albert, YOU start... OK, make your pick, and post result; like, if you take 4 from B2, then post: I took 4 from B2: B1 3 B2 4 B3 11 I'll then pick, and post similarly....OK?!

Well, I don't feel like solving this for another two hours , since we all know the strategy, let's just watch for fun: *To The Crowd" "Ladies and Gentlemen, welcome to today's game play of 'picking marbles from boxes', this match will be between Denis and Albert, two great mathematicians of The MMF. The prize to the winner of this match, uhh... Be all the imaginary marbles and boxes! The start position is: 3 marbles in box 1, 8 marbles in box 2, and 11 marbles in box 3 Denis, being a great gentlemen, gives Albert the first pick. Is Albert going to take his advantage and win this game? Or is Denis going to win against all odds? Stayed tuned!"

Yes, rules were the same, EXCEPT the "whoever picks first wins";
in this case, whoever picked first (YOU) loses; I was kinda having fun.
I sent:
0011 : 3
1000 : 8
1011 : 11
=====
2022 : so I was sure of winning by letting you start

What you do is let them win the first game (lose on purpose) because otherwise they will get bored.
Then you win every game, but they will continue playing (most likely) because they won the first game and will not think you know the strategy, until you win six or seven games in a row

And I think this is a good way to use 10 minutes of your life

Also, play a game of starting position being 21,27,32, I don't know who wins, but I think this strategy might not work for the first few moves

Sure it'll work right away...and you start to win:
SETUP:
010101 : 21 (B1)
011011 : 27 (B2)
100000 : 32 (B3)
=======
121112

You take 18 from B3:
010101 : 21 (B1)
011011 : 27 (B2)
001110 : 14 (B3)
=======
022222 : so now you're sure to win!

(hope Albert is proud of me!)
