Picking up a tube in opponent's Safe Zone

[Jimmy K]

Keep in mind that it is only worth 36 points if you have 3 ubertubes in the top row on the same grid (which is very impractical), and even without that piece, you still would have 12 of those points. Of course, even without any ubertubes, that last piece would give you 12 more points than you had before. If you were already losing and taking the penalty was your only way to win the match, then it would be worth it (neglecting any Gracious Professionalism considerations).

This is sorta like fouling an opponent in basketball during the last minute. Your opponent gets a few more points, but you still increase your chances of winning the game.

I would consider it more "strategical" than "unsportsmanlike" as long as the foul isn't severe. You aren't damaging or destroying an opponent's robot, just stealing one of their game pieces (which isn't really "theirs" according to the rules).
