Don't challenge!
If someone invite you to challenge, need to think - why? Maybe they want to want to place a bets, to entertain, and you will be just a toy in they game! Or may be someone want to resolve his problem, and you mind will try, you will tire, but challenger - will make a money and honor of wise-solver! (They will own your solution of problem, really?).
