Sorry, I don't need to dance. Read the OP for rules. I'm glad you're interested, use an escrow if you feel a risk of losing your coins.
Yes you do, we all on the same dancing floor. And why should I use an escrow to make a bet with you? I don't trust anyone.
I'm just asking politely you prove that you own the coins set as maximum bet, by your own words in OP, so I can trust you and make my bet.
I will bet you 100 Bitcoins that Matthew will fulfill his end of the deal within 3 weeks after a conclusion.
This means that if Matthew wins (pirate pays out) Matthew is done and I get 100 Bitcoins from you.
If it is decided that Matthew loses and has to pay you his side of the bet with you, and he /doesn't/ do so within 3 weeks, I will give you 100 Bitcoins. (The 3 weeks start after it's been decided that Matthew loses. Suggestions on how this should be decided?)
