I've been playing Czech Checkers since I was a kid and the Queen had always precedence as to jumping the opponents pieces. If you have a possibility to jump with your Queen, you have to do so. Period. That's the rule. And that's how it's been played here for decades, at least. If you have problems with this rule, there's one simple solution for you: don't play this variant. Plus it is very sick to demand a draw and put your opponent on your enemies list just because he follows the rules. In case you want to play any game on this site, I recommend to read the rules first.
