Chessmaster1000: And remember, as there are no checks in Extinction Chess, there are also no checkmates either. Hopefully you mean on the sixth move something of Black's is extinct, not that he has no way out of it and it will happen on the seventh move. Just asking for clarification.

Right nice puzzles you have here. I think I should give them a serious go if no one has claimed the prize by tomorrow. Time for bed now.
