1. ## Ultimate Mate

Thanks, TSLF. I don't see how Black can get stalemate in that sequence. I could not find the 9-move variation. my blunder, Kg4 yes, the black king is just there for the play , i guess any solution can give continuous checks to ensure checkmate.

3. ## Ultimate Mate

A sufficient condition for White to win is to attack every square. If such a White position exists, get there in a minimum number of moves. Since Black has access to any/every square on each move

6. ## Ultimate Mate

Take all the black pieces except for the King and all the white pawns out of the board on initial position. From this position White makes regular chess moves. Black King can jump to any unattacked square. Black King is not allowed to capture White pieces. Check mate the Black King. This has a 9 moves solution but less than 20 will do.. __________________ Thanks to Prime for the assist

8. ## Chess puzzle

Ultimate Mate Take all the black pieces except for the King and all the white pawns out of the board on initial position. Now play White on regular moves, ask someone lift up the Black King and place it anywhere safe (e.i. unoccupied or unattacked squares) including its previous position. Lets see how long will it take for you to capture the flying King.. This has a 9 moves solution but less than 20 will do..
