First: 1. Qc5+; Ka4 (forced) 2. Qa5#
Second: 1. Qxf7+; Rxf7 (If Kh8; 2.Qxf8#) 2. Re8+; Rf8 (forced) 3. Rxf8+; Kxf8 (forced) 4. Re8#
Third: 1. Qe6+! ... 2. Qc4#/Qd5 depending on the opponent's move.
And the site's puzzle:
1. Kc2; b3; 2. Kxc3; Ka3; 3. Rb1 zungzwang
On the third puzzle from pcfilho, 1. Qe6 is defended by 1...Nc3. I believe the key move is 1. Rg4.
1. Qe6; If Nc3; 2. Qc4#
1. Qe6 Nc3 2. Qc4+ Kxe5

In fact, the last move, Rb1, by the white is not mandatory. He can proceed with other pawns on the right side of the board.
The basic reason behind 3. Rb1 is white needs to go to b1 in order to win because white needs to stop the b2 pawn from moving and freeing the b2 square for the b3 pawn. And if 3. Rb1 a1Q then 4. Rxa1+ bxa1Q 5. Rxa1#.
no checkmate but after the pawn takes the rook, the other rook blocks off the other pawns from advancing. Good One!
