Default Chess Puzzles - August 15th

Here are some puzzles taken from the chess games of strong players of
the early 20th century. Except where noted, it's "White to Move and
Win".

Another solution is 1. Re8! The main threat is 2. Qxf7 with
unavoidable mate, the scondary threat is 2. Rcxc8. Black is forced to
take the rook, where follows 1...Rxe8 2. Qxf7 Qf8 or Qg6 (2...Nf6 3.
Bxf6 gxf6 4. Qxe8+ Kg7 5. Qf7+ Kh6 6. Rc7 (threat Qxh7+ and Rg7 mate)
6...Qxc7 7. Qxc7 +-) 3. Bxg7+ Qxg7 4. Qxe8+ Nf8 (4...Qf8 5. Rxc8
(threat Qxd7) Rd6 (5...Qxe8 6. Rxe8+ Kg7 7. Re7+) 6. Qxf8+ Nxf8 7.
Rxf8+ Kg7 8. Rf5 +-) 5. Rxc8 Rf6 6. Qe5! Black can't move a piece and
White threatens Rc7.
