A desperado is a piece that is going to be captured, so goes on the run, taking what it can down with it. White to play:
[Event "Desperado"]
[Site "Steven Carr"]
[Date "????.??.??"]
[Round "?"]
[White "NN"]
[Black "NN"]
[Result "*"]
[SetUp "1"]
[FEN "3r2k1/p4pp1/1p6/n5p1/2Pp2N1/2Q2PPP/P3q3/4R1K1 w - - 0 1"]
[PlyCount "3"]
{[#]} *
Black was hoping for 1. Rxe2 dxc3. But White thinks, if it's best to give up the Queen (to get Black's Queen), can I get more for it?
1.Qxa5! This is the desperado move: if I must die, I will take what I can!
Now 1... bxa5 2. Rxe2 leaves White a piece ahead. So, Black goes for checks and forks with 1... Qxf3 , but White covers the threats with 2. Qe5

1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. d4 exd4 5. Nxd4 Nxe4 6. Nxc6 {This frees the
Queen to move to e2, which pins and wins the Knight!} ({Black's idea is} 6.
Nxe4 Qe7 7. f3 d5 {, regaining the piece because of the pin} 8. Nxc6 bxc6 9.
Qe2 dxe4 10. Qxe4) 6... Nxc3 {Black's Knight grabs what it can before being
captured. This sets off an amazing series of captures by both Knights, who
greedily devour whatever they can.} 7. Nxd8 Nxd1 8. Nxf7 Nxf2 9. Nxh8 Nxh1 {
Whew! But it's not over yet...} 10. Bd3 Bc5 11. Bxh7 Nf2 12. Bf4 d6 13. Bg6+
Kf8 14. Bg3 Ng4 15. Nf7 Ne3 16. Kd2 Bf5 {It's all getting tense again!} 17. Ng5
$2 {White panics! This sets off another desperado...} Bxg6 18. Ne6+ Ke7 19.
Nxc5 Nxc2 $1 (19... dxc5 20. Kxe3 $11) 20. Bh4+ Ke8 21. Ne6 Kd7 22. Nf4 Nxa1
23. Nxg6 Re8 24. Bf2 (24. Kc1 Re4 25. Bg5 Rc4+ {rescues the Knight}) 24... Nc2
$1 25. Nf4 Nb4 0-1
The greedy Knights took made nearly all the captures in the game!
