May-08-09  arctic tern: <sleepyirv: Oddly, "Nuke Dukem Forever" was recently cancelled after a decade in development. Great pun!>

That should of course be "Duke Nukem". My first thought when I saw the pun: Hey, the CG staff are video game nerds!

May-08-09  patzer2: For the uninitiated in popular culture, who rely on google to catch up, here at is a discussion of "Duke Nukem."
May-08-09  patzer2: The desperado defensive move 23...e4! is interesting. One could call it a sacrifice, except for the fact that it is forced (i.e. the alternatives result in Black getting mated).

White does a good job of maintaining the advantage after 23...e4, but starts to slip with 27. Nd5. Instead 27. Rxf5! to retains winning chances.

White slips further with 28. h3 (better is 28. Kg1 ) and finally gets lost in a difficult position after 30. Rxf5? (holding for the draw by forcing a perpetual is 30. Qxf5!).

May-08-09  Kreifi: I think that this was the first pun ever I got without help. Sad. Very sad.
May-08-09  Eduardo Leon: I like Black's style. My style is similar. His precision is far greater than mine, though.

  sleepyirv: Apologies for the spoonerism, it's what I get for being up so late.
May-08-09  tivrfoa: Doesn't white has advantage after 24?
May-08-09  patzer2: <chessic eric>'s post from 2006 is correct in noting that 20...gxf5 plays out to a draw with precise play. However, it's not deserving of the (??) blunder designation as it may be the best move -- providing Black can see through the complications to the forced draw:

20...gxf5! 21. Bxf6+ Bxf6 22. Rxh7+ Kxh7 23. Bxf5+! (not 23. Qh3+?? Kg8 24. Bxf5 Rfd8 ) 23... Kh6! (not 23... Kh8?? 24. Qh3+ Bh4 25. Qxh4+ Kg7 26. Qg5+ Kh8 27. Qh6+ Kg8 28. Qh7#) 24. Qh3+ Kg5 25. Qg4+ Kh6 26. Qh3+ Kg5 27. Qg4+ Kh3 28. Qh3 (with a draw by perpetual).

May-08-09  DarthStapler: 3d realms just closed down, DNF did not finish
May-08-09  310metaltrader: is there as short win in the endgame
May-08-09  patzer2: The position after 21. Rxh5! (diagram)

presents Black with an amusing dilemma.

If he could run a long computer analysis, Black would find he is lost in all variations and could offer his resignation. Or since he's playing a human, he could figure out which move offers the most resistance and try for a swindle. Fortunately, for us, he choose the later course. Here's a few losing alternatives Black rejected:

(1) If 21...f6, White wins after 22. Rxh7+ Kxh7 (diagram)

(White to move and win after 21...f6 22. Rxh7+ Kxh7)

23. Bf4! exf4 (23...gxf5 24. Bxf5+ Kh8 25. Qh7#) 24. Rh5+ Kg7 25. Qxg6#.

(2) If 21... gxf5?? (diagram),

White wins after 22. Rxh7+ Kg8 (22... Kxh7 23. Bxf5+! Kh8 24. Qh4+ Kg7 25. Qh7#) 23. Bf6+! Kxh7 24. Qg7#.

P.S.: Great game! Thanks for the reminder that Chess is not only for near perfect moves played by computers, but also for us less than perfect humans. It is also a reminder not to surrender meedly in difficult near-lost positions, but instead to put up maximum resistance.

May-08-09  MikedaSnipe: ""Damn... I'm lookin' GOOD..!" That game rocked :-P!"

Dear god, I had a horrible father that let me play the 2d duke nukem when I was like 5-6. I just stood in front of the mirror and heard duke say that over and over.

May-08-09  Samagonka: What an exciting game! For a while, I thought white almost had it all. I still can't see where he went wrong.
May-08-09  patzer2: <Samagonka> With 27. Rxf5! (instead of 27. Nd5?), White is in no danger of losing and has strong winning chances.

With 30. Qxf5! (instead of 30. g3?), White can force a draw by perpetual.

Premium Chessgames Member
  ajk68: 30. Qxf5 is not an option. Black has given check on move 29.
May-08-09  MikedaSnipe: I'm a man that likes to exploit weaknesses, and I think 18... g6 weakens f6. Here's an idea - 19. Rh3 eying a mate/attack on the knight with Qh4. Expose the square to the f rook with fxg6/fxe6 if white allows, and just overall pound on the square.
May-08-09  patzer2: Correction to a previous post:

1) If 21...f6, White wins after 22. Rxh7+ Kxh7 (diagram)

click for larger view

(White to move and win after 21...f6 22. Rxh7+ Kxh7)

23. Bf4! exf4 (23...gxf5 24. Bxf5+ Kh8 <25. Qh4+ Kg7 26. Qh7#>) 24. Rh5+ Kg7 25. Qxg6#.

May-08-09  patzer2: <MikedaSnipe> Your 19. Rh3! looks strong and promising for White. One possibility is 19. Rh3! Kg7 20. Qh4 exf5 21. Bg5 to .
May-08-09  patzer2: <ajk68> You're right about <30. Qxf5> being an unplayable option. I meant to write 31. Qxf5! = forces the draw by perpetual.

Thanks for the correction!

P.S. There are now at least four potential improvements for White identified here, including 19. Rh3! to , 27. Rxf5! to , 28. Kg1 and 31. Qxf5! = forcing a draw.

May-08-09  MaczynskiPratten: 20 Rxf5 looks like some "Difficult" daily puzzles and when it gets to move 26 you almost expect the comment "and White wins simply on material after 27 Rxf5". It amazed me how fast the situation turned round as Black suddenly coordinated his two bishops and rooks together in just a couple of moves and exposed White's back rank weakness. I guess it amazed White too :-)
May-08-09  jepflast: Gotta love the Duke Nukem reference!
May-08-09  Alphastar: Duke Nukhim used his BFG on move 23.
May-08-09  patzer2: I need to revisit the 31. Qxf5! option. It's a best move, but there now appears to be one long and complicated maneuver by which Black can avoid the draw and go up a pawn in a Rook and Pawn endgame.

Based on a move-by-move look against Fritz, best play appears to be 31. Qxf5! Re2+ 32. Kg1 Re1+ 33. Kf2 (33. Kh2 Bxg3+ 34. Kg2 transposes) 33... Bxg3+ 34. Kg2 Bh4+! 35. Kh2 Re2+ 36. Kh1 Bxd5+! 37. Qxd5 Re1+ 38. Kh2 Rd8! 39. Qg2 Bg3+! 40. Kxg3 (40. Qxg3 Rd2+ 41. Qg2 Rxg2+ transposes) 40... Rg8+ 41. Kh2 Rxg2+ 42. Kxg2 Re2+ 43. Kg3 Rxc2 44. Rd5 Rxb2 45. a4 Rb4 .

Perhaps someone with a table base program handy can advise whether the ending is a win or draw for Black with best play.

Either way, it appears that 31. Qxf5! is White's's best chance to avoid immediate lost, even though he will have to fight for the draw in a pawn down ending.

May-09-09  kevin86: Is this one unique? In turn each side gives up the queen to save the game. Black's intermezzo-his 32nd move- however,gains him an extra piece and soon the game!
Apr-25-18  Straclonoor: Rook sacrifice 20.Rxf5 gives only draw.
