Pierce Gambit Fails, f-Pawn Delivers Mate

     Englishman William T. Pierce (March 30, 1839 – May, 1922, 83 years old) was the younger brother of James Pierce, the weekly chess column editor of the Brighton Guardian and English Mechanic. The Pierce Gambit in the Vienna Game (1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.Nf3 g5 5.d4) is named for him. 
     The following game was played at the Manhattan Chess Club way back in 1897 between Louis Schmidt and E.A. Orchard and it features a failed Pierce Gambit and a masterful attack by black that ends with an unusual mate delivered by his f-Pawn.
     When I first played through it, things looked pretty straightforward. White played the discredited Pierce Gambit, got nothing for it and black annihilated him. As ypou will see, things weren’t quite so simple. 

A game that I liked (Fritz 17)

[Event "Manhattan Chess Club"] [Site "?"] [Date "1897.??.??"] [Round "?"] [White "Louis Schmidt"] [Black "E.A. Orchard"] [Result "0-1"] [ECO "C25"] [Annotator "Stockfish 16"] [PlyCount "54"] [EventDate "1897.??.??"] {Vienna Game: Pierce Gambit} 1. e4 e5 2. Nc3 {The original idea was to play a delayed King's Gambit, but in modern play white often plays more quietly. At on time Weaver W. Adams claimed that the Vienna led to a forced win, but it actually leads to no more than equality.} Nc6 3. f4 exf4 4. Nf3 {Steinitz once declared that in all gambits (with the exception of his own, i.e. 4.d4) that 4. Nc3 is decidedly in favor of black.} (4. d4 {The Steinitz Gambit was a favorite of Wilhelm Steinitz. Black is allowed to misplace white's K with 4... Qh4+ 5.Ke2 with the hope of proving that white's P-center and the exposed position of black's Q are more significant factors. Unlike Steinitz, few modern players are willing to expose their K in this fashion.} Qh4+ 5. Ke2 b6 6. Nb5 {with an interesting position where black can try a number of moves, but 6. ..Ba6 or even 6...Kd8 are the most promising.}) 4... g5 {[%mdl 32]} 5. d4 {At the time this game was played the English player William Pierce had published analysis on this move demonstrating that white has good attacking chances and so it came to be known as the Pierce Gambit. While practically speaking that may be the case, engine chalk it up as just losing a P.} g4 { The unambitious 5...d6 only results in equality and so justifies white's play.} 6. Bc4 {The logical followup.} (6. Ne5 {is not quite as good because after} Qh4+ 7. Ke2 d6 8. Nxc6 g3 {black has a strong attack. White is forced to move his K again to avoid ...Bg5+ and so blocks his other B.} 9. Kd2 bxc6 {White's prospects are looking quite grim.}) 6... gxf3 7. O-O {After this white is practically lost.7.Qxf3 was a little better.} (7. Qxf3 Qh4+ 8. g3 Nxd4 9. Qf2 Qf6 10. Bxf4 {White's position has little promise.} Bb4) 7... d5 {At the time this is considered black's best move, but is actually allows white to equalize. } (7... Bg7 {This leaves white virtually helpless.} 8. Qxf3 Bxd4+ 9. Kh1 Ne5 10. Qxf4 Qf6 11. Nd5 Qxf4 12. Bxf4 Nxc4 13. Nxc7+ Kd8 14. Nxa8 Be5 {Black has a decisive advantage and in Tomazini,Z (2038)-Crepan,M (2317) Porec 2008 he went on to win.}) (7... Nxd4 8. Qxd4 {A blunder that loses immediately. Best was 8.Bxf4, but black would still be better.} Qg5 {The threats are ...Qxg2# and ...Bc5 so in the game H.G. Voigt-Charles Devide, Philadelphia, 1897 white resigned. His best line would have been} 9. Rf2 Bc5 10. Bxf4 Qxg2+ 11. Rxg2 Bxd4+ 12. Rf2 {but it's quite hopeless.}) 8. exd5 {Thanks to black's slip white has now equalized.} Bg4 9. Re1+ (9. Qd2 {is only equal, but it worked out well for white in this game...} Na5 10. Bb5+ c6 11. Qxf4 Qd7 {Correct was 11...cxb5 with equal chances.} 12. Qe5+ Ne7 {A huge mistake! 12...Be7 would have at least kept him in the game.} 13. Ne4 {After this there is no way for black to sacve the game.} O-O-O 14. Bf4 {Black resigned. David,A (2380)-Pinter, J (2580) France 1993}) 9... Nce7 10. gxf3 {This lets his opponent regain the advantage.} (10. Bb5+ Bd7 11. Qxf3 Bxb5 12. Nxb5 a6 13. Nxc7+ Qxc7 14. Bxf4 { AT this point black's advantage is minimal.}) 10... Bd7 (10... Bh3 {is a bit more precise.} 11. Bxf4 Nf6 12. Bb5+ Bd7) 11. Bxf4 Bh6 {The position noiw enters a phase of huge complications!} 12. Bg3 {More precise would have been 12.Be5 first because it would have forced black to play 12...f6 depriving his pieces of f6.} Nf6 {Also good would have been 12...Kf8 so as to play ...Nf5} 13. d6 {Aggressive play, but countering with 13.Qe2 would have been more efficient.} (13. Qe2 Rg8 14. Qe5 Rg6 15. Bd3 Kf8 16. Bxg6 Nxg6 17. Qxc7 Qxc7 18. Bxc7 {In this unbalanced materiual situation (R+3Ps vs B+N) theoretically black is better, but practical play is a different matter.}) 13... cxd6 14. Bxd6 Rg8+ {It's difficult to pass up this juicy check,m but it does no more than equalize!} (14... Be6 {This wimpy looking retreat maintains a clear advantage because it leaves white with no followup.} 15. Bc5 {Best.} O-O (15... Bxc4 16. Bxe7 Qxe7 {A sad necessity!} (16... Qd7 17. Bxf6+ Kf8 18. Bxh8 { and white wins.}) 17. Rxe7+ Kxe7 {Theoretically this position favors white, but practically it's unclear.})) 15. Kf2 {[%mdl 8192] Of course white does not to place his K in the corner on h1, but that is precisely where it belongs in order to be safe!} (15. Kh1 {and White stays safe.} Bh3 16. Bxe7 (16. Rxe7+ Qxe7 17. Bb5+ Nd7 {There is a cunning trap here!} 18. Bg3 (18. Bxe7 Bg2+ 19. Kg1 Be3#) 18... Kf8 {Black has a decisive advantage...he's a R up.}) 16... Bg2+ 17. Kg1 Bh3+ 18. Kh1 Bg2+ 19. Kg1 Bh3+ 20. Kh1 Bg2+ {Draw by 3–fold repetition.}) 15... Bh3 {There are complications galore!} 16. Bg3 (16. Rxe7+ Qxe7 17. Bb5+ (17. Bxe7 Rg2+ 18. Ke1 Rg1+ 19. Kf2 Rg2+ 20. Ke1 Rg1+ 21. Kf2 Rxd1 22.

Bb3 Bf4 {[%mdl 512] A master stroke as will be seen.} 20. Bxf4 {Very risky, but black already has gained a winning position.} (20. Rg1 { turns out to be equally hopeless.} Bf5 21. Qe2 Nfd5 22.
