      Hi Martin
      Do you not think that the line given by you and
      continued by me (see below) is worse for White who
      is at the end a pawn down?
      Kurt

r1b2bnr/ppp2k2/1q5p/3P4/3Q1p1P/6p1/PPP1N1P1/R1B2BKR w - - 0 14

[Event "Kuba-ch"]
[Site "Havana"]
[Date "1900.??.??"]
[Round "8"]
[White "Corzo y Principe, Jua"]
[Black "Capablanca, Jose"]
[Result "0-1"]
[ECO "C25"]
[SetUp "1"]
[FEN "r1b2bnr/ppp2k2/1q5p/3P4/3Q1p1P/6p1/PPP1N1P1/R1B2BKR w - - 0 14"]
[PlyCount "14"]
[EventDate "1900.??.??"]

14. b4 Bxb4 15. Be3 Nf6 16. Qxf4 Bc5 17. Bxc5 Qxc5+ 18. Qd4 Qxd4+ 19. Nxd4 Nxd5
20. Bc4 c6 0-1

And in this line, White is a pawn down.
