Kibitzer's Corner
Aug-02-04  Knight13: Black must give up the rook? I don't know.
Oct-05-04  morphy234: if he doesn't give it up, then e8=Q#
Nov-02-04  Knight13: I never knew Mahe would try such a opening that Henry Bird played. Normally, people would answer 4. c3.
Oct-27-05  who: Did they have e.p. back then? I would assume not, as otherwise the final move seems awkward. Not that white isn't winning anyway, but after bxa3 e.p. it's more uncomfterable for white. Far simpler would be 55.Rxb4 Kxe7 and white has many ways to win easily.
Oct-27-05  who: 26...Rxe6 would be a beautiful tactical shot as after 27...Bxd5 28.Qxd5 Qxh2#
Feb-06-06  Boomie: <who> 26...Rxe6 is crushing. Nice find.
Apr-22-06  Gypsy: <who: 26...Rxe6 would be a beautiful tactical shot> Very nice find.
Dec-22-06  Themofro: Nice find indeed.
Dec-18-07  nimh: Rybka 2.3.1 mp, AMD X2 2.01GHz, 10 min per move, threshold 0.33.

Mar-08-08  popyseed: on 41 black Bc6 and he gets another chance
Mar-08-08  InspiredByMorphy: <popyseed> 41. ...Bc6 42.Rc3
Mar-09-08  sneaky pete: Or 42.Rd8+ ..
Feb-01-12  Knight13: <Morphy on 2. d4: This is not to be commended. In this opening White ought not prematurely to advance his queen's pawn, as many positions may arise when it will become necessary to place it at d3.> Little did Morphy know that in 2001, Ernest F Pecci would smash Fritz 6 with the same move that La Bourdonnais used here.
Jun-16-15  MindCtrol9: <who, boomie> I don't see anything:If <26...Rxe6 27. Rxe6 Bxd5 28.Rf3> Black has 5 pawns vs 4 White, but the endgame would not be any easy for Black to materialize the extra pawn.I could even risk to say that I like White position to play it out.
Jun-17-15  morfishine: <MindCtrol9> After 28.Rf3, Black can continue <28...Rc8> When White is hard pressed to counter the rook invasion. For example, if 29.Re1 then 29...Be5 and White is getting overloaded: something has to give
