Jul-07-05  Knight13: I don't understand 23... Rxf3, man. It looks like a fatal sacrifice. Is it forced?

50... Kf7 51. Rf5 Ke6 52. Rxf4 and White wins or 50... Bg5 51. Kg4! Bh6 52. Kxh4 Kf7 52. Kg4! and Black loses the f4 pawn and White wins eventually.

Jul-07-05  sneaky pete: <Knight13> Hey man, like, do you mean 60... Kf7 and 60... Bg5? Like, man, with the black King on f5 your move 50... Kf7 is impossible, as is 50... Bg5 with, like, a black pawn on g5.
Jul-07-05  Knight13: <sneaky pete> Yeah, man. 60... Bg5 and 60... Kf7, man. Sorry about the mix up.

I hear ya, dude. But White is threatening 24. Ne5, forking queen and rook. Since Black is all, whoah, there goes the exchange, it's like he might as well break up White's kingside pawn structure. So 23...Rxf3 totally makes sense.

By the way, recently your posts are full of American teenager dialect. Did you pick this up from your classmates? The other posters on this forum are getting all weird about it ;-)

Sep-13-06  sneaky pete: 23... Rxf3 isn't forced, he could have played 23... Nf4 and if 24.Ne5 Nc4.

MacDonnell is white in this game according to Bachmann, but La Stratégie (source of the Oxford Encyclopedia) published the game in 1872 with De La Bourdonnais playing white. This may be right, because of the move order by which the normal position of the Evans Gambit is reached here. In his other games as black De La Bourdonnais played 6... Bb6 7.d4 exd4 8.cxd4 d6, while MacDonnell preferred 6... d6 7.d4 exd4 8.cxd4 Bb6 as played in this game. Another point to support this supposition: to furiously counterattack in the middle game when, as black, he is expected to defend, is typical of the Big Mac's style.

Feb-01-12  Knight13: If nothing else, I applaud White's endgame technique here. Splendid.
