  chancho: It's not every day you see FM Curdo getting pulvarized in 19 moves.
Feb-15-12  bwarnock: I've got one like this against Ivanov (not quite as devastating, but almost) - I'll see if I can dig it up....


Feb-16-12  bwarnock: I was experimenting with different ideas in Alekhine's defense but to no avail here:

Queen City Open, Manchester, NH 2/18/89

A Ivanov - B Warnock
1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 c6 5.c4 Nc7 6.Be3 Bg4 7.Qb3 Qc8 8.Nbd2 e6 9.exd6 Bxd6 10.Ne5 Bf5 11.g4 Bg6 12.Bg2 Bxe5 13.dxe5 Nd7 14.f4 Na6 15.Qa3 h5

Here I was expecting 16.h3 when I figured White would be somewhat better after 16... hxg4 17. hxg4 Rxh1+ 18.Bxh1 c5 followed by Qc7 and O-O-O ... instead watch what happens:

16.f5! exf5 17.gxf5 Bxf5 18.O-O! Nb6 (??)

(bad - but Black's in trouble anyway - 18... g6 is tougher)

19.c5 Nd5 20.Nc4

White's winning a piece (!)

20.... O-O 21.Nd6 Qe6 22.Rxf5 1-0


May-20-14  zanzibar: A little interesting that 9.c4, which really doesn't seem to help White all that much allows the bishop to maneuver over for the win at the end.

Black should have played 9...Nxd4 both simplifying and allowing the e7-knight to get to to c6. Or 9...g6 planning to fianchetto, or even 9...Ne5.

But Black squandering some good tempos putting the knight on g6 then h4, not such a good idea. Not with the king in the center.

That's my take on it anyways.

Jul-04-14  RookFile: 5....Bg4 was odd from Curdo, nobody knew better than him that Bd7 was more solid. Then, he surely considered 8....Nxd4 trying to get a couple of minors off the board, albeit at the cost of centralizing white's queen. I guess he wasn't in the mood for getting ground down by Ivanov's endgame technique - but of course, the grandmaster was more than up to the challenge of how to play a lethal middlegame.

  perfidious: What <RookFile> states is reasonable regarding Black's fifth move, so far as I know--I am sure though that in the more than two years since Ivanov had lived in Massachusetts when this game was played, he and Curdo had already met numerous times and it would not surprise me at all if John has already tried 5....Bd7.
Jul-04-14  zanzibar: I suppose if 5...Bg4 then after 6.h3 Bxf3 would be more "natural" (or even 6...Bh5). Otherwise 5...Bd7 straight-away.

I was wondering if 7.d4 before c3 was too aggressive.

Maybe not:

7.d4 b5 8.Bb3 Nxd4 9.Nxd4 exd4 10.c3
( 10.Qxd4? c5 11.Qd5 c4 ) 10...dxc3 11.Qh5 Qf6 12.Nxc3 c6 13.Re1 Qg6 14.Qf3 Qf6 15.Qe3 Be7 16.e5

White sacks a pawn for lead in development and tries to catch Black's king in the center - reminds me a little of Smith-Morra (well, maybe not).

Jul-04-14  zanzibar: (The power of the e-file)
Apr-23-16  happyjuggler0: Perhaps Curdo had planned to play 6 h5 but accidently touched his bishop by reflex? For an example of that move, see:

J Peters vs J A Curdo, 1970
