Some Bogie games here ...

It mentions that the position was from one of his correspondence games, but you'd have he'd have spotted the incorrect knight/bishop.
  

Those who want to go by my perverse footsteps play such pawn structure with fuzzy atypical still strategic orientations

It may interest some here to know that if you look carefully, you'll see that a Nb5 classical is being analysed by Rick (Humphey Bogart's character) in the chess scene in Casablanca.  Rick, sitting on the black side, picks up the night and toys with putting it on b5.  I think this was metaphoric on Bogart's part: an unsound attack against the French, likely to redound on the attacker.

For some reason though, he had Black's QN and QB reversed.

It could be that 9...a6 is actually best; then on 10. Nd6 cd is similar to what I was thinking of originally.

True, the 9. Nb5 line seems rather different than what I was thinking of.  Checking a couple of books, I see that they both think that 9. Nb5 is dubious and that Black should play 9...cd 10. Nc7 Nxe5 11. Nxa8 Nxf3+ followed by 12...Qb4+, though they differ on just how good it is (one gives it as leading to a decisive advantage for Black, the other just says that Black has compensation) ...



So, this is another line that Black will play in exchange down but with some compensation. Recently, i found out quite many of French line are being exchange down. For example: Black always play Rxf3.

Does it mean that i should pay more attention to Minor Piece Vs Rook ending more than others endings??

sorry, i made a mistake... what if white did not play f4 and play Nb5 on move 7, now it threat to take the pawn with check, a6 and Qb4+ won't work because white may play Nxc7 with check this time. So, i had to play 7. ...Na6 or 7. ...Nb6. Which move is better or is there any other better move/idea ??

ok, thanks dom. now i see why white can play Nb5 on move 8. how about  he play Nb5 on move 9? after black play c5, now white may play Nd6. In my opinion, that was a very nice outpost, it support by e5 pawn, and e5 pawn was support by f4,d4, and c3 indirectly...

Quete form kylemeister "  When I played the Classical French as Black long ago, I got the impression that Nb5 with the idea Nd6 was common among lower-rated players.  In general, White's centre will be collapsing (due to moves like ...cd and ...f6) while he undertakes this operation, so that he will end up having to play Nxc8 (in which case he has spent several tempi to trade off Black's bad bishop for him).  "

Kylemeister: if white play f4 and c3, then f6 and c5 can't destroy the pawn center. White will have two pawn on e5 and d4... for example: after 8. ...c5 9. Nb5 Nc6 10. Nd6 f6 11. c3 ...  (should black play 9. ... cxd4 to improve?? )

What if white play on move 10. Bd3 threat Bxh7, what should black play?? g6 or f5??





Against 7. Nb5, I recall 7...Nb6 being considered better than the main alternative 7...Qd8 (and it is surely more natural, no?).

True, the 9. Nb5 line seems rather different than what I was thinking of.  Checking a couple of books, I see that they both think that 9. Nb5 is dubious and that Black should play 9...cd 10. Nc7 Nxe5 11. Nxa8 Nxf3+ followed by 12...Qb4+, though they differ on just how good it is (one gives it as leading to a decisive advantage for Black, the other just says that Black has compensation) ...

If Black does play 9...Nc6, I presume that he should answer 10. Bd3 with ...f6.

8.Nb5 a6 9.Nxc7 Ra7 and the knight is trapped

or

10.Nb5 Nxc5

i have see many theory/books/video did not mention about the move Nb5...how should i face it?

1. e4 e6
2. d4 d5
3. Nc3 Nf6
4. Bg5 Be7
5. e5 Nfd7
6. Bxe7 Qxe7
7. f4 0-0
8. Nf3 c5
9. dxc5 Nc6
10. Qd2 f6
11. exf6 Qxf6
12. g3 Nxc5
....

why white never play Nb5 on 8-10?? Wasn't it difficult for black to protect d6 and c7??
