Not true. Jrobi is simply informing us about book moves (‘common reactions to said variations’). While you are right in saying your opponent is not going to go 100% by the book, it helps to learn main lines and variations.

For example in the Sicilian Najdorf line, Black goes 4… Nf6, attacking the e4 pawn. From here, Black can do numerious things to protect it, but the most common (and the most EFFICIENT) reply is 5 Nc3. It helps to know common reactions and replies in the long run.

Totally agree lpjuunin – it’s very helpful to understand common replies in opening lines, along with other forms of chess study. Thanks for checking out the vid and commenting!

“Queen d8xe2″ is the funniest thing I heard today.
well if after h3 the black Bishop takes on e2 white can simply recapture with the bishop on d3 opening the line for the queen to protect the d pawn.
I dont see much advantage for both sides.. maybe black causing a backward pawn at e3 playing knight to f5 and trading it with the protecting bishop on e3 which looks weaker though… its pretty tough to play against booklines. I dont suggest it to anybody ;/

I responded to Adam177man :p
I would expect more “action” after blacks first knight moves. it has not much difference to many Indian defences messed up by black.. but its nice to see how to get a decent activity though the position looks cramped. but if someone really has “learned” how to handle this difficult situation, hat off. its quite impressive.

if we simulate a game we have to ASSUME moves, thats basic stuff
everyone knows the real deal is always unpredictable

Blk rook could have moved to b8 with protection of the knight on c6 to make the queen retreat. Nobody plays these book lines to the depth shown here. Fischer played it differently and most likely better than book!

Good

couldnt white just avoid the extension of his/her pawns by using the knight on b to protect the pawn?

what is move 13 for white. You jumped from the black bishop moving to (bg6) on move 12 to black’s move on 13; bxd3. What if white decides to take the bishop on g6 and exchange. Wouldn’t that weaken the Alekhine?

i was wondering what you guys think about this variation of the sicilian

e4 c5
nf3 d6
d4 cxd4
nxd4 nf6
nc3 nc6
bc4 g6
be3 e5
ne2 be6

its a mix of the dragon and the opocensky the idea is to liberate the f file by exchanging bishops and allowing a better defense against the yugoslav attack, black can also castle queen side and has a much more flexible position.
