Robert signalled that it is time to talk about the sniper. What's the idea behind the opening?
The sniper in the move order as I want to play it, starts with the moves 1. ... c5 2. ... g6 3. ... Bg7. It's a hyper modern opening, and the idea behind that type of opening is commonly known as "give white the pawn center and invite him to overextend, then attack the center from the flanks".
The sniper is coined and elaborated by FM Charlie Storey. He made a DVD about it. It was picked up by GM Ron Henley too, who made a series of videos about it.
Storey noticed that if you have the mentality to play for a win with white and for a draw with black, you always end up as second or third in a tournament, at best. If you want to win a tournament, you must play for a win with black too.
So he "invented" the Sniper. General ideas:
- play for a win with black
- play for an unbalanced position
- minimize risk
- try to get the pawn majority in the center
- work towards an endgame once you get the majority in the center
- use 1. ... c5 2. ... g6 3. ... Bg7 against anything except 1.b3 and 1.b4
- search for messy positions without theory
- since black has less space, to trade a piece is a good idea
- in certain cases you go for the Hyper Accelerated Dragon
- there's little chance to get checkmated before move 25
Sorry, typical "senior moment": I went backward through your posts and found where you discussed trying a new opening (HAD - HyperAccelerated Dragon) against 1. e4, with (possibly) a different opening (the Sniper) against other preliminary moves. That would remove from consideration several of the variations I gave.
ReplyDeleteCan I assume that 1. e4 c5 2. Nf3 g6 3. d4 Bg7 is your chosen opening sequence under consideration as the Sniper against the typical Open Sicilian move sequence?
Your assumption is correct.
Deletee4 and d4 is referred to as the dynamic duo. Or Batman and Robin. The third move being:
Nc3 - Manchester United variation
Nf3 - Arsenal variation
c4 - Chelsea variation
f4 - Manchester City variation
h4 - Leicester variation
Further you have the Pterodactyl attack, the Diplodocus, the Bermuda Triangle (where pieces tend to disappear in an inexplicable way) and the Botvinnik setup.
My stockfish tells me that
ReplyDelete1.e4 c5
2.Nf3 g6
3.d4 Bg7
is very bad because of
4.dxc5
If you like lets make some computer moves?
Then I play the HAD
Delete1.e4 c5
2.Nf3 g6
3.d4 cxd4
Storey goes to great lengths to computer check all the variations he advices.
ReplyDeleteHe couldn't get
1.e4 g6
2.Nf3 Bg7
3.d4 c5
to work. Since black simply loses a pawn with little or no compensation. Notice how he uses a different move order. He advices to transpose to a Pirc by 3. ... d6. It is a harmless Pirc, since white has already played 2.Nf3, so the dangerous f4 is avoided.
I played the Pirc in the past with (too) little success. So I decided to change the initial move order and transpose to a HAD. Which requires the same state of mind as the Sniper, to my belief. At least for how I intend to play the HAD.
Given your decision to change variations to HAD [1. e4 c5 2. Nf3 g6 3. d4 cxd4], the following information may be moot. It is interesting that several Black players decided to risk this variation. With this approach to the opening, transpositions RULE!

I made an attempt (laughable, at best) to play the Black side of a Modern Defense. Obviously, this is NOT my usual response to 1. d4; I prefer 1. … Nf6 with a “wait and see” attitude toward whatever structure White has planned. For “comic relief”, here’s the BIZARRE game I played against Stockfish at level 4 (5 min + 3 sec) on lichess.com. NOT the “recommended” way to play the Modern Defense! (And, NO, “All's Well That Ends Well” does NOT apply.

You found the two core ideas of the opening: with a majority in the center, a flank attack from the opponent can never succeed, and mate ends the game.
