What are White sharpest lines against various black defences?

I know I've already asked this question for the Sicilian defence and I apologize

the reason I'm asking is because I've figured out that if you're playing against someone who's <100 rating points than you  and you're risking to lose the triple of the points you would earn, maybe I'm mistaken, but it's better to go for a quick kill, because the longer the game last the higher is the probability to blunder

vs e5 it's not a problem there's ample choice between KG, Max Lange attacks, Fried Livers, Urusov gambits etc...

vs c5 they told me the best choice is just to play the open mainline Sicilian

but what about the other defences? e6 and c6 seem to be almost designed to blunt a sharp attack from White

vs d6 I've heard about the Austrian attack but what about Nf6,  d5 and other minor defences against e4?

Thanks for your advices and I hope this thread to be useful to other readers too

Personally I feel that the sharper the game is, the higher the chance that an upset happens. I try to keep it simple against lower rated opponents, since they'll probably make a mistake somewhere, and make the game as messy as possible against better players.

Against 1.e4 e6, I think you need 2.d4 d5 3.Nc3, and if Black goes for 3...Bb4 then there are plenty of attacking lines. Against 3...Nf6 it's harder (I don't really know) and against 3...dxe4 you're out of luck, it's rather passive but very solid.

Against 1.e4 c6, there are many sharp lines within the Advance (1.e4 c6 2.d4 d5 3.e5), e.g. after 3...Bf5 4.h4 (or 3...c5 4.c4!)

 Thanks in my case I played Stonewalls (both colors) for months and I got nowhere . I suppose that vs the Alekhine you have to play the 4 pawns variant and vs the Scandinavian there's the Mieses b4 gambit but I'm not sure ...

I also recommend to keep it simple against lower opposition and to complicate against stronger players. I know that is more common to to the opposite, but this is really the best strategy. A stronger opponent will flawlessly outplay you in a tacticallt simple position, and a weaker one is more likely to swindle you because of a single mistake is a sharp position.

I played the Alekhine for a long time and i discourage you from taking up the four pawns attack without studying very hard and being a very strong player. My score against equal opposition with the 4PA used to be around 90% for B.  And not because the 4PA is weak; in fact it's a strong weapon when handled by a GM. BUT B can trow at you a dozen of semi-sound ultrasharp replies. Without a great preparation you have strong chances of being really lost out of the opening. W tactical chances tend to appear later than B ones, this is the practical problem. In fact i used to be very happt to see 5.f4 on the board.  What do you play against 1...e5? I can suggest you a practical anti-alekhine line depending on the response.

 I play this:

In was almost thinking to play this vs the Alekhine so if black is merciful I can transpose to the previous diagram

What's your saying regarding the Caro and the French?

Oh right, you said that you play the urusov on the smith-morra thread, sorry.

2.Bc4 against 1...Nf6 is not a great move in my view, but might work as a shock weapon. The final position in your line is not unpleasant at all for black, the bishop pair+central majority more than compensating for the misplaced king. I would call the position slightly better for black but easier to play for W, possibly a good weapon for a quick time limit. Another problem is that B has quite a lot of alternatives to 2...Nxe4, including 2...e6 and the bizarre but strong 2...b5!?

A quick anti-alekhine if you like open games is 2.Nc3, when 2...d5 is a bit under a cloud according to john Cox in his alekhine book and 2...e5! trasposes to a vienna, which is quite a close relative of the bishop opening. Then you might try 3.f4 where B obtains a pleasant game with 3...d5(3...exf4? leads to a huge white advantage), but the resulting positions are quite open and sharp. You might like it (and an average alekhine played might not, even if i personally do) .

i'm not really an expert on the french and caro, i would like to hear other people suggesting something. Against the Caro i have recently decided to take up the Panov, but have not played any game yet.

It seems a line fun to be played although I think the common response will be d6 instead of d5

If you mean 2...d6, i have two remarks:

1- i don't think 2...d6 will be common at all since it leads to completely different defenses (either pirc or philidor) and a player who starts with 1...Nf6 is unlikely to be willing to play these lines. True,2...e5 also leads to another opening but at least it's a standard open game in which everyone should have a bit of experience. 

2.Even if they do, where's the problem? you already need something against 1...d6 2...Nf6 which is more common than the alekhine. So after 2...d6 you just traspose to your favourite anti-pirc and anti-philidor line. Since you are interested in a "bloody" repertoire you will probably play the austrian attack(EDIT:very good, you already play it :)) against the pirc and maybe shirov's gambit against the philidor. Both are truly dangerous and aggressive. So with 2...d6 black is just inviting you to play a different but even more dangerous line of your repertoire, in an opening for which he is probably not very well prepared.

No  I meant d6 later like this  ....

I have just 1 question for you Mr Bresando . I'd like to switch from the French Defence to the Sicilian as Black. What (sound) setups should I learn IYO to cover  all White can trhow at me? Closed - Open Sicilian and Sidelines included. The more simple and compact the setups are the better . Thanks anyway

I am really not an expert on the sicilian and i have never played it as black,sorry.

4...d6?! doesn't really deserve consideration, maybe 5.Ng5!? is an even harsher punishment since i can't see anything better than 5...d5 with a tempo-down version of the otherwise strong two knights defense. B must be close to lost here.

Against the french I would reccomend 2c4.
