If you play 4...Bg4 pinning the knight, what does white do?
Annoying E4 to E5 by White in Sicilian

I like 2g6 and nh6....a g5 by white terminally weakensthe light squares. H4 is not dangerous. It is a very positional line. But, if you study it on your own you can learn something about positional chess
Go over some possible lines and what you think might give you difficulties. Maybe I can give some suggestions there

I agree with sko. for a little bit. I don't like his follow up though. However, I like the first 2 moves.
It is a French/Caro kann position on steriods. Its like a upgraded version of both lines which is better for black.

slightly better not to play Bf5 and hold back for White to play Nf3 and then pin the knight with Bg4.

I actually like the 2...Nc6 move order here because it makes White declare how he is going to defend the e5 pawn - with Nf3 blocking the f pawn or with the committal f2-f4. If 3.f4 then e5 is going to be well fortified and Black should play 3...d5! to go for the blockade on the light squares.
If 3.Nf3 on the other hand maybe Black wants to try to increase the pressure on e5 by playing 3...d6 instead of ...d5. It's not clear how White plays after 3...d6 actually. Black may already have an advantage.

the bishop might get useless/ get trapped on f5
I don't mind trading off the LSB. My idea is to have my pawns on light squares. I like the idea of provoking white to play moves like g4 etc. trying to trap my bishop.
I also do not mind playing 2...Nc6 before my bishop move. The only thing I didn't really like about your diagram was the d4 pawn push. I guess you was trying to gain space. However, does seem like a very over stretching move to me.

Easy refutation to this line I came up with. I'm about 1400 strength. My rating in blitz is low due to frequent encounters with engine users. However,I destroy people in this line with a pawn sac.here's the line : 1.e4 1. C5 2. E5? 2.nc6. If white plays f4, play g5. They play nf6 play bg7 then play f6, attacking the e5. Exf6 nxf6fxg6 nf8nc3qc7 then follow up with b6, bb7,o-o-o, challenge the g pawn with h6, put your knight back on f6 centralize your rooks and push the central pawns. I beat someone in 21 moves doing this

well this is the ideal setup for white, so getting white out of his comfort zone is what you want:
It is a French Advanced with no bad Light Square bishop.
I would take black.

after 1. e4 c5 2. e5?? White has given up his first move advantage and Black actually has some advantage.

No flame intended but it seems obvious you are playing against unskilled players using the e4-e5 move. Violating the opening rule of never moving the same piece or pawn more than once in the opening UNLESS you have a good reason.
Researched the e4-e5 in my Sicilian DB with no return. Researched in a 2 million game DB with less than 20 game return.
Anylized the e4-e5 with Database Software SCID (free off the internet) according to Toga engine ...Nc6 is your correct reply.
Do you have chess database software to anylize your games? If not SCID is fully functioning & free with a users group here at C.com. Of course there are many other Chess Databsase programs out there.
I suggest you consider geting DB software anylize all your games then review them especially the first 15 moves
What is a good way of being able to respond to this from WHITE? I generally try not to play f6, as that opens up a line to my King (and even if I do with hopes that WHITE takes and I take back with my f6 Knight to develop, WHITE is often smart enough to not take and just sit there with that pawn cramping my whole Kingside), but can't seem to find a smooth way of evicting/taking that pawn and developing my pieces.
