Here I went with b5 planning to weaken his queenside a bit, I didnt have anything concrete but eventually I thought I could do b5 then Qc7 and put some pressure.

I want to see how you guys evaluate this position and what plans you have in mind.

This position looks pretty bad for Black. Black is several tempos behind with his counterplay and White's attack with g4 is coming fast.

There's nothing much else other than b5, hoping for White to misplay the attack.

This is obviously coming out of a Sicilian Dragon. Though, it's strange to see White without his light-squared bishop. I assume a 1...Nc6-a5 2. Bc4-b3 Na5xb3 3. Nd4xb3 exchange happened.

White's g4 threat has a known defense. Black basically ignores it and attacks with pieces on the Queenside. If White plays gxh5, then Black recaptures with the knight and blockades the h-file. White's pawn storm and attack on the kingside isn't getting there without the light-squared bishop participating in the attack. In addition, the dark-squared bishop is oddly placed on d4.

An experienced Dragon player knows he wants a rook occupying c4. With the light-squared bishop gone, Black should be able to immediatley play it, and then double the rooks on the c-file.

The move ...Rc4

Black has gotten an advantage out of this opening.

Sorry this is completely wrong. Rc4 is a decent move, but White still has many ways to get an advantage for example e5, Rhg1, or Qe2, Nd5, even Bxf6.

Your plan of defense against White's g4 does not work. Just a sample line 1...Rc4 2.Rhg1 Be6 (it's necessary to cover d5 before moving the Queen or Bxf6 Bxf6 Nd5 will be crushing) 3.g4 Qc7 (not the best move) 4.gxh5 (or Bxf6) Nxh5 5.Bxg7 Kxg7 6.f4 and White wins.

what lines do you know where white usually keeps his light squared bishop in a Bc4 yugoslav?

I don't frickin now what to play anymore

Is the point of Be6 to protect the d5 square?

Yeah, mainly it's that. My first thought was to play a5 right away, because it forces white to make some decisions. However, white can proly just take on f6, play Nd5, and attack f6 and a5. But if we play Be6 first, then a5-a4 doesn't go anymore. So tbh I am kinda lost. I would probably end up playing Be6 though, covering d5 seems paramount to whatever black wants to do later on.

Maybe I was too excited about ...Rc4 immediately.

Black erred in playing ...Bd7. It belongs on e6.

He also wasted a move with ...a6.

Black really needs to learn how to play the dragon to avoid such positions in the first place.

One of the main lines of this opening goes:

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. O-O-O Rc8 11. Bb3 Ne5 12. h4 h5 13.Kb1 Nc4 14.Bxc4 Rxc4

and here one of White's options is 15.Nb3, which scores quite well for White.

In the position in the thread, Black is just two tempos down compared to this position (the move a6 doesn't really change anything).

Agree with pretty much everything John_Douglas is saying. This looks like a dragon minus two or three tempi for black. No bueno.

Bearing in mind my patzer status.

From memory - many defences for black here revolve around playing with an exchange down and counter attacking chances on the queen side.

Yes we are going to have the pawn storm down the kingside - but we cannot really accept just defending.

My view is for a pawn storm - is that without the c3 Knight and its e4 /d5 pressure white with a poorly placed knight a long way from the attack - that he might consider Rxc3
This might give us a chance to activate our other rook (through either an exchange of queens and/or enabling our queen to reroute to enable to activate) + a chance to improve our white squared bishop without closing the c-file.

Anyway - I suggest Rxc4 or a plan to do it at some point soon.
Everything I have been taught about the sicilian is whoever controls d5 wins. - mostly

Slight derail: thinking like this during a game is, at least for me, a guaranteed source of blunders and missing really obvious replies. I've fallen guilty of it a few times and try my best to avoid it. Ignore concrete variations at your peril
