Is Albin Countergambit is good opening against the Queen's Gambit


that's with every opening; + black should be happy with a draw
Nah, White can try to "bowdlerize" the Sicilian for example, but there's still going to be some kind of imbalance just because the pawn structures are asymmetrical (and flexible for both sides). But in the Exchange French/Slav White is literally just one tempo up in an inflexible structure. Black can play for ...c5 or ...e5, respectively, but of course that's taking on some risk. And I don't think Black should necessarily be happy with a draw, not in casual chess or against a lower-rated player. If we were arguing about theory and not playing chess, then maybe that would be the case, but I don't see why you shouldn't play for a win with black (as long as you're making sound moves).

nope he said it its the top sharp openings and he never said that slav is sharp. He said the slav is a solid opening that i should not bother with because its clearly not compatible with my playstyle its sad that you tjink the the borinf slav is sharper than the botvinnik.
And i watch the you tuber you name he never said the slav is the sharpest and he said things about the opening i name so
Then your coach is trash or he doesn't know about the Anti-Moscow or Botvinnik existence. The Youtuber I mentioned I just copied and pasted the description. Can you even tell me the line of both of the Botvinnik and the Anti-Moscow? Also this entire time I've been talking about the SEMI-Slav, which might be why your coach didn't mention these variations, because despite the similarity in name they are completely different in playstyle and sharpness.
I'm moving this discussion to another thread. Clearly it's sad news for chess if a 1700 tries to coach us on which openings are sharp and not.
ouch, straight to the rating move

The Benoni and KID are definitely sharp (I don't know how you can deny that the Mar del Plata is sharp, at least; one move can be the difference between White surviving on the kingside and getting mated), but not Botvinnik-level sharp. Of course White can take any of those openings and steer the game towards equal, but peaceful waters, and if they know that you're a booked-up and aggressive player (not really possible online of course, but OTB), that might be the smartest thing to do.

its playable in blitz/faster games
but in classical times, its unplayable
Nope until master its a fine wepeon for i win
defintiv better than slav
Yes let the 1600 coach us on how the Albin CG is better than the Slav. Buddy just play properly in the Slav and it's exciting. Both Anti-Meran with h6 Bh6 and the Botinnivik Slav is top 10 sharp material
Two knights defence, traxler counter gambit, Max Lange attack, Blackmar diemar, KID, Benoni, Tarasch Defense, Millner Bary, Sicilian Wing gambit, Falkbeer counter gambit, Benko gambit, Jaenisch Gambit ....
All more sharp and i could go on
The Bg5 Semi-Slav is much, much, MUCH sharper than everything you listed with the sole exception of possibly the sharpest of KID variations (in which it is only much sharper). I noticed that you listed mostly gambits, but… Gambit = dubious. Dubious /= sharp. The reason you think that gambits are sharp is because you know the theory of the refutation line, and forcing theory is what makes something sharp, but as gambits can be refuted very easily by and large (especially most of the ones listed) they will never be as sharp at top level. Meanwhile, the first sideline in the Botvinnik literally STARTS on move 13 at the earliest, and the mainline starts on about move 18. Your Benoni and Benko have NOTHING on the Bg5 Semi-Slav.

A lot of those gambits *are* positionally sharp, because there are a lot of imbalances and decisions to be made. Yes, you can refute (most of) them and get a good position, but the game will still be imbalanced, unless you follow the theoretical lines all the way to the end. Nothing compared to the total mess of the Botvinnik (although even at the end of those theoretical lines, you often find yourself in a fairly ordinary, if imbalanced ending), but if you're not at the top level (and are any of us?), then you're still not going to get an easy game, unless it's something really atrocious like the 3...Qe7 Englund.
The albin is damn OP in my level (talking about blitz and rapid surely), because there's still so many people that don't play the critical line and get caught up in the trap. Even if they prepared the main line, you stilll have a playable position. I absolutely love it, but higher rated folks will probably disagree
