One of the game I played C6, then D5. I won the game but it seems that he is pretty good at Caro-Kann too.
Should I replied it with Nf6? since I like to play KID against D4, is there any risk if I play Nf6?
When deciding what to play against 1.c4 or 1.Nf3, you must account for what you play against 1.d4 or 1.e4 as it can transpose. For example, if you do not play the Sicilian, then 1.Nf3 c5 is a mistake because White can play 2.e4 and you are stuck in a Sicilian. If you are a Sicilian player, then 1...c5 is fine.
If you hate double queen pawn openings (d4 d5), then 1...d5 is a mistake against 1.Nf3, but if you like 1.d4 d5, then 1.Nf3 d5 is strong.
1.Nf3 is very transpositional, and this must be accounted for.
I use to play Sicilian, but I rarely play it anymore since I learned Caro-Kann, recently I tried the Grunfeld and have a successful score with it, I think I would start to play with it now.
Just Play The Dutch
Kingside or Queenside Castle, I usually Queenside in this imbalanced positions.
I never saw a queenside castle the dutch in a high-level game, but it is a very interesting opening to learn and play at club level. I think I will try to use it more.
So, if white plays Nf3, what should I reply to bait white to play D4? since NF6 is not an option because of black blocks the F pawn
Indeed. I particularly find it offensive (personally) whenever someone doesn't like DQP openings. I'm not going to be passive-aggressive here, rather be totally upfront with you young pups...it's an absolute must to ingrain Queen's Gambit theory, either with white or black into your overall opening repertoire. And it's not only COOL to answer 1. Nf3 with 1. ... Nf6, it's OP man. Central control much? Every basic opening principle in elementary text expounds on this even if you don't know much theory. Please. Dont get me started on why I think the Slav is not analogous to the the CK. Please. I'm an Caro Kann player myself, and I would never ever advocate someone else to play the Slav or Semi-Slav just because. If it works for other players, cool. But essentially in this context, you and your opponent (who plays the CK & Slav) imho are not that. Fault me for my sanctimonious attitude, but I dont care because I'm not the one asking for advice. If spongey's or Thriller's replies dont resonate with you, nothing will but just experience. Just play. Because playin's always the thing with me. Dropping dimes of knowledge is useless if you're just a nitpicky. I advocate for opening study first n foremost, but not outright ignorance of basic fundamentals of opening play in lieu and reluctance to expanding one's knowledge. Please. Peace.
You talk a lot, and I don't even understand with what you are even talking about
