Your comparison to the Alekhine-Chatard Attack is BS too. In the Alekhine-Chatard, White sacks an h-pawn to open the h-file and gain a couple of important tempi for an attack in an openng where he is supposed to attack on the kingside. After 6. h4!? Bxg5 7. hxg5 Qxg5 8. Nh3 Qe7 9. Qg4, White has some dangerous attacking chances. He can play Bd3 with tempo right away, and moves like Ng5 and Qh5 will be annoying.
In the Advance Caro-Kann, White isn't supposed to attack like a madman. Black has done nothing wrong. He has created no weaknesses in his position.
Cheap tricks, I say.
Who says you can't be wild in the Caro-Kann? You can play move like g2-g4 and be as crazy as you want. I guess this cheap trick isn't so bad if GM's are losing against it.
When my ego was crushed as a kid the Caro-Kann was my back-up.
1. e4 c6 2. d4 d5 3. e5 Bf5 4. h4 h5 {( ... c5)}
5. Bg5 Qb6
6. Bd3 {( !? ?! )} Qxb2
What do you make of that, grab the pawn while leaving the bishop dangling?
