I fail to see what's so strong about b4 for Black. On the other hand, 1. Rd2 Qc7 2. Be2 looks good for White because of that tasty square c4 indeed. I might be completely off here, though, this may be quite a bad plan and White may have played something completely different instead 😛 Merry Christmas!!!~~~~!!

b4 isn't terribly impressive. The Pawn on the c file is blocked by his own Knight and the a Pawn is advanced to the 4th Rank so again, tough to dislodge the N.
The c3 N can't move forward because of the Black P on c6 which the b4 N is guarding.

Speaking of strong/weak squares.
One of the stongest squares, the most proctected at the start of the game
is e2 (the other being d2).

The e2 pawn is protectd by 4 pieces.
We play 1.e4 and...

...it's on it's own. (just a thought).

Originally posted by Ice Coldthanks Ice man, irontigran, heinzkat, AudreyxSophie, Marsan, AThousandYoung, greenpawn for the insight. This is truly a wonderfully instructive game, Karpov gets his queen to that c4 square, after exchanging his white squared bishop for a knight that was coming to cover the c4 square, he uses the half open f file for his rooks after manoeuvring his other knight over to the king-side, kicking the dark squared bishop away which was preventing his rooks coming to the f file, and the culmination of the pressure from the rooks down the f file and the queen on c4, blacks game cracks!
