London System Classical 5...c4

The London System is a reliable opening that counts on basic safe development. White has solid control of d4 and looks for opportunities to play for c4 or e4 after all his pieces are out. In an APCT game, Bernie Burke chose a classical set-up with the moves 1...d5, 2...Nf6, 3...c5 and 4...e6 in much the same way Black would handle a French Defence.

Burke pushed his c-pawn on to c4. The point of this move is to prevent White from playing 6.Bd3. This logical strategy has some flaws.
1. White's d4 is no longer under threat of pawn capture.
2. White can attack the pawn chain with e3-e4 or b2-b3.
3. White's light squared bishop is more active than Black's.

As the game unfolded White had a slightly better position. Black was forced to defend his lone a-pawn. Then as often happens, a tactical oversight leads to a quick finish.
