cxd4 9.cxd4 f6 10.exf6 Nxf6 11.O-O Bd6 {one of popular French tabiya's. 
White needs to keep control over dark squares, preventing e6-e5 
breakthrough and defending pd4. Black has a lot of room and open files for
attack.} 12.b3 $5

pd4. Ng5 was played to gain time and take control over b1-h7 diagonal. Now
it is essential to activate Bd7 for Black while White has to build up 
pressure and seek for tactical opportunities (remember that Black was 
Lothar Schmid, much better player than Paoli)} 16...Ne4 {taking up a 
challenge. Black heads for victory!}

much more space and pair of central pawns. White pieces and passive and 
cramped.} 20.g3 Rff8 {White cannot prevent e5-e4 so he tries to find 
escape for his Bishop} 21.Qd1 e4 22.Be2 Rf6 {Black is winning anyway but}
