Qe3 Nxe4 24. Nxe4 Rf4 {This looks like a logical move, but the vulnerability of the Black king is now exposed by a brilliant combination which also exploits the weakness of the seventh rank. First Lasker puts more pressure at d6.} 25. c5 Bf5 {Black has a simple threat, to capture at e4, and an indirect threat at c5, because if the knight moves away, then the pawn at c5 can be captured. So White defends one knight with the other.} 26. Nfg5 Qd7 { This answers the threatened fork at f7. But now White clears the path for his pieces with a queen sacrifice.} 27. Qxf4 exf4 28. Nf6 {Notice that the Black queen must guard the f7-square, otherwise 29.Nf7 will be checkmate!} 28... Ne6 29. Nxd7 Nxg5 {White is now ahead in material, with an extra exchange. But even more importantly, he can invade the seventh rank.} 30. Re7 Kg8 31. Nf6+ Kf8 32. Rxc7 {Here Black resigned, because the rook will continue his pillage of the seventh rank, and there isn't anything Black can do about it.} 1-0
