Adams found <17.e5!>, which breaks things open for his rooks and vacates e4 for his Nc3. The immediate threat is exd6, attacking both the N (with the pawn) and the bishop (with the rook). Moving the bishop to safety (e.g. 17...Bc8) still loses since 18.exd6 exd6 19.Ne4! and now either Pd6 or Pc5 must fall. Capturing with 17...dxe5 leaves black's pawns in shambles, and is quickly exploited with the discovered attack 18.Qe3! After black moves his Q, say 18...Qc8, white recovers his pawn plus attack with 19.Nxe5!

The knight is immune: if 19...fxe5? 20.Qxe5+ Kf7 21.Ne4! (threat: Ng5+ & Nxe6) Capturing with <17...fxe5> (as in the game) still leads to <18.Nxe5!> because if 18...dxe5, then comes the discovered attack on the queen 19.Qg5 Nd5 20.Qxe6+ Qf6 21.Qxf6 Rxf6 22.Nxd5 Bxd5 23.Rxd5 -- and black faces and endgame down a pawn and 3 isolated pawns for the rooks to attack. Black continued with <18...Qc8> (unpinning his Q to threaten ...dxe5), but from this point on, white controls the board with the strong central rooks. After <19.Ng4> (moving the N out of take), black played <19...Ng8?> (to unpin his LSB, although at g8 it cramps his king's mobility -- 19...Nc6 was better). White punished this with <20.Ne4!> to end the game.

The threat is Qc3+ leading to an all-out assault. The best black can do would be 20...Bxg4 21.Qc3+ Kh6 (note 21...Kf7? 22.Ng5#) 22.hxg4 Qxg4 23.Rd3! (threat Rh3+) Rf5 (to defend via Rh5) 24.Rg3 Qf4 25.Rh3 Rh5 26.Rxh5 gxh5 (not 26...Kxh5? 27.Qh3+ Qh4 28.g4+!)

27.Nxc5! (opening the e-file and threatening Ne6) Rf8 (not 27...dxc5? 28.Re6+! Kf5 29.Qxc5+ Kg4 30.f3+ Re4 pins Q ) 28.Re6+ Rf6 29.Rxf6 Nxf6 30.Nd3 Qf5 31.Qxc7 and again, black faces a pawn-down endgame where his remaing disconnected pawns are hopeless. |
