Kibitzer's Corner
Apr-23-05  paladin at large: A very interesting game, full of intricacies. 31. Bh4 is quite a move by Portisch.
Oct-23-05  JohnBoy: Both 31.Bh4 and 32.Bg5 are beautiful moves. This game deserves wider recognition. When Hort played 15...Rd8 to protect his c pawn (after 16.d5 Qf5+ and ...Qe5 or ...Nb4 creates problems for white), Portisch just sort of shrugged it off and kept up the pressure. Very instructive.
Nov-06-05  JohnBoy: Let's keep this game on the discussion board - it deserves to be a GOTD...

  Mateo: As always with Portisch best games, his play was sound, solid and brilliant. This game shows how to create a mating net.

28.Rdh1! Rad8? <Of course, Black cannot take the pawn: 28...Bd4? 29.e5! mating. For instance, 29...Be3 30.Rh8 Kg7 31.R1h7 mate. 28...Qd4 29.Qd4 Bd4 30.e5!, the Black King cannot escape. 30...Kf8 31.Rh8 Ke7 32.Bh4. Or 30...g5 31.Rh8 Kg7 32.R1h7 Kg6 33.Bd3 f5 34.ef Kf6 35.Rd7! Nd7 36.Bd4 Ke7 37.Ra8 wins. But the move actually played allows White to create a mating net. Black should have played 28...c5! (29.dc Qd2), although White has the advantage.> 29.e5! <setting a mating net.> Qxd4 <Otherwise White mates quickly. 29...Qb4 (c6, e7, f8) 30.Qh3 (with the idea 31.Qh8) 30...Kf8 31.Qh8! Bh8 32.Rh8 Ke7 33.Bh4 f6 34.Bf6 Kf7 35.R1h7 mate. 29...> 30.Qxd4 Rxd4 31.Bh4! <Spurning the exchange in great fashion.> Kf8 <If the d8 Rook moves, then 32.Bf6 and the Black King is caught.> 32.Bg5! Nd5 <Now, if the d8 Rook moves, 33.Rh8! Bh8 34.Rh8 Kg7 35.Bf6 mate.> 33.Bxd8 Rd2 34.Bg5! Rxe2 35.Rxe2 Nc3+ 36.Kc2 Nxe2 <it seems that Black little combination was good, but...> 37.Kd3 <the Knight cannot escape.> 1-0

Apr-13-08  ToTheDeath: Beautiful combination in the style of Alekhine with the sting at the end of the tail- Black avoids immediate mate only to find his knight is trapped.
