The Vote Tally -------------- The winner is: 14 ... Ne8 There were 16 votes. We had a wide mixture. The group seemed to have difficulty forming a plan. Many different plans were suggested.

N:e5 and white wins a pawn) 16. Q:f3 Nf6 (now we've lost the bishop pair, a tempo and the knight still blockades the f pawn and the white queen is active...) (if 16 ... g6?; 16. Bh6 Ng7; 17. g4 and black can't support f5 because the light square bishop is gone) while 14 ... Nd7?; 15. h3 Bh5; 16. g4 Bg6; and black has trouble supporting f5. I expect play to proceed: 15. h3 Bd7 16. g4 g6 17. Bh6 Ng7 18. Qd3 f5 (at last!) 19. g:f5 g:f5 JPERRY@SRI-KL In keeping with the obvious strategic plan of f5, I vote for 14...N-K1. N-Q2 looks plausible but I would rather reserve that square for another piece. SMILE@UT-SALLY 14 ... Nh5. Paves the way for f5. Other possibility is Qd7 first. Either way I believe f5 is the key (as it often is!). REM@MIT-MC I'm not much for attacking correctly, so let's prepare to double rooks: 14. ... Q-Q2 (Qd7) (It also helps a K-side attack if somebody else can work out the details.) VANGELDER@SU-SCORE 14. ... Nxe4 (vote) In spite of what the master says, White can indefinitely prevent f5 by h3, Bd7, g4. Will the computer find this after Ne8 by Black? Stronger over the board is 14 ... Nxe4. If 15. Nxe4 f5 16. N/4g5 f4 and Black regains the piece with advantage. The majority will probably not select this move, which may be just as well, as attack-by-committee could present some real problems. Nevertheless, the computer presumably saw and examined several ply on this line and it would be interesting to see what it thinks White's best defense is. An alternate line for White is 15. Nxe4 f5 16. N/4d2 e4 17. h3 Bh5 18. Bd4 Bg4!? 19. Nxe4 fxe4 20. Qxe4 Bxf3 21. gxf3 Rf4. There are many variations, but most are not decisive in 8 ply, so the computer's evaluation function would be put to the acid test. ACHEN.PA@XEROX 13 ... Nh5 (keep up the pressure) this might provoke 14 g3 Bd7, either 15 Nd2 or h4 to start a counter attack. the black is hoping to exchange the remaining knight with queen's bishop 16 ... Nf4 then maybe attempt to encircle the white with Qb6 attacking the weakside behind the pawns. (note: if 13 ... Nh5 can't 14 ... f5 for the obvious reason) Solicitation ------------ Your move, please? Replies to Arpanet: mclure@sri-prism, mclure@sri-unix or Usenet: ucbvax!menlo70!sri-unix!sri-prism!mclure
