Ottavio Vargiu (Italy) - Doug Hyatt (USA)









1. Nf3 ?!

A somewhat inflexible move which commits the g1 knight prematurely. This knight is a useful piece for delivering check on e5 OR g5 after the black king seeks safety on d7 or f7. The goal is to get the queen off, but a better way of doing this is 1. b4. I consider 1. e4 and 1. b4 to be the best moves.








2. e5 b5

Pawn moves are the least commital and should be preferred for 1- and 2-series. Here black opens lines for both his bishops. 2. e5 Nh6 prevents the removal of the queen, i.e. 3. Ne5 Ng6 Nh8 4. Bh4 Ng4 Nf2 Nd3++. But committing the knight to h6 is premature, and b5 is a better move.








3. Nxe5 Ng6 Nxh8 ?

White takes off the queen, but will lose a whole rook on the 4-series. This is most likely the losing series. White should play more slowly, i.e. 3. e4 b4 , but then his knight is clearly misplaced on f3.








4. Bxg2 Bxf1 Bg2 Bxh1

A much better series than 4. Bg2 Bh1 Bg2 Bf1. The bishop is harder to remove on h1 than on f1. Black is up an entire rook after his 4 series, and now has a won game. In general, if one side cannot equalize material at the end of his series (and cannot mate or force opponent to give check), then his position is lost.








5. d4 e3 Bf3 Kd2 Rxh1

At the end of this 5 series, white is still down an exchange. He has a slight lead in development. Perhaps slightly better chances would be granted by 5. e4 f4 Kf2 Bf3 Rh1, where white has moved his pawns two squares forward and has a more open field around his king. But the position is lost in any case.








6. d5 Kd7 Bf6 Nc6 Nxd4 Nxf3+

Black wants to play Nc6-d4-f3, so it is just a matter of finding the remaining three moves that are the best. 6. d5 c5 Kd7 Nc6-d4-f3+ allows 7. Ke2 Nd2 Nf3 Ng5 Nh7 Nf7 Nf8+, and I can find no win for black. I think the resulting position would be a draw. Bf6, however, develops the rooks and stops such a series by allowing Rxf8 in response to Nxf8+. It also blunts the a1-h8 diagonal, so white must spend 4 moves to take off the f8 rook with his a1 bishop.








7. Ke2 Nd2 Nxf3 b4 Bxf6 Bxg7 Ne5+

White finds a nice disruptive series, but he is simply down too much material to survive.








8. Ke6 f6 fxe5 e4 Rf7 Rxg7 Rg1 Rxh1

The two key moves in this series are Ke6 and e4. If black plays Ke7 instead, white can promote and win all of black's pieces. On e6, white ensures that the c8 rook and d5 pawn must be taken with check, and stops these series. e4! is a strong move which prevents mate (queen on f7, pawn on c5 mates if king doesn't have the e5 square).








9. Resigns

White can stop black from promoting with 9. Nf7 Nd6 Nc8 Nd6 Ne4 Ng3 Nh1 Kd3 Kc3, but black delivers mate with his pawns, king, and knight, i.e. 10. a5 a4 Nh6 Ng4 Nf2 Ke5 Ke4 Ke3 Nd1++ Instead, white can queen, but black will queen on his 10 and win all of white's pieces (or checkmate him with Qc1, d4-d3#).
