25. f5 {[#]} g5 $1 {Another move that surprised the commentators! So what was
my thinking process during the game? This looks positionally suspect as I'm
willingly weakening my kingside.   The key to the position is that Sophie has
a simple idea of gaining space on the kingside with g3-g4-g5, exploiting my
lack of kingside pieces and making use of her space advantage enforced by the
f5-pawn. As we were both getting low on time, I didn't want to have to defend
against an attack on my king, especially as time pressure favors the attacker.
So by playing ...g7-g5, I prevent the kingside advance, and I can even start
my own attack by pushing my pawns and limiting her light-squared bishop.   I
give this move an exclam because the engine evaluation might be equal, but my
initative (and the psychology of forcing Sophie from attack to defense) gives
me a practical advantage.} ({Another idea is} 25... Bd4 $5 {opening the
c5-square for the knight because the bishop is untouchable for tactical

come under attack and, if I quickly mobilize my pieces, I can pick up one of
the weak c3- or f5-pawns.} Re8 37. Qd2 Be3 38. Qd3 Qd8 39. Qb5 ({Black has a

Mateo, California September 22, 1989 My final tournament in the Santa Cruz
area was the World Action Championship. I faced 13 masters and senior masters
in this event and more than held my own, playing several great games, which
included wins over two grandmasters The highlight of any player’s career
must be a win against the strongest player in his country. This game was
played in the first round, on board two. In mutual time pressure Walter did a
bit of his famed nervous fidgeting. The game was of intense interest to
spectators; I could not see the walls of the room; our table was completely
surrounded. The game was published in Chess Life, the San Francisco Chronicle,
and the San Jose Mercury News, all showing the correct result. In their story
Chess Life implied that Walter deliberately lost this game. What do you think?
It has been a major disappointment that the online chess databases all have
the result reversed, showing the game as a loss for me. I do not know how to
get that fixed.} 1. e4 c5 2. c3 Nf6 3. e5 Nd5 4. d4 cxd4 5. Nf3 Nc6 6. cxd4 d6
