1. d4 Nf6 2. c4 c5 3. d5 e5 {Tate also plays the Benko Gambit. Sipke has also
played this line, so he would have been prepared for} (3... b5 $5) 4. Nc3 d6 5.
e4 g6 6. Bd3 Nbd7 7. g4 $5 {Diagram # This is characteristic of the young
Dutch player who adopts an aggressive style. While not immediately dangerous,
it threatens to gain space on the kingside and restricts the mobility of
black's pieces. If white's king bishop were on e2 instead of d3, then the
position would be more critical since black wouldn't be able to play ...Nh5.
This game turned out to be remarkably similar to game #9 of the
Spassky-Petrosian 1969 match. That game was drawn after 65 moves.} 7... Be7 (
7... Bg7 {is also fine, but black has a change of plan after white's
provocative move. If white ever plays g5, the bishop on e7 will work on an
assaulting the pawn advance with a move like f6 or h6.}) 8. Bh6 {
Trying to confine the king to the center while preparing to pry the flank open.

Now the game settles down and Tate strategically outplays his opponent.} 13. a3
O-O 14. Nge2 f6 {Natural break which exposes white's fixed structure.} 15. Qd2
fxg5 16. hxg5 {Black's position is fairly solid and the passed h-pawn demands
attention, but Tate has a deep idea in mind.} 16... Rb8 17. b4 b6 18. Rb1 Ra8
19. Ng3 Rf4 $3 {Diagram # In this type of structure, black usually tries to
put a knight on this square, but this exchange sacrifice is also very powerful.
Petrosian used a similar idea in the aforementioned game against Spassky. For
the exchange, black gets the dark squares and a nice square for the knight.
Once the knight lands on e5, black will have a strong compensation.} 20. Bxf4

but black still has good play.}) (23. Nxf4 $4 Nf3 $19) 23... b5 $1 {
This break opens up more fronts to the exposed king.} 24. Kb3 $4 {
Feeling immense pressure, white blunders.} 24... f3 $19 25. Qxg5 Nxg5 {
Black will now gain a material advantage.} 26. Nf4 Nxd3 27. Nxd3 Bxc3 28. bxc5
