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!? 4. Nc3 d6 5. e4 g6 6. Bd3 Nbd7 7. g4!?

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. 8. g5 Nh5 9. h4 h6 8... a6 9. h3 Bf8 10. Be3 h5 11. g5 Nh7 12. h4 Bg7 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!!

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 exf4 21. Nge2 Ne5 threatening Nf3+ 22. Kd1 Qxg5 23. Kc2 Protecting the bishop, but 23. Na4 b5 24.
