For my sparring session on the Chapter on "passsed pawns" I chose the following game:

Reshevsky - Seidman [D92] New York, 1968

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Bf4 0-0 6.Rc1 c5 7.dxc5 Be6 8.e3 Qa5 9.Nd4 Nc6 10.Nxe6 fxe6 11.Qa4 Qxc5 12.Qb5 Qxb5 13.cxb5 Nb8 14.Bd3 Nbd7 15.Ke2 e5 16.Bg3 e4 17.Bb1 Rac8 18.Na4 Ng4 19.Rhd1 e6 20.Rxc8 Rxc8 21.f3 exf3+ 22.gxf3 Nge5 23.e4 dxe4 24.Bxe4 b6 25.Rd6 Nf8 26.b3 g5

Here Reshevsky notes the following: "At first glance it appears that black has nothing to be seriously concerned about; but white does have the advantage of the two bishops, and black is saddled with an isolated e-pawn."

27. Nxb6!

"A bolt out of the blue...blacks position becomes untenable. I get only 2 pawns for the piece but the passed pawns with the aid of the rook and bishops are not to be stopped by blacks forces."

27...axb6

28. Rxb6

Here is where I set up my sparring session with Fritz. I sometimes have trouble with the technical phase of games such as these and thought a position where I have only a piece for some passed pawns would be good practice.

Now Fritz continued 28...h5 (the same move that Seidman played)

29. a4

I deviated from Reshevsky's 29. Ra6 in the book he gives "29. a4 is stronger" but elaborates no further.

29...h4

30. Bf2, Ngf6

Through whites 30th move play has been very similar to the Reshevsky-Seidman game. In that game black played 30...Neg6. Fritz sparring session move undefends his weak e-pawn, but it cannot be taken as its an obvious trap due to the fork at f4 with check. The position has completely changed now from the actual game. Reshevsky used his bishops and rook to support his pawns, now I take a different course based on blacks variance.

31. Be3

Simple I want to exchange the knight if it lands on f4 and his pawn on e6 is hanging since it is no longer defended.

31...Nf4+ 32. 32.Bxf4 gxf4 33. a5!

Stronger than taking the e-pawn the passed pawns scream to be shoved down my opponents throat.

33...Kf7 34.Rb7+ Kf6 35.a6 Rc3??

The sparring Fritz blunders. IMO more logical was 35...Bf8 but after 36. a7! Bd6 37. Rh7! white wins.

36. a7! Rc8

37.b6 (diagram)

Black is crushed 37...Nc6 38.Bxc6 with a slaughter.
