|KEG: Fine tactics by Pillsbury in a game with just heavy pieces (Queens and Rooks) and pawns.|
Tchigorin's play against Pillsbury's Petroff Defense was not always the best (his 7. c4 was inferior to Tahl's 7. Nc3), but after Pillsbury's 7...c6 (7...BxN would have been much better) and 12. Be6 (12...b6 was best), Tchigorin emerged with much the better position.
Tchigorin lost most of his edge with 16. c4 (16. Be5 or 16. Rae1 were both much better).
Pillsbury's 16...Be5 involved a clever tactical trick (17. BxB would have lost a pawn to 17...Qxd4+). Needless to say, Tchigorin didn't fall for this.
I agree with Sergeant and Watts that Tchigorin should probably have kept his Bishop on the board (given his more broken pawn structure) with 19. Bf4, but Tchigorin had King's side threats after his 19. Qg3 and was at least equal.
Tchigorin's 21. Kh1 set a neat trap for Pillsbury. The position was as follows:

Had Pillsbury here tried to grab Tchigorin's c-pawn with 21...Qxc4, he would have gotten crushed after 22. f6 g6 23. Qg5.
Pillsbury didn't fall for that one, and played the careful 21...Kh8.
The game was now approximately even. Tchigorin's next move, however, has come in for much unfair criticism.
Tchigorin played 22. Rad1. Sergeant and Watts (in their collection of games by Pillsbury) give this move a ? and state that it loses a pawn and wastes a move. The Tournament Book calls the move "premature" was says that 22. Rac1 was best. Fritz prefers 22. f6.
In fact, all of the proposed moves are fine, as was Tchigorin's 22. Rad1. This move definitely had bite to it, and Tchigorin's problems came from his failure to follow up properly.
Pillsbury took the bait with 22...Qxc4. Now, either 23. Rfe1 or 23. f6 look good and seem to lead to equal--and fascinating--chances. Tchigorin's King-side threats seem to have been worth the pawn sacrificed.
But--if the score of the game is to be believed--Tchigorin here played 23. Rde1. I do not understand this move. It not only loses time (moving the Rook he just posted on d1), it allows Pillsbury to grab another pawn with 23...Qxa2.
However--and once again if the score is to be believed--Pillsbury did not take the pawn and instead played 23...Rad8. Now, Tchigorin could have been very much back in the game with 24. f6. Instead, he played 24. Rf4, once again allowing Pillsbury to snatch the a2 pawn with 24...Qxa2. And once again, Pillsbury left the pawn untouched and played 24...Rd4.
The position was now as follows:

As Sergeant and Watts note, Tchigorin could here have simply played 25. RxR QxR 26. e6 with about equal chances.
Tchigorin, however, chose to set a nasty trap with 25. f6. Had Pillsbury played 25...gxf6 he would have been mated after 26. exf6 Rg8 27. QxR+!!
Pillsbury saw the danger and played 25...Rg8 (25...g6 would also have been good).
An interesting game thus far, but much of the excitement--and the key moment of the game--were still to come, as I will show in my next post on this game.
