Reti's Checkmate

The checkmate pattern know as Reti's Mate originates in a miniature played against none other than Saviely Tartakower. The game was played sometime in 1910 in Vienna. Both men were in their early 20s. Tartakower studied law in Geneva and Vienna; Reti came to Vienna to study mathematics. They had met in at least two tournament games prior to this game, which was a casual game played for a stake.

The mating combination itself has processors, including Morphy's Opera Game. Edward Winter's article, "Reti vs. Tartakower, Vienna 1910" is worth a look for some of these, as well as what little historical background exists. If Tartakower would have moved his king back to its starting square, the checkmate with rook and bishop would have been the same as Morphy's.

Reti,Richard -- Tartakower,Saviely [B15]
Vienna, 1910

1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 5.Qd3

This unusual move has been played a mere eight times in more than 3000 games reaching this position. This game is the earliest in MegaDatabase 2020 to feature this move. The same database contains fifteen games up to and including this one with 4...Nf6. In fact, the Caro-Kann Defense was relatively new at the time. Horatio Caro and Marcus Kann had published their analysis in 1886. Tartakower was born the following year; Reti two years after Tartakower.

Databases are incomplete. For example, we do not have all the games from the Second Trebitsch Memorial, played in Vienna in 1909-1910, which Reti won ahead of Tartakower. I have spent enough time reading old chess magazines from the last few decades of the nineteenth century to be confident that even published games played between those recognized as masters are more likely absent from databases than found there. 

Using the database as our point of reference, 5.Qd3 would be a novelty. But, there is a very good chance that Reti had seen it before.

5.Nxf6+ is played almost every time. 5.Ng3 is a distant second.

Black to move

5...e5?

Tartakower finds a clever idea that fails.

5...Nxe4 6.Qxd4 Qd5 appears equal.

5...Nbd7 6.Bd2 Nxe4 7.Qxe4 Nf6 8.Qd3 Bg4 9.f3 Be6 10.0-0-0 Qd6 11.Kb1 0-0-0 is given in an article on Chess.com by AksanAkhmad.

6.dxe5 Qa5+

6...Qxd3 seems reasonable, but is not the reason Tartakower played 5...e5. Perhaps he should have reassessed his plan. 7.Bxd3 Nxe4 (7...Ng4) 8.Bxe4 and White seems slightly better.

7.Bd2 Qxe5

It would seem that this was Tartakower's idea.

White to move

Reti's pinned knight is attacked twice.

8.0-0-0 Nxe4??

Tartakower has won a whole piece, but Reti saw further.

8...Be7 9.Nxf6+ Qxf6 (9...Bxf6 10.Re1) 10.Nf3 and White seems slightly better.

White to move

9.Qd8+! Kxd8 10.Bg5+

Tartakower resigned here, according to some accounts. Later, in his A Breviary of Chess (1937), he stated, "nothing could better illustrate the power of a double check" (as quoted by Winter, referenced above).

10...Kc7 11.Bd8# 1-0

If 10...Ke7, 11.Rd8#

The game is worthy of memorization, especially by chess teachers. It pairs nicely with the Opera Game.
