What does he recommend against the Tarrasch? 3...c5 4exd Qxd5 is currently popular. It is probably easier than 3...Nf6.
In the preface to his book, Lemos indicates he's not intending to present a complete repertoire. He adds that he's focused more on showing the main ideas in the various French variations, in the hope that this allows the reader to reach playable middle games.
That said, His chapter on the Tarrasch covers both 3...c5 and 3...Nf6. The majority of the information (five games) is on 3...c5 with the black queen retreating to d7 after being hit by White's Bc4. You might recall that this ...Qd7 variation is also featured in
The French Defense Revisited. The rest of Lemos' Tarrasch chapter is two games with 3...Nf6. The first (Kudrin-Korchnoi, Beersheva 1984) covers the main line after Bd3; i.e., 1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Nfd7 5.c3 c5 6.Bd3 Nc6 7.Ne2 cxd4 8.cxd4 f6 9.exf6 Nxf6 10.Nf3 Bd6. The second game with 3...Nf6 is the well-known Reshevsky-Vaganian, Skopje 1976, which features 5.f4. Lemos apparently doesn't cover the Universal System. It's not mentioned in the games with 3...Nf6, and a possible transposition via 1.e4 e6 2.d4 d5 3.Nd2 c5 4.Ngf3 Nf6 only has 5.exd5 Nxd5 (Van der Wiel-Korchnoi, Brussels SWIFT 1986). At this point, Lemos writes, "White has a lot of options in this position, but we are not going to analyze this game from a theoretical point of view. The middle game is what we are really interested in". This statement sums up his book's content. There are going to be gaps from a theoretical standpoint, such as the lack of anything on the Universal System or the main line Winawer, as I noted in Reply #24. This approach could also be why all the games I mentioned here date from the 70s or 80s. When there's no need for up-to-date theory, older games may be well suited to illustrate important themes.
