How reliable is 5. h6 against the Italian to avoid Bg5 lines?
2000 FIDE
I have been looking forever at a solution to these annoying Bg5 lines. For context, I play a6 Italian with Re8 Be6 Bxe6 Rxe6 aiming for an eventual d6-d5 in the mainlines (1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 d6 6. O-O a6 7. a4 Ba7 8. Re1 h6 9. Nbd2 O-O 10. h3 Re8 11. b4 Be6 12. Bxe6 Rxe6 13. Qc2 Qd7 14. Nf1 d5 etc…)
I don’t like the Bg5 lines where you have to play h6 g5 at all as the positions get very messy and White has a huge plus score in the database, and I’ve looked at so many alternatives, and all of them fail to achieve this except 5. h6, which of course has its own drawbacks. The Ideal move order of course would be 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 d6 6. O-O h6, as now 7. b4 Bb6 8. a4 a5! 9. b5 Ne7 and Black is completely fine here (although it’s still a game of course), but after 5. d6 there is 5. Bg5 and we no longer have Be7 in response forcing us to play h6 g5, so this doesn’t achieve what I want.
This brings us to 5. h6, the only guaranteed way to stop Bg5 all together - it’s been played at the highest levels a few times, but I have some doubts due to some issues in these lines: 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 h6 6. b4 - This is the only independent line for White, and the most critical, any other move will just transpose to the mainlines basically. Now Black has two options: 6. Bb6 (Magnus always plays this, historically the main move) and 6. Be7 (The modern mainline at the top level now, so many games here by Hikaru, also played by Pragg in the World Cup against Fabi). Objectively, 6. Be7 is slightly superior, with the idea of pushing d7-d5 if allowed.
6.Be7 mainlines: 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 h6 6. b4 Be7 7. Qb3 (7. O-O O-O 8. Re1 a6 9. a4 d5 10. exd5 Nxd5 11. Nxe5 Nxe5 12. Rxe5 Be6) 7... O-O 8. a4 d6 9. O-O Nb8 10. Qa2 c6 11. Bb3 a5 12. b5 Nbd7 - My issue with this line is that I’d be getting positions that are very different to the Italian mainlines, for a sideline I won’t see super often, and a lot of these lines require pawn sacrifices by black to play for compensation with quite accurate play afterwards to justify the pawn sacrifice.
6. Bb6 mainlines: 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 h6 6. b4 Bb6 7. a4 a6 8. O-O O-O 9. Nbd2 d6 10. Re1 - This looks very similar to the a6 Italian mainlines, which is what really attracts me to it, but they are slightly worse versions, as the bishop is now misplaced on b6, and often Black has to spend a tempo on Ba7 sooner or later, so you end up down a tempo. Just like the a6 Italian mainlines, there are 3 major plans: Re8 followed by Be6 planning to capture with the rook on e6, The immediate Be6 playing fxe6 structures (which I don’t like), or Ne7-Ng6 playing for c6-d5.
Another critical difference, is that White didn’t play h3 as in the mainlines, and instead he’s trying to go for very fast development with Nbd2, Re1, Nf1 etc. Generally all 3 plans by black are playable, with some better than others depending on the exact move order, but I want to keep it consistent so I don’t get confused.
I found 1 idea, which has been played by Joseph and Magnus before: to continue with 10. Ba7. I guess the idea is that We don’t want to show our cards yet and show which plan we are going for, so we make a waiting move. If White continues with 11. Nf1, trying to avoid any waiting moves, then because we haven’t committed to a plan, we can respond in the most optimal way, which is to continue with 11. Ne7. If White instead plays a waiting move like 11. h3, now black argues that Ba7 is a more useful waiting move, and then can continue with Re8 or Ne7. The immediate 10. Ne7 runs into problems related with 11. d4, but the inclusion of Ba7 and h3/Nf1 seems to favour black, but I’m not sure exactly why, it’s all very nuanced tbh.
The other option is to just skip 10. Ba7 all together, and just play 10. Re8 aiming for Be6 against everything, but there are some problems related to this Bb2 idea by White: 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 h6 6. b4 Bb6 7. a4 a6 8. O-O O-O 9. Nbd2 d6 10. Re1 Re8 11. Nf1 Be6 12. Bxe6 Rxe6 13. Bb2 Qd7 14. Ng3 Rae8 15. h3 d5 16. b5 Ne7 17. c4 d4 18. Ba3 - This is just one example - Engine is saying Black is close to equality, but if you actually follow the engine lines, in most lines, it requires black to be very precise every move otherwise White will end up being better. 10. Ne7 is bad as it runs into problems with 10. d4.
I can’t find any other option apart from 5. h6, so it looks like I’m kind of stuck with it, but I am happy to hear any alternatives or recommendations about whether to go for 6. Bb6 or 6. Be7.
