5...Qd6 variation Spanish exchange

I know that 6.Na3 and 6.d3 mainly what is played after this but I have been looking at 6.d4 exd4 7.e5 Qg6 8.Qxd4 and two other lines that start with 6.b3... Namely 6.b3 7.Bb2 8.d4 and 6.b3 Be6 7.Ba3 c5(basically forced) 8.c3 followed by d4 at some point... I have not read up on the Spanish so I don't know if these are already lines that have been explored or not but I would like some replies... I'm pretty eager to see what Tony has to say because he always seems to find some kind of refutation to my opening ideas.

That first line can be called the Spanish exchange Sawyer gambit as it leaves a pawn on c2 hanging.

Well, black seems to score well after 6 b3 Bg4 7 Bb2 f6. If you try 8 d4 (most games seem to continue 8 d3 0-0-0 with a good game for black), then Bxf3 forces you to play gxf3.

Same idea seems to work after 6 b3 Bg4 7 Ba3 c5. You have problems playing d4 because the f3 Knight can't support it.

Still all playable, I imagine and well worth trying to get out of "book" if you so desire.

I have a line that might make you look twice.

6.b3 Bg4 7.h3 h5!?

BTW - the other line 6 d4 exd4 7 e5 Qg3 8 Qxd4 looks quite reasonable. There are a few database games with it. I don't think white has enough compensation for the pawn, but he's gets lots of long term pressure. Definitely OK if you like playing gambit sort of games.
