What's the point of b3? You are no closer to castling and the pawn on e5 is easy to defend. White piddles away his opening momentum.

White could still castle a bit later, and perhaps even reserve the possibiliy of castling queenside. The bishop seems like it could be powerful later, and it also helps support a d4 push, trying to open its lines onto the black kingside.
I'm sure this opening is inferior to things like the spanish/italian/scotch , but is it at least equal or interesing for white?

White can get the pawn back after 3...Nf6 4.Bb2.
I would go for 3...Bc5 4.Bb2 d6 trying to play against the bishop.
5.d4 ed 6.Nxd4 Nxd4 7.Bxd4 Bxd4 8.Qxd4 Nf6 is a Philidor with Black having traded the bad bishop. But there are still some pieces on the board.
5.c3 I don't like because of 5...Qe7 6.d4 Bb6 when the bishop is stuck behind pawns
i think the biggest weakness is that you give up a tempo playing b3 to open a line for the bishop, but as soon as you move the knight to c3 (which you will want to do at some point in the opening) the bishop will be blocked and those 2 moves would have been wasted. For that reason I would never play those moves but I'm sure if you play the opening enough you might be able to develop a solid strategy that would at least be effective against comparible players to you. If you do than post the games here

Thanks for all the advice, I now see this opening is clearly inferior to others if black gets in an early d5. Still, I would be interested in playing it to develop my own ideas with it, much more sound than other openings I have thought of...
And I was thinking to avoid putting the knight on c3, perhaps maybe d2 or maybe even a3, planning to reroute it depending on the position.
Hi Bereng--if you're not familiar with it, check out the Konstantinopolsky Opening (1. e4 e5 2. Nf3 Nc6 3. g3) and contrast it with your system. g3 instead of b3 is still uncommon, but has a fair reputation--it can lead to setups along the lines of a King's Indian Attack, Sicilian Grand Prix, etc. b3 isn't a mistake, but it just makes less sense; e5 is easily defended with ...d6 and f4 is a more logical break against ...e5 than c4 is. That's why the b3 move is better combined with queenside systems like 1. c4. White already controls d4, so Bb2 doesn't add much over Be3, etc.

Aschere, in the last position you posted is 8.d3 tacically possible? 8...Nxf2 would be a disaster for black, and after 8... Bf2 9. Kd8 it seems black may lose a piece, so he must retreat? Or could he castle and try to use a pin on the bishop? There would also be the g7 pawn to worry about, anyone sure what is best?

That posistion could be avoided by white,but after 1. e4 e5 2. Nf3 Nc6 3.b3 Nf6 4. Bb2 Nxe4 white could perhaps proceed with an immediate d3, kicking the knight back like in a petrov, and then regain the pawn.
But even in that position, what about 8.d4 , it seems good. And is 8.f3 so bad? Tactically doesn't it accomplish something, as the knight can't move and g7 is hanging?

I had the same idea, was also playing like that , and was effective..because opponents dont defended e pawn correctly , maybe.. but now i know b3 is better

the number of times a short queenside fianchetto (no, a6-b5 like in some ruy lopez defenses) is harmonious with e4 or e5 for black is miniscule. they just dont sync well with another for many not that easy to explain reasons

Hello, I've recently been thinking of the opening 1.e4 e5 2.Nf3 Nc6 3.b3!? , which seems to me interesing, and have found near nothing about it online.
I suspect 3... Nf6 is blacks best response, after which it is possible to fianchetto the bishop and counterattack the pawn.
I'm not expert, so can anyone suggest reasonable lines/strategies/ideas for this opening, for either side? It seems to me at least equal for white, and perhaps a god way to get 'out of book'.
It would also be cool if people would try this opening and post their games with it. Any thoughts are appreciated!
