I think you mean 1...e5. Pushing the pawn to b5 is theoretically more in the spirit of the Sokolsky, gaining more queenside space. I played 1.b4 e5 2.b5 once in an official game and i won it against an opponent with 200 Elo points more than me, and i'm planning to do it more in the near future. I have 2 books on the Sokolsky ("play 1.b4 !" by Lapshun and Conticello and "1.b4 Theory and Practice of the Sokolsky Opening" by Konikowski and Soszynski) and strangely enough neither of them has a game with 1.b4 e5 2.b5 or even mentions this move order. I found however an annotated corresp. game with 2.b5 here http://www.chesscafe.com/text/kibitz86.pdf between T.M. Whiteside and T. Harding. When i put 1.b4 e5 in Shredder12 it even gives 2.b5 as the second best move. I think under master level 1.b4 is as good as any other opening because the objectively slightly worse position for white is compensated by the experience&knowledge of the Sokolsky player and the fact that he feels comfortable with it.
Orangutan? 1.b4 d5, 2.b5

Both e5 and d5 are respected answers to Polish.

Why play b5 when you can play Bb2?
It's a slippery slope you're on. Picking a second rate first move, I can understand. But following it up with a second rate second move....where does the madness end?

I played a game with this opening earlier today. I think 1...e5 was the move I made, and it continued 2. b5. Personally I think b5 should be played later on when it actually proves useful.
I know both 1...d5 and 1...e5 are good replies to 1.b4 but in the original post by fawe4 he was mixing up both replies, because it would be really difficult to attack the opponent's e-pawn with 2.Bb2 after he played 1...d5. 2.b5 is a possible answer against 1...e5 but against 1...d5 it wouldn't make much sense ?! After 1...d5 white's push to b5 should or could be played later.

I always play 2.b5, 3.bB2, 4.b6. At that point everything turns into a flanking and keep that knight in b8. Usually the opponent tries to trade c7, so I reinforce it that possition with a4 and c4, even I play c3 to allow the cover of the bishop. The opponent is forced to a KS castle, so anothe play I use commonly is f4 - Nf3 and put my Bishop in e2 or c4 (the later is a very strong move, my first option if I can put it there). If the opponent comits the mistake of taking c4 or trade it, no problem, I have a Rook covering that line...
Some games I've won using that opening, and some variations.

I love to fool around with Orangutan opening (1.b4, also called Polish opening)and people usually respond with 1 ...d5. Now, pretty much every logical direction of going forward should be protecting your own b pawn or 2.Bb2 to attack opponents e pawn, but from my experience playing it, anything like that will make it difficult later, so I play 2.b5. It looks a dumb move, but I somehow have an easyer game than against any other responce to b4. Offcourse with keeping in mind that 1.b4 initially is not the best thing to do, but like I said, I love to fool around.
So am I missing something? Some trap later on? Or is it actually a decent way of playing.
