On Tueday's evening I will play against strong Master Candidate in 3rd round of club championship. He usually plays 1. Nf3 followed with 2. b3. And then may be 3. Bb2 or 3. e3 or some transposition that lead to position with fianchettoed b2 bishop, knight on f3 and pawns on c4 and d4 (usually it is pushed later).

How should I play on first 5-7 moves? 1... c5, 2... d5 and 3... Nc6 ? What if white will play Bb5 after some prepare? I have base with 1.7 million of games and an opening book (I mean paper book) but this opening is quite rare and book and base don' t help as I want.

Does anybody know specifics of this opening? Does anybody play it? Should I search for some example games I don't know?

Try c6 d5 Bf5 Bd6 a6. Soltis reccomends it and i almost always play it as black . I belive i have played 1.b4 as my first move in chess.com it has almost the same formation and the only flaw to this move is the central squares. The opening becomes solid once it  gets the following formation Bb2 d4 e3 c4 Nf3 Nbd2 a3 Qc2.Or you could follow Capablanca's advice... "When faced with an unkown opening, put your pieces out and develop quickly". And as for a freindly advice... "don't underestimate it"Good luck

The opening explorer gives good odds with 2...c5  3...d5,  it also gives good odds if you get your d-pawn to d4 first.

as for me I can't help you.

Good Luck

Thanks for answers. I will play this

What is your plan after 6.f4 followed by g3 Bg2 Nd2 00 c4 Bd3 f5...i have the feeling you opponent will force you to create an isolated pawn.

What is Bg2 and then without any bishop mivement Bd3? And after all black can put d7-knight on b6 to have an extra piece defence on d5.

See this game.

Sorry my mistake. I was pertaining to the possible moves by white i mean the sequence that white might play namely 6.f4 then g3 then Bg2 then 00 then c4 or 6.f4 then Bd3 followed by f5 (all white moves).  The position based on the sequence of moves you just showed me now does produced and isolated pawn what if white forces you on 20.Qd4  how do you plan to play the imbalance of kinights vs bishops? the position is open his bishops takes advantage of the diagonals. But if you are well versed in handling knights vs bishops this would not be a problem. He might try giving you his a-pawn then challenging both the b-pawn and the d-pawn becasue of his two bishops.I find whites f4 pawn a grimace to black.

And about my yesterday's game - I lost. Here is the game.
