Move 5 and this position was never played by Masters?

Greetings. My name is PLAYER. I am here because I found a pretty unusual situation:

Let me explain: 

"I was comfortably playing a Chess game in Roblox. After I won it and went to analyze it, I found out that, from move 5, no Master played the position."

   Now, the question... Is this a coincidence or is there a line that arises from the position to which Masters prefer to avoid?

because the move makes no sense. When you play Bb5, you are supposed to take and only if you are comfortable with that should you play bb5 to begin with . Whites threat is d5 so black must either play a6 or do a dumb time wasting move like bd7. If you know black will go a6, you must either play Bxc6 or retreat like in a ruy lopez to a4. Thing is, after the natural b5 bb3, after e6 the bishop looks quite passive on b3. 

be2 is rational but its an amateur move because moving bb5 when you were fine with be2 means you gave your opponent a useful pawn move (a6) for no reason. This is why they are no master games.

 

When there are only 5 moves and it has never been played, that means there are bad moves for one or both. Here it is true that White is somewhat better, but he made not so good moves, Black played moves to have a bad opening (Nc6-Bg4-a6).

Anyone who has reviewed 2...Nc6 here before, knows that 3.d5 is very strong although you could gladly play another move, but 4.Bb5 misses a good chance of a well-known trap against the Scandinavian defense which works here too .
If 4.d5 should not play 4...Ne5? and if you have solved certain tactical exercises from certain tactics books, you may already see the move, the difference is in the Scandinavian there is no pawn on d6, but here White also wins, although not a whole piece is a winning advantage. 5.Nxe5!! Bxd1 6.Bb5+ c6 7.dxc6 a6 8.c7+ axb5 9.cxd8+ Rxd8 10.Nxf7 (in Scandinavia there is no pawn on d6, so White captures on d1 and the knight on e5 is not lost). In the Scandinavian defense it goes like this: 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd8 4.Nf3 Bg4 5.d4 Nc6 6.d5 Ne5?? .

4.Bb5 is not that conceptually so bad, but 4.d5 is much better, what doesn't make much sense is going back with 5.Be2 . After 4.d5 since you can't 4...Ne5 the knight has to go back to b8, which is bad in this case, the bishop on g4 doesn't press anything unaided, so it feels useless there. If Bxf3 the absence of the queen bishop and white pawns on d5-e4 makes it easy to control the light squares

In Gm Christiansen Bauer’s book “The Modernized Nimzowitsch Defense”, he gives the Bb5 variation as the most challenging.

And indeed, although white would get an advantage with 3.d5, black can play Nb8 when there is still plenty of life in the position. Besides, the Nimzowitsch player is probably aiming for those sort of positions at least half the time.

So I have never been a fan of playing d5, and am always pleased to see it as black.

In my database over 9 million games Nimzowitsch only played 1...d6 once against e4 and after 2.d4 he answered 2.Nf6 , he didn't even take the queen's knight to c6 , he played it on d7. Also the problem is not to play Nb8 after being attacked, but that Bg4 is useless or is exchanged in favor of White no matter what happens. In practice there are about 259 games with 4.Bb5, with 4.d5 149 games but the average rating of those who played this move is much higher. That is to say that the higher rated players tend to intuit that 4.d5 is better here.

With 4.d5 there are 97 wins and 45 losses, with 4.Bb5 there are 79 wins and 80 losses; In practice d5 is much better and gives better results, 4.Bb5 is not bad but it is inferior to 4.d5. In practice the vast majority of games against 4.Bb5 answer 4...a6 and although 5.Bxc6 is the best there are only 65 wins against 53 losses, which means that in practice it is easier to take advantage of 4. d5.

There are 73 games where black makes a mistake and plays 4...Ne5, in only 29 games they made 5.Nxe5!! and they won almost every game and some draws and losses. Against 7...Qa5+ (the continuation where White gets the queen back later) wins 18 games, loses 5 and three draws, 5.Nxe5 is objectively winning and easy to win in practice. In the games that White does not play 5.Nxe5 he wins 23 and loses 13, which means that White wins almost twice as many games even if he does not know the trap. Against 4.d5 you may like to be forced to retreat 4...Nb8, but in this case it's not business as usual, chess is not only pawn structure the Bg4 difference is a problem, when you can't play Ne5, the bishop will have to exchange or retreat with great advantage for white no matter what you do.

it just loses a tempo.
