Sorry 10. Qd7

So the analysis told you it’s a mistake? If so, they always provide the line the computer recommends as the preferred reply, study the reply and find out why. Just from looking at it briefly QD7 looks okay, as you are threatening Nd4 next. Another typical way to break a pin here might be to move your knight on f6 to d7 to break the pin and fee up the queens knight for d 4 or allowing an f pawn push too

Running it through analysis the engine likes ...g6, then ...Bg7 saying that it gives you advantage. I personally would have headed in the direction of my comment above, but I’m no master level player. The Bishop on g7 would be at least temporarily blocked by the e5 pawn, but it looks like white would seek to break in the center soon anyway, so then that bishop becomes a solid piece.

Hi. Yes instead of breaking the pin, the computer suggests this 10....a5 

11. b4 would make sense and pin is automatically removed (as bxa5 would be followed by Rxa5) and the queen has to retreat

I checked your move for pin removal, the computer treats higher than Qd7. I can see why it is a better move than Qd7.

But still Qd7 makes (-.8) to (-.3), slightly perplexed at how machines evaluates.

It's not a mistake. Looks fine to me. Check the analysis again. 

The correct annotation is:

10. gxf3 (for White's move)

10...Qd7 (for Black's move)

Thanks, everyone..Gargraves g6, Bg7 looks slightly discomforting for me, opening king's pawns! I am at a 1000 rating, so excuse me for that happy.png I want to castle on that side by Be7 in few moves.

But I liked your alternate move for the knight, goes well with my thought process. Long way to go. Thanks

Ransome 1..The computer considers Qd7 as an inaccuracy. It's not a mistake, my bad!

I think computer is worried about king's safety, maybe. It wants to castle as quickly as possible since the position has opened up a lot. And, the reason it’s suggesting g6 and developing the bishop into fianchetto cause 1) centre pawns are in dark squares.So dark Bishop has less mobility from that diagonal  2) opponent has an open file for the rook on king side.

Correct Vincidroid...understood! Thanks
