Which black bishop would you try to get rid of in this position?

Why would black want to get rid of one of his bishops?

The vast majority of whites pawns are on the same color squares as his bishop.

To answer your question: Neither...

I really need to work on my communication skills.

I was white, I wanted to get rid of one of black's bishops. I want to get to an endgame ASAP because of the exposed position of my king and my  Qside pawn majority. I figured step one was to trade off black's most dangerous minor pieces and then hopefully queens where my control of the e-file would give me an edge.

So I can directly take the black squared bishop, or play Nd6 attacking the b pawn and the white squared bishop. I chose the second option. I have my reasons but I wanted to hear other people's first so I wouldn't taint the opinions.

Thank you very much for your analysis!

Youre very welcome.  I'm not saying its right, or even accurate.  For all i know, it might by downright HORRIBLE.  But its what i saw, and what i would do.

I was just trying to think along the lines of "How can i create duel threats?"

Wow! First post in a long time by you that was not deleted. How are you Mr. Bacon?

Interesting point. Actually I did intend to take on b7 if he moved his bishop say to g6 and then if knight was attacked I was going to move it back to c5.

Stockfish agrees with you and you're rated about 1000 points above me so I assume you're right and I'm wrong but I don't completely understand why. After all, it is a free pawn in a materially even game and creates a passed pawn.

 StockFish's refutation of my move:

16...Bg4 17.Qd3 g5 18.Ne5 Nxe5 19.Bxe5 Bxe5 20.dxe5 Qb6+ 21.Kg2 Qxb2+ 22.Kg1 Bh3 23.Qf3 f5 24.c4 Qb6+ 25.Qe3 Qc6 26.Re2 b6 27.Rc2 Rab8 28.Rb1 Bg4 29.Rf2 Kh7 30.Qa3 Ra8 31.c5 Qd5 32.cxb6 axb6 33.Qb2 Kg8 34.Qb3 Qxe5 35.Nc4 Qd5 36.Nxb6 Qxb3 37.Rxb3

So instead of retreating the bishop, black attacks and pulls my queen off of the 2nd rank where it was protecting my b pawn and then all hell breaks loose. Nd6 was a mistake. Nxf6+ was better. IMHO.

Like, if I could choose?

Immediate reaction is the light square bishop.

It's the bishop you can't easily oppose because lots of your pawns are on dark squares and you don't have a light square bishop.

I only skimmed the answers, but I didn't see this mentioned. I think it's a pretty basic and obvious answer.

Of course actual analysis may show that's impossible. I don't know. This is just an answer after looking at the position for 5-10 seconds. But if you're asking which white would rather remove, I think it's the LSB, and I think that's important enough to be worth mentioning all by itself.

(edit, nvm, I see you're asking why would black want to get rid of a bishop)

It's a rather minor victory, but it usually is considered a victory of some sort to remove your opponent's bishop pair, and usually the bishop you can't oppose.

Of course it depends on the position, and if you're giving up your best minor piece to do so then it may not be wroth it... but I think "removal of the LSB" should be... how to say it... on white's wishlist so to speak.

Spelling error fixed!

 It was obvious to everyone else what you meant, but I missed it

Because of your post, i realized i didnt spell "black" correctly.  

Thank You!

That's the same decision I came up with in the game because I just felt that the LSB was his most dangerous attacking piece. Even though, I think if I got to an endgame and we each had only 1 minor piece, his LSB would be bad for him because all of my pawns are on dark squares (except 1).

But even though I think my idea of trading off was correct, my METHOD of doing it, Nd6 was a bad move and I got lucky because my opponent protected his pawn and allowed me the trade.
