Tactics on diagonals, do they exist?

I am realizing that a big weakness in my play (and my opponents too) is that we are not recognizing diagonals. I'll give a couple examples from recent games.

As you can see these diagonals pose a silent threat. Do they have themed tactics puzzles on bishops or is there a book that covers bishop diagonals?

I think the diagrams aren't working.

It seems to be working. Do others have problems seeing it?

I can see them.  I didn't comment because these two diagrams present extremely simple tactics, one missed by you, one by your opponent.  Both are well beneath your blitz rating of 1300+  So I'm not sure what they are supposed to show, or what type of comments you are expecting.

If you want to practice a certain type of problems, I know you can do that with a paid membership at chesstempo.com.  For example, you could do pin problems, which would have a lot of bishop moves.  I am not sure you can do bishop only problems, but afaik there isn't a good reason to want too really.  

Why? As you stated, these are obvious blunders in hindsight, but my eyes can't see the diagonals. So I wanted to train my brain.

Can you see any diagram here? I see starting position

Seems to be working for some, not for others. I can see the board with the positions and annotation.

Here's another example and we can see if it was just a hiccup before. In this position I saw the queen fork, but not the bishop pin. That is why I played Ne4 instead of Na4. I'll show in the diagram what I mean.

Hey I can see this one

Well, same basic question as in the original post. The actual positions don't matter. I was just wondering if there were bishop tactics I could practice. I will post the FEN for the top two.

FEN 1: r1bqnrk1/ppppbppp/8/4P3/2BQ4/2N5/PPP2PPP/R1B1K2R w KQ - 1 9

FEN 2: N1bk1bnr/pp1p1ppp/2p3q1/1B6/3pPB2/3P4/PPP2PPP/R2QK2R b KQ - 0 10

And in case you can't get the third:

FEN 3: r2k3r/1pqb2p1/p1p1pbQ1/2B5/5P2/2N5/PPP3PP/3R1RK1 w - - 5 18

Here's a funny fourth one (I was black in the game):

FEN 4: rn1r2k1/pbq2ppp/1p1bp3/1P6/P3P3/2P2N2/1B2B1PP/R2Q1RK1 w - - 1 18

Well the bh3, bh6 one in your game occurs literally all the time.  Just play, and that will get beaten into you soon.  But in general, a pin or discovered attack with a bishop isn't any different than a pin or discovered attack with a queen.  So, for the most part, the ability to practice pin or discovered attack only sets is sufficient.  Chesstempo also allows the creation of sets from only the subset of problems you got wrong in the past.  (Chess.com I've only been a premium member for 7 days so I dunno, but I don't think that stuff is offered.)    

I doubt 23. bf3 works in your last game.  23. bf3 qg5 and it seems mate is still coming.  This would be categorized as a mating tactic.  Now you are probably saying, "aha! isn't that stupid, I need help with *this* pattern, not all mating patterns".  However, consider that the tactic would work just the same with a pawn on g3.  

The maindiagonale , or a so called, golden diagonale  is like in the game "Queen" or in Germany "Dame". The owner of a golden diagonale covers half of the board, , if the diagonale isnt permanent blocked by own or opponents pawn. But a B alone is only the half truth, he needs the support of other pieces on board , F.e: Queens, btw Nimzoindian with Bb7: the keysquare  is first e4 in whites camp and later in the phase when midgame develops to endgame, f3, I practice this opening if my opponent will let me do, with  pawn f7-f5 (double control over e4 a 3rd could be reached with a N on c5 if white plays with a double pawn pawn on c3/c4 and open b-file what we see  often in Nimzoindian , btw a symbiose out of both  , A Nimzo-Queensindian So now , with f5 you can decide a few moves later f5-f4 or fxe depending on whites kingsrookposition (f1 or e1) In the case of fxe Rf8 and Bg7 covers f3, This 2 squares ( e4 and f3, are keysquares which black must cover for conterplay til late endgame. Or Retis  reception for white , in reversed Queenindians lines Ra2 Qa1 and Bb2 is a powerful cornerstanding trio , working in 3 directions , horizontal, on your first rank with Re1; diagonale on a1/g8, and vertical on a1-a8 ( sometimes i play it with black in my 10mins games) Its so flexible this trio , B and Q can move one or two steps forward on their diagonal , Ra1 moves on their path, ready for Ra2 spys for options  to move somewhere on the 2nd rank , with  rooksdoubling or Rf1 -a1 aso aso.

Super common tactics. These show up all the time.

Keep playing games, keep training your tactics, and you'll stop missing these eventually.

"I doubt 23. bf3 works in your last game."

Did you play it out? How does it NOT work? Do you prepfer Rfd1? Rfb1? Or Rfc1?

Ulbras, you are going to have to edit your post. I didn't read it. It is too joined together. What are you trying to say? Space it out.

Deranged, yes, I understand the usual comment "just play more", but there are guys like Akobian who go over such things like bishops. I thought there might be a study on bishops further back in the game in the form of tactics.

"Bishop" problems is very general I need some specification pls, those diagrams I also don't see a very obvious common theme, they are very general as well

Bishop endings isn't useful to you because endings are usually more positional than tactical

I am not talking about endgames. I am just posting an example of a GM that talked about bishops.  If you read my post and not just react to the first words, you will see I stated,

"I thought there might be a study on bishops further back in the game in the form of tactics."

Most common tactic with the Bishop, I believe, is the pin or skewer. Controlling long diagonals can be important, so should always be considered. I like to open with the Reti to fianchetto my Bishop early. The Bishop can be a very long range attacker and supporter as the board starts to thin out . . .
