Mate with a knight and bishop?

Yes - that post appears to be the only one in the entire forum with upvotes.
Perhaps its because when people read my post - they clicked the upvote to see what happens ! 
But there's a 'sort' button at the beginning.
I'll try that now.

forums --> topics --> threads --> pages.

we're on page 3 of a knight & bishop mate thread.

There's 'sort by relevance' at the beginning - my post is now at the top on that.
I did delete some of my posts.  I do that if they prove to be too inaccurate.
I'll have to delete a couple more.
Too far off the mark.  Speculation was useful temporarily but I don't want to mislead readers.

Note that the 'sort by relevance' moves post 1 off the top.
Maybe they should have made it so that the opening post is always on top.

Yes.  You're right.
I'm wondering if they should have made it with keeping post 1 on top.
But - that could have drawbacks too.  

that would be a good suggestion to make.

I was thinking that but then thought some more 
and realized that if people who have hit 'newest' or 'relevance' and still see post 1 at the top they might be disappointed or think the feature isn't working.
So this looks like a very good idea.
People can get a better sense of the thread by hitting newest as well as oldest.
As to how 'relevance' will work out - time will tell.

It's interesting that you say this, as I think there is an element of truth in this.

It is not hugely difficult (relatively speaking) to force the king to the edge of the board with the bishop and knight, when there are two well known methods to force the king to the 'right' corner (Deletang's triangles and the W method), which makes it a bit easier to learn.

With the Q v R ending there are not as many resources saying how to win with the queen. There is the well known Philidor position in this ending (which is a win with either side to move, as Black must separate the king and rook, allowing them to be forked in a few moves), but not a lot of resources saying how to reach the Philidor position. Often defenders will keep their king and rook close together to avoid any forks.

On a brighter side, even grandmasters have messed up these endings...

Rook and knight vs rook is considered easier to draw compared to rook and bishop vs rook. The defending side is normally fine unless their king is in a corner.

'derek grimmell' on youtube for Q vs R.

Yes - and I'm thinking grandmasters have failed to win with rook and bishop versus rook - more than with Queen versus rook.  
Defenders in Q versus rook must also avoid skewers and pins as well as forks.  But the skewers and pins mostly wont work if the King and rook stay close together.

stalemate traps & 50-move draws galore in Q vs R if you don't understand it well.

Rook and knight versus rook I would think is a book draw unless the side with the knight has something tactically immediate. 
The knight simply cannot support the rook from a distance in a way that the bishop can.
And in N+B versus lone King - the bishop does more of the 'work' than the knight.
Consider that the two bishops ending is a book win that's not that difficult -
but the two knights ending is a book draw unless the defender blunders or there's something like an immediate mate.
Perhaps there are positions with 2 knights and nothing else where the defending King is on move but can't draw.  I haven't checked on the net.

 

Yes - most of the draws are probably 50 movers.

There are some well known drawing defenses in the rook and bishop vs rook ending, but these require accurate play, when sometimes only one move draws.

Yes - like with Queen versus rook (a book win) - the defender might blunder anyway and make it easier.
With rook and bishop versus rook - many of the positions are in fact book draws - but again - the defender might blunder.
And even in the book wins - you'd want him to blunder perchance !
I can hardly recall the theory at all.

If the king and queen are poorly placed, the rook can sometimes draw by perpetual check (due to pin/skewer ideas). However, drawing by the 50 move rule (as you have pointed out) is much more likely.

I agree.  Technically the plus side can blunder too - but the pressure is on the defender.  Usually.  Very strong players often pull 'swindles' - but it would be extra-rare that they would be defending such positions - more often its the weaker player that's already cooked well done.

which means its a draw anyway.  
Is it technically drawn to begin with because ... ?
well better to ask that if the white king is somewhere particular.  

Rook and knight versus Queen I would think is usually a draw ?
Not sure - perhaps computers have found otherwise.  

Knight is the most annoying piece when it comes to fork
