Wow you learn something new every day!!!!

did you know that in this position (white to move) white can force a win? previously, the position was thought to be drawn. But German grandmaster Steckner proved it was winning for white in 2003 (Recent!) !!

while in this position (black to move, Dautov)



he can force a draw?

With white to move, he wins with 1. Kd4! With complications that you won't see even in the najdorf and dragon combined. 1...Rxf2 2.Kc4!! (2.Kc5 draws, but I don't know why!)

While with black to move, he draws with 1...Ra4!! 2.Kd3 g5!!

And in the end, black reaches this position (white to move):

If you shifted the rook and black king one file to the right, white would be winning! But black draws because his king is close enough by one tempo. 

I have to study this stuff a bit more. 

colorfulcake

what i always thought those positions were drawn

sndeww

well i did too

Black has another way to draw, based on having his king on f5, playing f6, and then running to h3.

john did good videos on this with techniques to either win or draw them

ok this is crazy stuff

I know the ending is drawn because for rook pawn lucena the enemy king has to be cut off by three or more files but to get to that position is... hard

I've recently decided to specialize in winning opposite colored bishops endgames after looking at a few insane wins

2021blitzgrind

This is actually insane and probably fundamentally changes how we look at such endgames up a pawn 

Still would take really high skill to convert though 

Although (human) opponent wouldn't necessarily play perfectly

sndeww

Of course not, but god damn

the trouble with endgames though is you need to calculate insanely deep to win

which is possible since they're not as complex (most of the time) but still

hi this endgame is basically borderline winning for white

Or rather 

In endgame the material is reduced enough you can calculate with a variable amount of certanity whether a line absolutely wins, loses, or draws

I could do an entire lesson on this one position, in the book I have the author took thirty pages to explain

After reading this post I realized I knew absolutely 0 about endgames OR chess

And thus why we aren't 2000  

Because we just play mindlessly without actually learning ig

I thought I was good at endgames until yesterday when I read the chapter on this position

then i realized i was dog

And then you realize I've actually never seriously studied endgames 

Just intuition and puzzles 

Now we wonder why I fail to convert materially balanced endgames that are winning (like that game you annotated for me)

Oh what I thought that was a draw

actually I think even if the black king's planted on d7 white wins with bxe6! deflecting the king and letting white's king support the a-pawn which forces black to trade of his bishop for it

then the k+p endgame is easily winning because e5 and it's a protected passer while black can't make a passer of his own

the best winning plan is pushing e5, then f5. This gives white a passed e pawn, which he uses to deflect the black king so that he can run to the queenside. After winning the bishop for he a pawn, black is LOSING because he has both g and h pawns. If one of them were gone, the position would be drawn.

Oh no it's an endgame
