Chessbase India posts some nice studies every day. They are quite fun and good for training, but not too many people end up seeing them (which is kind of sad, the subtle solutions are often more beautiful than popular violent games). I’ll be reposting their tweets every day in this thread, with credit to the composers.

Hey Zelgiusfan5000,

It's great to see that you love the puzzles from ChessBase India! I agree that they are really nice - I usually get them wrong, unless I spend a long time trying to solve them (which is rare).

I have a Facebook group, Chess Endgame Studies and Compositions (https://www.facebook.com/groups/544412592978833/), where Satanick Mukurthy (a big chess problem enthusiast) shares these puzzles each day (and there are many other nice studies and compositions each day, too :) ). Anyway, I look forward to seeing you there, so that you can join in the discussion!

Thanks a lot Max, I had no idea a large community that shares these regularly existed. I’ve requested to join and look forward to solving them, although you probably won’t see me discussing much.

I think: black king has no moves, all that required is to give a successful check. d8=Q is tempting to threaten 2. Qa5+ and Qg5+, but 1... c1=Q prevents it being mate in 3.
I think 1.Rg1 works. 1...c1=Q (forced) 2.d8=Q and now blacks onle check 2...Qg5 is met with 3.Qxg5#. Otherwise black has no other move to stop the dual queen threats of Qa5 and Qg5.

Ah yes very nice, black can underpromote to knight, threatening 2... Nxd3 and avoiding mate next move if white queens. So needed is 1.Re1 c1=N 2. d8=N Nxd3 3.Bxb3#

Funny zugswang

I wouldn't really consider this to be a zugzwang, but 1.Ndc5 is threatening 2 mates and depending on what piece black promotes to after 1...a1, white will either mate with Nd7-c5-a6-b4#, or Nd7-c5-b3xd4#. 1.Qe3 threatening 2.Qd2# is also interesting with the point of 1...exd3 2.d4# but 1...f2+ spoils the fun and it's mate in 4 not 3.

:hmm: not sure what problem we're trying to solve here. Looks like white has given up R+3P for N+2P. Kingside looks a little soft if black can get in ...Rh1 or ...Rh2 but just Nf3 white doesn't seem to be in immediate peril.
Or is this another one where we have to re-contruct the 7 moves?

By Aleksandr Kuzovkov

This one was quite interesting in that white has several promising first moves, but black can seem to thwart them all.
1.Qa2 threatening both Qc4# and Qd5# can be met with ...e2+ and ...Be6 stopping white from mating on the third move.
1.Qc2 threatening both Qd3# or Qe4# can be met with ...Be6 and with e2+ again forestalls mate.
1.Qe2 threatening both Qd3# and Qc4# is met by ...Bb5 and again e2+ prevents mate by the 3rd move.
1.Qh1 threatening both Qe4# and Qd5# black has Bc6 and e2+.

However white can first play 1.Ke1! and now black has no way to pass and keep an eye on all those defences. Eg if 1...Bxe8 Qe2 and black can no longer play ...Bxf5 and stop the mate threats. Likewise 1.Ke1 Bxf5 2.Qe2 mating. If black instead passes with the other bishop, Eg 1.Ke1 Bxa3 2.Qc2 and now white also threatens mate on c3. The threats cannot all be met.

One piece here is extremely important. Try to figure out why

Looks like the white king is very important since it blocks the e-pawn and that prevents all the black pieces from unravelling. Example line 1.d6+ dxe6 2.Na3+ Kb3 3.dxe7 Kxa3 4.e8=Q and I don't think white has anything better than harrassing the black king, with a draw. If white ever tries to bring the king into the fray with Kd2, black can go e1=Q ++ and his pieces will come out pretty quickly, winning.

Zelgiusfan5000
27-02-2020, 10:17 PM
There is still a way to kill with just the queen, if the king somehow gets into an inconvenient hole. You can stalemate the king, forcing the pawns to move, you should take some to create the hole, then later on get the king out of a1, eventually moving him over to a8, then h8. Now there is an idea to force the king down the board for the execution, once you find it you should see what the problem could be, which shows you the importance of a certain piece.

Not so difficult, but don’t stop calculating until you’re certain black is lost

This time I’ll give a different kind of problem.
Black has three pawns and a king, white has only a king. You can place all the pieces wherever you like, except the pawns cannot be on the same file. Try to set up a position where it’s black to move, but white can make a draw

I'm assuming none of the pawns can be on the same file as each other, otherwise it's too easy. Interesting puzzle. (Don't have the answer yet.)

If it's white to move, something like this works:

8/7p/8/8/8/5p2/3p4/k2K4 w - - 0 1

Not sure how to do it with black to move.

This is a near miss:

7k/7p/8/8/8/3pKp2/8/8 b - - 0 1

Black wins only by 1...f2 2.Kxf2 h5 - everything else is a draw. But putting the king in the way of the h-pawn allows it to save the f-pawn.

I haven't ruled out the answer being "you can't".

It’s fairly clear a pawn must be on the h file since you cannot capture all three. White will need at least 3 moves to capture both pawns, and if black can play h5, h4, h3, the second pawn captured must be on f3 to control h1. Since putting it there doesn’t work, it’s safe to assume that you must somehow prevent/interrupt him from pushing the pawn to h3

This is another very near miss

7k/7p/8/8/4p3/6p1/6K1/8 b - - 0 1

White captures both the g and e pawns but meanwhile black has Kg7-Kg6-Kh5-Kg4 and wins. Could put the king on a8 instead, but then it saves the e-pawn.

Solved! Thankyou, that was quite difficult and rewarding.

Hint in white text:

One of my near misses is very near indeed.

I've also found a second solution (not a mirror) that is only very slightly different to the first one.

I can’t seem to find a second solution, king has only one square that can’t protect e4 and it doesn’t look like the pawns have any alternative.

Solutions in white text (verified by tablebase):

Black pawns e4, g3, h6 Black king h8. White king can be either g2 or h3

Ah I get it now. With the pawn on h6 rather than h7, it matters in the line with white taking the oppostiion on g4-g6, when black has neither the waiting h7-h6 or Kh6. Very nice.

Most moves are relatively easy to find, but some precision is needed for the finishing blow. Ideally, you’d like to play ba5 when black’s king is on c4, there isn’t any other way to win the c pawn. Black’s king also needs to be able to step inside the h pawn’s ‘box’ whenever you play bh2
