ah, 4. g4! awesome problem.
Correct!

ok i found a line, 1. Nd4 Ke1 2. Nf3+ Ke2 3. Nxc3+ Kxf3 4. Ne2 f1=Q+ 5. Ng1+ Not sure if there are any important sidelines though.


nice way to start the day. Keep'em coming!
Correct!

Also correct

An easy one for warmup:



and then a pretty hard one (at least it was for me, was SO happy when I finally solved it)

dunno, i have visions of 1. Kh4 and later Bf3+ Bxf3 stalemate but i cannot seem to make it work. And i'm not even sure that white is aiming for a draw here.

Took me a while to figure it out!

Spoiler:
Obv the main problem with this is that it seems so unnatural to let the other side queen so you try to find every possible line to prevent it.. While in reality, 1. Kg5 e5 (or 1.. f6+ transposes) 2. h5 f6+ 3. Kf6 e4 4. h6 e3 5. h7 e2 6. h8Q e8Q and now simply 7. Qd8+ and white will exchange queens on either e5, e6, e7 or g3. Black cannot hide from that (I think).

Two not so hard (but still challenging) ones for tonight:

Hint for the second problem from post #26
Spoiler:
- R+B vs R is a draw took me good 25 minutes before I figured it out when I was solving it..

thx for the hint ykw, i think i've got it now (the hard one from your last post):

Spoiler:
1. Bf1! (needed the hint for that) Bf3 (otherwise Kh4 and the pawn falls) 2. Bg2! Rxg2 3. Rxg3! Rxg3+ 4. Kh4 and black cannot save the rook without allowing stalemate.

Really no one else is going to get these, you almost don't need the spoilers.

etude 1:
Spoiler:

etude 2: this one is really quite beautiful
Spoiler:
1.c7 Rc1 2.d6 exd6 3.Rc1! Rxc7 (or anywhere on the c-file) then 4.Rd1+ 1-0

Ah that is weird, I missed the Kf6 line in the first one but saw it in the variation where you aren't up a rook

this is one of my favourites. have posted it before, but I've spent so many hours showing it to people it is worth posting again


draw

there are some seemingly OK sidelines here, but believe me, you will know if you have found the solution.

posting some thoughts:

Spoiler:
1. b7 Nb5 is mate, and 1. Kb7 Bd5+ 2. Kc8 looks at least unlikely to help white. Giving away the pawn on g7 at this point looks also silly, so the move to refute seems to be 1. a7.

A logical line is 1. a7 Ba6+ 2. b7 Nb5 3. g8=N+ Ke8 4. Nf6+. Have to look some more

1. a7 Ba6+ 2. b7 Ne4 3. g8=N+ Ke8 4. Nf6+. And then 4 ... Nexf6 threatens mate in 2 White needs to use underpromotion/stalemate to avoid 5 a8(B) Seems like a number of possibilities after that to consider.
