Tantale said not to post the answer so don't post the answer!
Special thanks to Tantale!
Yes, it's a "trick" puzzle :P
I will post the solution to my own puzzle:
Regarding puzzle 3#, any further progress on that one?
Switching the rooks isn't easy. For this particular maneuver, you need to find a way to block the white rook from checking the black king. But how can this be done? does white have any piece that can interfere with that check?
I give up. No use posting half-hearted solutions. I guess its ur turn shoopi...
Alright. The really tricky trick is to use the white king in order to switch up the rooks - white rook getting to e2 (you need the white king to prevent the rook from checking the black king), then the black rook gets behind it, then the white rook gets back and viola! the switch is complete. Proof game below (watch move 51 onward for the critical maneuver):
New positions coming up.
First one is a composition by einstein_69101, second one is a composition by myself. Possible or impossible?
Second one is impossible. How could 2 rooks be on the 1st rank adjacent?
Yeah, but that's not the final position expressed in the puzzle originally, so still impossible.
Puzzle 2 is indeed impossible see position below
After Black plays gxh2 in that setup (the only way to get a promoted Rook on g1, White is stuck: no pawns can be pushed to alter the position and the remaining piece is pinned. Now bite me and prove me wrong as always
Hm... What if there was another knight on f1, like this:
Yes but in order for the c7-pawn to reach h2 White had to sacrifice 5 mens (excluding Bishops since they could never get out of that pawn formation), two Rooks, a Queen, a Knight and the h-pawn. I would liked a scenario like this however...
The first position in #151 is possible:
and viola! the switch is complete.
Still awaiting sentence for the second puzzle... good luck.
The second position is also possible:
Congratulations to both of you!
More positions coming up.
which of these positions is legal? (composed by cobra91):
here's another one, black can still castle on both sides but that doesn't really matter
is it too hard or is it too easy that nobody wants to answer?
