MatPlus.Net Forum General Die Hard (another free-for-all construction)

### Die Hard (another free-for-all construction)

Construct a "dead" position (drawn even with worst help play).
A capture should be possible still after arbitrarily long play.
(E.g. Kh6 Rg8 - Kh8 is dead, but the capture will follow now.)
Ignoring, of course, the fact that you can't play - it's dead -
and the 50 move rule too.

(I already have a position, but I'm not 100% sure it's legal.)

Hauke

Does not any 4-unit position with white and black bishop on the same color meet your requirement? Or should the capture be possible although the opposite side defends against that? Something like wKe4 - bKa8 sSh1 and capture in three moves?

Nono, you're right, I was just stupid, I'm always thinking
too complicated :-)
With at least 1 pawn [and 1 possible capture each]:
Kh1 Pg2 Pg3 Pg5 Bh4 - Kh8 [Pg7] Pg6 Pg4 Bh5
If you switch the kings, you also have an example for
"draw with any help play, but still a capture can be forced
against opponent play". (Since the king can shoulder off
his opponent, the capture still can be delayed ad infinitum.)

Hauke

Here’s the longest direct one I have been able to create so far, Hauke. A little late to the party, ey?

Capture Bf8 In 26 Moves
(= 10+10 )

Nobody called Jarosch a snail either, so
go forth and multiply the move count ;-)

Will do Hauke!

Here’s a another helping for you. ;)

BTM, Help-Capture Pg7 In 23 Moves
(= 10+10 )

Of course, an illegal position always allows for a longer problem.

Capture Bh2 In 64 Moves
(= 10+14 )

Bh2->f2 gains a few moves?!

You’re right Hauke. Shift Bh2->f2 for 70 moves. It ends as follows: 63. Bc7 Be1 64. Kg1 Bd2 65. Kf1 Bc1 66. Ke1 Bb2 67. Kd1 Ba1 68. Kc1 Bb2+ 69. Kb1 Bc1 70. Kxc1.

Normally it isn't my style since the OTB in me
cries for mercy...

(= 10+19 )

Some more moves can be added with bPh5.

No, since I (for what silly reasons ever) wanted the position
to be dead, otherwise I'd suggest something like this:

(= 2+9 )

I'm too lazy to add all the black pawns from a-h except g,
and even Rewan would need days to compute the moves until
capture of Bg1 since the white bishop can try to massacre
them from behind to speed up the process.
