Puzzle 1010 - Admin :: Comments

Post on Sat Dec 07, 2013 8:05 am  Agua75

I must say this one is more of a challenge, no wonder it is still unsolved Smile.

I have tried different moves and I'm still not seeing a overall win.

The move with most options still producing a win for White that I've seen is :

1. fg5 hh6 2. fg7 ?. Most moves I see after for black looks like a lose, except if black responds with :

    hg5 3. gh8 fe4 4. hf6 fe3 5. fh4 fe7 6. hd8 ef2 7. ge3 df2 and I see no win for white Sad

    I want help with this one

Here it is Sir Jake :

1. gh4 cd2 2. ce3 df2 3. ge3 and the follow up moves for black are :
    hg1 4. fe5 gd4 5. ec3 cb4 6. cd4 ba3 7. de5 ab2 8. ed6 ba1 9. fe7 and white will win with 4 pieces against 1 as 3 are across the Mother line and are all potential kings.
 If fe7 4. fd8 hg1 5. de7 gd4 6. ea3 and white wins with 4 pieces against 1.
 If cb4 4. ac3 hg1 5. cd4 gh2 6. fg5 he5 (if hf4 7. gh6 fc1 or fd2 8. fg7 and white wins with 4 pieces against 2). 7. dc5 eg7 8. cd6 gh6 9. ef4 fg7 10. fe5 he3 11. dc7 ed2 (if eg1 12. cb8 and white move to win with 3 kings) 11. cd8 as white proceed to win with 3 kings by again protecting piece at e5 from being eaten.

Again Agua - you do not think "kill", you generalize in the concrete position!
Let's examine your lines:


 1. gh4 cd2 2. ce3 df2 3. ge3 and the follow up moves for black are :
    hg1 4. fe5 gd4 5. ec3 cb4 6. cd4 ba3 7. de5 ab2 8. ed6 ba1 9. fe7 and white will win with 4 pieces against

Start at the end - after fe7 black move fg7, then gh6 then hg5 and draw - you did not count, you generalized.
But step back - why do you save checkers with 7. de5, why not simply kill with fe7 and dc5?

Next example:
 If cb4 4. ac3 hg1 5. cd4 gh2 6. fg5 he5 (if hf4 7. gh6 fc1 or fd2 8. fg7 and white wins with 4 pieces against 2). 7. dc5 eg7 8. cd6 gh6 9. ef4 fg7 10. fe5 he3 11. dc7 ed2 (if eg1 12. cb8 and white move to win with 3 kings) 11. cd8 as white proceed to win with 3 kings by again protecting piece at e5 from being eaten.

Why count all these long endings when 5.ed4, fg7 and cd4 wins instantly?
Be sharp! Look to kill!
