I also played the BUG-Lite. Either A or F=4 due to the 9s in r1 or the 7 in r8c4. Transport 4 from r1c7 to r8c78 via ABCDE; r8c45<>4.

Ted,

There's no 4 in r4c6. May I ask where the elimination occurs and what are the pincers? Just trying to see if I can interpret the notation.

Marty,
DP 45 in R168C456.

BC are <79>.
ABCD is an XY-wing 49-79-47. With transport EF, R4C7 <>4.

Except for a typo, my solution is the same as Ted's. I was simply trying to give Marty a different explanation. A decoder ring for the notation, if you will.

Hi, Dan. I know you're just trying to "wing" it when you throw in an als like this, but an xy-chain is still just an xy-chain.

Oh, and nice BUG-Lite, guys!

I see in light of the comments that I could have transported either pincer and my transport could have been shorter.

The result is the same, but I would never in a million years spot that pattern as an XY-Wing.

(4=9)r1c7-BugLite(45) r168c456[(9)r1c56=(7)r8c4]-(7=4)r7c4-r7c9=r5c9 => -4r4c6


Ted


Ted,

There's no 4 in r4c6. May I ask where the elimination occurs and what are the pincers? Just trying to see if I can interpret the notation.


Marty, sorry about the confusion. My pincers are 4r1c7 and 4r5c9 which deletes the 4 in r4c7, not r4c6. I could claim a typo or insufficient coffee early in the morning but in either case I messed-up.

On the use of ALS in your formulation : (4=9)r1c7-(9=2)als:r2c278-(2=4)r4c2 => -4r4c7 :
...I would argue that there is no ALS...
That is, when =9r1c7 is posited, the once ALS on the board mutates into an LS (here a resolved LS) in the chain.
In other words
(4=9)r1c7-(9=2)LSr2c278-(2=4)r4c2 => -4r4c7
would better reflect the position, though still putting the relevant information (LS) after the deduction (2r2c2) and still leaving the reader to make that deduction.
One way of making things clearer whilst respecting the logical sequence would be for example :
(4=9)r1c7-9r2c7=(56+2)r2c782-(2=4)r4c2 => -4r4c7
where+is a sign of resolution, and the ordering of the LS indicates which is the resolved cell of interest.

How can r2c278 be a locked set when it is three cells with four values (2569)? Pulling the 9 out will make it a locked set but the notation indicates the 9 is there. Confused
