If there were a kind soul who could point out to me what I am missing in this one: at such a late stage it ought to be obvious but I am darned if I can see it:

*25 1*4 37*
*47 *23 18*
13* *7* *2*
*9* 261 547
754 938 261
216 457 893
*7* *** *12
*82 71* 63*
*61 3*2 758

Thank you in advance!

An X-Wing .

An X-Wing

I was afraid of this! One of my pencilled possibles must be wrong.

According to my pencilled possibles, in every pairing of either 2 rows or two columns, one of the defining rows(columns) has 3 instances except for the only X-Wing which I can see in the number 3 [ r4c1 & r4c3 with r6c1 & r6c3]. Which doesn't actually help.

So could you put me out of my misery? Where the *!£$* did I make the mistake?

First you've made a mistake it's [r7c1 & r7c3] and yes the threes don't help.

For an x-wing look at the 9's in c3 and c7.
Then look at c6.

Thanks very much, MCC! Someone has to write a thesis on 'acquired blindness' --- I must have been over those 9's 50 times and still succeeded in missing the X-wing!
