The Weekly Extreme Str8ts Puzzle

by Andrew Stuart

WARNING: This is the Weekly 'Extreme' Str8ts.
Only attempt this puzzle if you have time and patience.
Using the solver will not help you. (much).

Oct 18th 2024
The solver can now handle Str8ts variants. Yay! The solver button on the player will now pass an appropriate parameter.

 Klaus, you confuse me. After the solver stops and some obvious eliminations in columns 6 and 3 are made, my next step is the elimination caused by the obvious setti...what is yours...?

 (almost) SPOILER ALERT

@Jan - check the upper right quadrant carefully. The same thing happens again later.

 Used 3 quite simple non-solver-steps: Gap in row B, naked quadruple in col 3, hi/low in col 6. No wing, no UR, no setti needed.

 I can see a gap in B3, which clears some cells in row J.

 In addition I found an Xwing in cols 45. So no BCA is needed.

My definition of "Basic" is when an elimination can be made purely by looking at the contents of a single compartment. In this case, some deductions required consideration of multiple compartments in the same row/column. So, logic that many grade as CE or VCE.
