Comparing H and K
Thanks Nack! This was a great exercise.In my OP, I mentioned that I recently studied a group of similar positions where the roll was 32. In those, the hit came with a 2, so there was no example of breaking the 8pt to hit. That meant that I never got a feel for how that factors into the decision. These exercises gave me some experience with that. Now I will go back, and try the 43 roll in my other examples.
Here were my guesses before checking XG. I was only interested in gauging the H/K margin. In some positions, it is possible that neither was the top play.
1a. K by a small amount
1b. H is clear
1c. H by small amount2a. H is clear
2b. H is close
2c. H by small amountHere are the XGR++ evals (if you zoom back, you should see side-by-side board positions):
