Study the contrast in these moves (unlimited):

64S, 63S & 62S (21)

64S, 63S & 62S (41)

64S, 63S & 62S (31)

Make sure you are comparing across second rolls as well as first rolls. Where 31P is best, look at H and X anyway. Consider why P is best and why X or H is best.

Now note that H improves vs X at DMP for all variations. You probably noted this already. Don't worry about which move finishes best. Just learn why H improves vs X. Or you can go in the other direction: learn why X improves vs H at unlimited.

Your goal is to understand the features of the position (including score) which favor H and those which favor X. If you succeed, you will be ready to apply this knowledge to positions later in the game.
