I read this: 2 Times to Play Planning Poker and 1 Time Not To this morning.
The last part in particular is interesting and has taught me something; I’ve sometimes encouraged teams to validate estimates in sprint planning, but Mike’s point seems solid as to why this is a bit pointless; these estimates are supposed to be rough.
