Add tools for practicing play (even if not full play of the hand)

It'd be nice to have a place to practice suit combinations--basically learning to apply http://www.bridgehands.com/S/Suit_Combination_6.htm

I know saycbridge is centered on bidding practice, but was just wondering if you've considered play of the hand practice?

We've experimented with building a play engine (hard), but never with practicing play best-practices. I think building some play practice help could be interesting. We'd want to make sure to re-do whatever statistics underlying those play rules to validate that they're sound. :)
