Domino's great in teaching you to put people on a range of possible holdings, and how to "hold them out".
Domino's also great in teaching you to spot tells. This made me very aware as to observe players while playing, while disguising my own tells, helping me net a 5th placing in my first and 'till now only ever live tourney, way back in february.

I want to get in a big buyin live tournament so bad...
