A bit of background info...

- Solid 1-2 NL player, have no interest in tournies or other games
- Last book i read was the Slansky No limit holdem book that came out last yr (which I read about 10 months ago)
- Just ordered Mathematics of poker frm the stars fpp store.

I'm always looking to improve my game, any other books you reccomend I should get.
