I will definitely be giving the shades a go. My experience at luton told me I should change my name to "Janet and John". If I raised with strength, I only took the blinds. When I was "at it", I was reraised just about every time. On reflection it may have been my hands (as in "on the end of wrists") that gave me away, So I may have the following routine now
1. look at cards
2. Put on sunnies
3. Put on wooly mitts
4. announce raise
5. er...... get dealer to put my chips in for me?
