Hi, I often use the Losing Trick Count (LTC) to double check a proposed bid when in doubt. I make adjustments for Aces, Queens, and extra trumps - and try not to get too religious about it. I've seen people mention cover cards in relation to the LTC, and I've no idea what this is nor how to use it :) I'd be grateful if someone would explain this for me - or point me to a reference. Thanks, Nick
