Lebensohl is usually not to get you to a marvelous game contract, but to keep you out of trouble. Partner opens 1 NT opps overcall you bid 2 NT (alert) relays partner to 3 clubs (alert) which you will pass of that is your suit or you will bid any non-jump it is to play. If in the event you have the overcalled suit well stopped you will force partner to 3 clubs and then bid 3 NT (alert). if you bid 3 NT directly over the interference (alert) it shows a aise to 3 NT without interfered suit stopped If Partner does not have it stopped he will start runouts at the 4 level with his lowest 4-5 card suit if you have to, you may correct to a suit of your own. Lebensohl is also useful when opps open a weak two bid and partner doubles. A bid by you of 2 NT sends partner 2 3 clubs and you will set the contract. Hope this clears your Lebensohl problems.
