Cure for a shank?

I play off 22 and am driving better than ever.

However I am shanking my irons.

The more I try the worse it becomes.

Anyone got any good tips?

Ok !.Get your golf umberella (closed of course.) lay it on the ground, about 3 inches on the other side of your ball. pointing along the line you want to hit. Then just hit the ball. your subconcious will stop you hitting the umberella and keep your club swing on the right plane. then just 100 balls and you will be cured.... if it works just send me £10 pounds in an envelope. this also applies to anyone else who reads this post. cheers !
