2C! Yes, you only have 6HCP, but this hand is an exception. If partner has a four card major, you pass. If partner doesn't, you pass 2D. This is quite legal, even though you are lying to your partner. The ideal hand for the "lying stayman" bid is xxxx xxxx xxxxx --. As it is, you run a slight risk of winding up in a 6 card diamond fit, but more realistically, you'll end up in an 8 card major fit or a 7-8 card diamond fit.
