Mohan Weak NT Defense

The basic idea is to use transfers in order to give the overcaller a chance to bid twice with very good hands. Initial actions are:

Dbl= Good 14+, usually balanced
2C = Both majors
2D = Transfer to hearts
2H = Transfer to spades
2S = Spades and a minor
2NT= Hearts and a minor
3C = Natural
3D = Natural
3H = Natural, preemptive
3S = Natural, preemptive

Note that initial actions are sound overcalls.

Advancer's Actions
After a double following weak notrump bid, some play system on, some play natural. Jump bids show game interest.
