I open 1D, partner bids 1nt. I bypass the brain and bid 3nt.

Some say the better bid is 3C, strong jump game forcing showing 5D,4C
Partner does not have a 4 card major. We have a minor game, slam perhaps.

Im still reading sbout the case for bidding 2S (reverse), will post my thoughts later.

Regardles, this was with a new partner, we had not discussed reverses, strong jumps etc - my lesson is THINK and trust your partner. :-)
