Nagy Game Tries

1Spade - 2Spade - 2NT asks in which suit responder would accept a help suit game try.

Reponses:

after 1Spade - 2Spade

Over 1Heart - 2Heart, same applies, only 2Spade is the ask, with notrump's now meaning spades,

After short suit tries, a repeat of the short suit try is a void suit slam try. A different suit beyond 3M is a cue bid and shows a short suit slam try with a singleton. After 2NT, opener's new suits above 3M show a help-suit slam try (probably in an accepted suit) and are cue bids.
