after 1d (1s), can X be made on any number of hearts or should it be 4 exactly. pretty sure can X with quite a few hearts and then sign off in 2h on next round of bidding. correct me if wrong also for 1s (2d), what about X here? is it always 4.

also if doubling, what are your bids after various possible bids by pt.
