Though this hand could be bid in any system to reach game in ♥s, yet it requires a degree of partnership understanding and bidding style. Undoubtedly hands have a combine game point coverage. Yet the most important things is the shortage in spades opposite only ♠QJxxx (Almost no wastage). In my opinion this hand could easily be bid accurately in any system which either plays Multi 2D with 4441 (17-19 HCP)included or has the ability to show both majors min 5-4 (if 5-4 then ♠are 4 and ♥are 5) or 5-5. Here at our club in Varanasi (India) we play both and can show it either ways. 1. 1♣or 1♦---- 2♥ (shows 5-4 in majors, 7-9 hcps) . ---- 2♠ (shows 5-4 in majors, 10-11 hcps) While playing Multi 2D which includes a)either a weak 6 carder major or b)4441, 17-19 hcps or c)strong acol type hand in any minor the bidding goes; 1. 2♦(alerted) ----- 2♥(forced relay,alertable) 2NT (alerted, 4441) ----- 3♣(relay to show the short suit) 3♥short♠ ----- ? (Simply 4♥ or slam interest) I think this the tricky place where the responder has to calculate precisely whether explore slam or should be content with game only. If the opener has a hand like ♠x ♥KQxx ♦AKxx ♣AKxx the slam is on. With the given hand a lot of guess is to be made and responder should be content with game.
