The January 2021 problem, for anyone wishing to advise me
Matchpoints, favorable (opps only vulnerable)
S-AKJ103 H-853 D-void C-AQJ103
Partner opens 2H. RHO passes. Your call?
2NT = Feature ask, 3♥ nonforcing,
4♦ = Splinter, 4NT = RKCB,
5:diamonds: = Exclusion KCB for
Though it doesn’t say, I expect 2S and 3C would be forcing.
Obviously 3H is ridiculous. I’m not going to try RKCB with a void. Exclusion KCB (at 5D) seems like a mistake since we’re often overboard.
At favorable vul, 4H may be enough, but he’s allowed to have a reasonably good weak 2. I’m not sure whether an immediate 5H would be preemptive, but I’m leaning toward starting 2NT, then bidding 4H over 3H or 3D, 5H over 2S or 3C, 6H over 3NT.
