01: 3H (we haven't really convered this, but with a 6-card major and potential game, invite at 3)
02: 2S (transfer to C, then pass)
03: pass (have 5 card suit, but balanced)
04: 4H (looks perfect!)
05: pass (the ugly 4-4-4-1 distribution and too weak for game)
06: pass
07: 2H (transfer to 2S, then bid 3D, asking opener to choose between the 2 or bid NT, then bid game or even investigate slam)
08: 2H (transfer to 2S, then bid 3H (naturally), asking opener to choose, then bid game)
09: 2C (stayman; if opener bids 2S, then go to 4S, otherwise to 3NT)
10: pass
11: 3NT
12: 2H (transfer to 2S, then bid 3H (naturally); should end up in 4H, 4S or 3NT)
13: 4H (why not? unless you're worried about missing out on a potential slam, hmm ...)
14: 2H (again, transfer to 2S, then bid 3H (naturally); probably good enough to risk game)
15: 2D (transfer to 2H, then probably pass)
16: 2D (transfer to 2H, then 3NT (or maybe 3C)
17: pass
18: pass (could risk 2C (stayman), but if opener bids 2D, then you may end up in a tough game)
19: 2C (hmm ... stayman will work nicely, IF opener has a major; otherwise, will have to improvise (maybe 3D over 2D?) or risk 3NT)
20: 2D (transfer to 2H)
