01: 2H (preemptive)
02: 1C (not quite strong enough for (artificial) 2C)
03: 1NT
04: pass
05: 1D
06: pass
07: pass
08: pass
09: 1D (with 2 4-card suits, we bid the lower-ranking first)
10: pass (technically you have 12 HCP, but the QJ is very vulnerable, so I'd give this 10 or 11)
11: 1NT
12: pass
13: pass
14: 1D (with 3 4-card suits in C/D/S, bid 1D)
15: 1S (too strong for 2S, and should give a couple of distribution points)
16: pass
17: pass
18: pass
19: 1NT
20: pass
