- don't think should force to 4 level with 10 HCP opposite a balancing double, 3s should be a stronger hand. I think bidding 3H is enough.
- why should 4c show 4+d, 4+h, twice rebiddable clubs? It was forced by partner's cue, should still be 3+,3+, 4+ on suit lengths, and probably no spade stopper
- seems like somebody should be bidding hearts at some point, not that it really fares much better with the 5-0 break here, but getting to a heart contract will score better most days.
