Pidgin: contract bridge bots from self-play
Weights for the bots in https://github.com/hsperr/pidgin. Code, training recipes and the server live there; this repo only holds the weights.

| PidginV1 | D_cw_s75k.pt |
play_E48_wideleagueH.pt |
| BRL | brl_fsp_weights.npz |

play_B2g_s540k.pt |

Other files: belief_r2.pt (belief net for the bidding search),
bench_100k.npz (frozen card-play benchmark), and play_E48_leagueE.pt
(the compact self-play card-play model). Filenames retain their original identifiers;
use the team names above when choosing a bot.
brl_fsp_weights.npz is not ours: it is the FSP bidder of Kita et al. (2024),
