Q's simulation slightly prefers NUN. JS tells me that he prefers that board shape against a lower seed, but I also feel like I don't want a bunch of one-pointers that don't really bingo that often. Sim has nun up by less than a point #strategysmall I suppose?
H12 HONE +42 Strategy Small
Duplicates make me blind. Hold INN and score 6 more with HOPE! #strategysad

LIMINAL is so clearly the play #knowledgesaddest
N2 PECTiN(E)S +72 Knowledge Small
Can't make myself pull the trigger on PoTENCES for 4 more. No 9s available but I spent way too much time looking and trying to talk myself out of SERPENTIC* #knowledgesad

K10 VIBES is best #strategymedium

This seems totally wrong when there are plays that bingo a huge amount. For example, if I am going for the A (the main goal of this play), I can play 15K IT, which bingos with every single combo with the A besides AR and AA, but it can be blocked by OLDER 11H or (H)OLDER M3, OARED 11H. Quackle suggests CR(U) J12 wihch also bings a lot, but Jeff can play stuff like AE/ECRU to block, so that doesn't seem like it. Maybe 6I (E)R. I saw I was drawing TRAN(Q) so often here especially with an inference, and I was going down by only 17. I figured I was winning so often whenever I drew a vowel, but I don't think that's necessarily true. TRAN(Q) would take Jeff by surprise, but only puts me ahead 42 not including his play. If he plays 4 tiles such as with DALE A1, he's threatening to go out and win anyway. I can do better with IT, certainly. #strategylarge

4J HA(A)R seems best, leaves S hooks on the board and balances #findingmedium
