Villain is super passive so
far-kinda weak imo.  I'm playing aggressive and not getting played back at
a ton so far(i.e. 3bet/4bet).  I have 16.6K a few hands after losing
half my stack when AQ > than my AK aipf(really only time I think i've been played back at on this tabe).  Villain has 13.5K and BB has
42k.

preflop: At 250/500/40; folds around to me in MP, I open with 89s to
1k, CO calls 1k, BB calls 1k(main=3570)
Flop: Ah10s7d; I bet 1785, CO raises to 4070, BB folds, so I??????

Anyone opposed to jamming here to get him to fold any non-two
pair/non-AK hands? obv. he is snapping a set, 2p, or AK here.  Do we
still hate a high variance ship here, or is best line to fold to this
guy who been playing fishy like nemo and all of a sudden raises on
board where he is usually reppin' A10, A7, 1010, 77, 710s, etc.

Any input appreciated-thanks!
