sounds like he could have lots of hands here : from the dreaded aj,kj,qj,jj,jt,j9,j8 ~ 80 hands+ some jx ~20= ~100
to he ones you beat: ak,aq,at,a9,a8,aa,kk,kq,kt,k9,k8,tt,88,some lower pairs and lots of flush semi bluffs more - at least 120 hands, probably 150+.
raising seems like having value here (not sure i would've done it in battle though, too weak probably). folding not an option right? (10 outs if behind), calling gives him a cheap shot if he has a flush draw.
