PREFLOP:
SB: i would assume some standard opening 80-90%
BB: passive defense with something like TT-22, ATs-A2s, KJs-K5s, Q7s+, J7s+, T7s+, 97s+, 86s+, 75s+, 64s+, 54s, 43s, AJo-A2o, K7o+, Q8o+, J9o+, T8o, 98o
FLOP:
SB: most likely sb would bet/3bet any overpair+ or monster draws like As6s, so i consider that he will check/call with any relatively good made hand and relatively good draws. Range estimate is following:
66, 44, A6, K6, Q6, J9, J6, T9-T6, 63s, A8, A7, A5, K8, K7, K5, Q8, Q7, J8, J7, T9, 98, 97, 95, 76, 65, AsKs, AsQs, AsJs, AsTs, KsQs, KsJs, QsJs, KsTs, QsTs, JsTs, As9s, Ks9s, Qs9s, 4s2s, 3s2s, 4s3s, As2s, As3s, Ks2s, Qs2s, Js2s, Ts2s, 9s2s, 4s2s, 3s2s
BB: hero might be check raising with any relatively good draw and top pair+:
TT-44, A9, A8, A6, K9, K8, Q8, J8+, T8+, 98, K6s, 86s+, 76s, 65s, AsTs, As7s, As4s, As3s, As2s, KsJs, KsTs, Ks7s, QsJs, QsTs, Qs9s, Qs7s, JsTs, Js9s, Js7s , Ts7s
TURN:
SB: after check/call i would assume that all 5x and 7x pairs will be folded (in case they do not have some draw), hands that now have 2pair+ i would expect to make a re-raise. Expected range is something like: 66, A6, K6, Q6, J6, T9, T6, A8, K8, Q8, J8, T9, T6, 98, 97, 95, 76, 65, AsKs, AsQs, AsJs, AsTs, KsQs, KsJs, QsJs, KsTs, QsTs, JsTs, As9s, Ks9s, Qs9s, 4s2s, 3s2s, 4s3s, As2s, As3s, Ks2s, Qs2s, Js2s, Ts2s, 9s2s, 4s2s, 3s2s
BB: hero range is pretty much the same as on flop: TT-55, A9, A8, A6, K9, K8, Q8, J8+, T8+, 98, K6s, 86s+, 76s, 65s, AsTs, As7s, As4s, As3s, As2s, KsJs, KsTs, Ks7s, QsJs, QsTs, Qs9s, Qs7s, JsTs, Js9s, Js7s , Ts7s
RIVER:
In general heroes range is still ahead on this river.
The question is what hero expects to get call from? SB range is polarized here and is ether flash or "trash". I don't think it is likely to get a hero call from a pair of 8s. Thus if this is a value bet than hero expects value from flash or possible 2pair that hit river or knowing the above tries to bluff. This makes hero betting range polarized as well.
I would expect check from hero with 2pair, set or straight or hands like 99 on such a river.
SB: as hero's range is polarized in this spot and shifted towards flashes i do not consider this as a good spot for bluff as hero will not fold better hand, thus sb range is mainly flashes.
BB: bet with something like (any flash, 66, 56, A6, 98) and call with flash
