Live 5-10

[ho chee mihn]

I've been playing in a local live 5-10NL game that runs twice a week, the max buy in 2000

Anyways a large 3-way hand devloped and i'm curious as to what to some NL cash players think about sb's play (he says it the right call but i don't know. my play is obv auto-pilot and i'm not concerned about my play but rather sb's call and whether it is a good/bad call.

sb: very lag, likes to c/r lots of draws, tricky for this game's standards
bb: calls down lots of hands, loose/standard, old rich dude, plays solid

me: (3075)
SB: (3k+)
BB: (1375)

me: (QdQs)
SB: _ _
BB: _ _

folded to me who bets 50
SB: calls
BB: calls

FLOP: Qh5h6c
SB: bets 75
BB: calls 75
me: raises to 300
SB: raises to 800
BB: Raises all-in to 1200
me: Raises to 2650
SB: calls 1850

main pot: 4125
side pot: 3400

Turn: 9h

River: Jh

showdown:
SB shows (4h2h)
BB shows (Ah6h)

BB wins main pot
SB wins side pot

Obviously SB should fold preflop. I don't like SB's 3bet to 800, as he's at best a coinflip and the bet has little FE. Once he's put that 800 in there, however, he's committed and has to call the push.
