Q2 with marginal river decision

[Sir Winalot]

I have a note on SB which says he might be a slowplayer, otherwise he seems to be decent from what I've noticed.

50NL
SB ($39) villain
Hero ($65)
UTG ($53)
MP ($38)
CO ($45)
Button ($36)

Preflop: Hero is BB with Q[img]/images/graemlins/diamond.gif[/img] 2[img]/images/graemlins/heart.gif[/img]
fold, MP calls, fold, fold, SB calls, Hero checks

Flop: T[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/spade.gif[/img] ($1.5)
check check check

Turn: 8[img]/images/graemlins/heart.gif[/img]
SB bets $1, Hero calls, MP folds

I think this is all quite standard this far.

River: K[img]/images/graemlins/diamond.gif[/img] ($3.5)
SB bets $2.5 <font color="red"> Hero? </font>
