turn donk bets always confuse me.. check this one out

[yourface]

Second hand at this table, no reads.

Party Poker 0.50/1 Hold'em (10 handed) FTR converter on zerodivide.cx

Preflop: Hero is MP3 with 5[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/spade.gif[/img].
<font color="#666666">2 folds</font>, UTG+2 calls, <font color="#666666">2 folds</font>, Hero calls, <font color="#666666">2 folds</font>, SB completes, BB checks.

Not enough callers to play profitably for set value? Usually I can count on the blinds coming along for one

Flop: (4 SB) 8[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/spade.gif[/img], 4[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, BB checks, UTG+2 checks, <font color="#CC3333">Hero bets</font>, SB folds, BB folds, UTG+2 calls.

Turn: (3 BB) K[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">UTG+2 bets</font>, Hero ?

I hate this situation..

Advice on all streets would be appreciated.
