I think it's my first hand at the table, no reads.

Preflop: Hero is BB with 8[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/heart.gif[/img].
UTG calls, MP calls, <font color="#CC3333">CO raises</font>, <font color="#666666">1 fold</font>, SB calls, Hero calls, UTG calls, MP calls.

Flop: (10 SB) T[img]/images/graemlins/spade.gif[/img], 2[img]/images/graemlins/diamond.gif[/img], 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, Hero checks, UTG checks, MP checks, <font color="#CC3333">CO bets</font>, SB folds, Hero calls, UTG calls, MP calls.

5 way pot, top pair medium kicker out of position. Is there a consensus for check-raising or donking? Are both of these better than check-calling?

Turn: (7 BB) A[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
Hero checks, UTG checks, MP checks, CO checks.

Planned to check-fold this.

River: (7 BB) 3[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
Hero checks, UTG checks, MP checks, CO checks.

With the A checked around, is this a value bet? Or is it safer to check-call because original raiser could have played JJ-KK very passively on the turn, not to mention who knows what the other players have.

Final Pot: 7 BB
