Preflop: Hero is UTG+2 with T[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/spade.gif[/img].
UTG calls, <font color="#666666">1 fold</font>, Hero calls, MP1 calls, MP2 calls, MP3 calls, <font color="#666666">3 folds</font>, BB checks.

Table was loose, so i went for it.

Flop: (6.50 SB) T[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(6 players)</font>
BB checks, UTG checks, <font color="#CC3333">Hero bets</font>, MP1 calls, MP2 folds, MP3 calls, BB folds, UTG calls.

BB and UTG don't seem to be interest, so i bet. Might have the best hand and really don't want to give any free cards if that's the case.

Question number 1:
Would you bet if you were first to act ?

Turn: (5.25 BB) A[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
UTG checks, Hero

Question number 2:
The mother of all cards hits - still keep betting to 3 players ?
