Hello Hold'em players! 2 Hold'em questions...

[SittingBull]

U have 78(suited)
U KNOW your single opponent has K9o .
The flop is 7 K 2 (R) U have no backdoor draw. [img]/forums/images/icons/laugh.gif[/img]
If your opponent bets 1/2 BB on the flop and the pot size is 5BB,would U call his bet??

If the turn board is 7 K 2 3 and U have no flush draw,would U continue to fish if the pot were large enough if U did not improve on the turn?? If so ,how large(in turns of BB's) must the pot be for U to call 1 BB?? Give min pot size in BB units.
Thanks
Sitting Bull
