[King High]

20/40 Foxwoods. Not an overly tight game 1 or 2 weaker players a few rocks. Most pre flop raises being called by anyone all ready in.

I am on the button with Ad 10d it is raise in mp by a firly tight player called by lp myself and the bb.
Flop 7 8 10
bb bets out raiser raises lp folds I three bet is this logical. My thinking was fold or raise?

Hand 2
Lp I limp in behind 5 others with Q9s
Flop K 9 3 rainbow. It is checked around.
Turn Q
It again is checked to me I bet UTG raises all fold to me I reraise.
River blank
I bet out. I didn't put him on j 10 but a weak k. Comments Please

Thanks
