hands to consider - 1 of 2

[marbles]

These two hands are from an online freezeout tournament, but they're from very early on, when the table was playing like a basic low limit table.

Hand 1 (from second orbit, very little read on anyone):

I get dealt KK (suits unimportant) and openraise in MP. Button coldcalls, BB calls.

Flop is 884 rainbow. Checked to me, I bet, button drops, BB calls.

Turn is an ace, completing the rainbow (A884). Checked to me, I bet, BB checkraises, I fold.

What do you think?
