2 hands vs. aggressive player facing a push

[I Am Your Friend]

The villian in this hand is a Party regular, STR8CashHOme, who multitables the 10/20 games. He seems like a pretty solid player, but is very loose and aggressive. He seems to like to make random raises for any amount with any two cards and uses his position well.

He's multitabling right now, but is stuck a lot between his four tables and seems to be tilting on them, except for this particular table where he is up and seems to be playing normally.

Hand 1

My stack is $3000. His stack is $5000.

One early position limper to me and I raise in late position with K [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/spade.gif[/img] to $80. The SB folds. He calls in the BB. Limper calls too.

The flop is Q [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/club.gif[/img]

He bets $185. The limper folds and I just call.

The turn is 4 [img]/images/graemlins/heart.gif[/img]

He checks. [img]/images/graemlins/mad.gif[/img] I bet $450. He seems to hesitate for a while and then calls.

The river is the 5 [img]/images/graemlins/diamond.gif[/img] and he pushes all in. What should I do here? [img]/images/graemlins/crazy.gif[/img]

HAND 2

This is a while later on a different table. He's calmed down some of his LAG play.

My stack is $2600. His stack is $2000 (He just reloaded after getting rivered in a big pot)

He open limps in MP. Three limpers follow him. I raise in the SB with Q [img]/images/graemlins/heart.gif[/img]Q[img]/images/graemlins/spade.gif[/img] to $160. Only he calls.

The flop is 9 [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/club.gif[/img]

I bet $250. He pushes. What do I do now? [img]/images/graemlins/crazy.gif[/img]
