Threesomes - Getting into bed with kings

[Insty]

I usually don't like having multiple hands in a post but these two were so similar and happened in consecutive games.

Hand one:

SB has been really LAGY, Button has been more sensible but is still seeing about 30% of flops.

Party Poker $10+1 No-Limit Hold'em Tourney, Big Blind is t100 (6 handed)

Hero (t770)
UTG (t925)
MP (t2400)
CO (t2270)
Button (t1000)
SB (t635)

Preflop: Hero is BB with K[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/club.gif[/img].
<font color="#666666">3 folds</font>, Button raises to t225, SB re-raises all-In t545. Hero ?


Hand Two:

Simlar reads Button has been really LAGY, CO less so but by no means tight.

Party Poker $20+2 No-Limit Hold'em Tourney, Big Blind is t50 (8 handed)

BB (t190)
Hero (t835)
UTG+1 (t635)
MP1 (t2065)
MP2 (t1020)
CO (t405)
Button (t1930)
SB (t920)

Preflop: Hero is UTG with K[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/spade.gif[/img].
Hero raises t150, <font color="#666666">3 folds,</font> CO calls t150, Button is all-In t1930 <font color="#666666">2 folds,</font> Hero ?

I know if this is going to be 1 on 1 I really want all my chips in here, and if I find myself up against AA, well, that's just poker.

But what about if I'm going to be 3 way?
Should I like this even more, getting the option to triple up with what is likely to be the best hand hoping to be up against two Ax's or should I be more wary of playing what is essentially a coinflip for all my chips if I'm up against an underpair and Ax?

Thoughts?
