OK, makes sense now. Glad this isn't Omaha.
However, from my standpoint (playing NLHE), when I'm talking about a pot sized bet, I'm calculating my odds (what I'm paying to play vs possible rewards). In this instance (assuming just a call), I'm risking $8 more dollars to win a possible $29 that's already in play (or 3.5 to 1). Obviously a raise was the right play here.
A pot sized raise in my mind is putting as much out there as there already is on the table. This is purely for bet sizing, and not the technical Omaha "pot". I've heard some say I could have done a tad more, say $35-45, so I might have bet a bit too low? Glad it worked out. I wonder if I'd bet $45, if MP would've gone all-in (I'm guessing no). And would that have caused CO to change his action? OK, that might be overanalyzing things a bit.
Otherwise, this has been interesting, and I've definitely learned a few things in this thread.
