25/50 meta game play

[theBruiser500]

5 handed 25/50, real bad player very loose preflop always calls everything gives way too much action post flop on button raises to 175 he has 1200. I just wait for good hands against him, not sure if he's adjusting at all, doesn't look like it but it would really suck if he did. I have 22 and raise to 550 with plan of betting his last 700 on any flop. Flop is Kc Qc Qs and I bet 700 after he calls preflop. I'm in SB.

I did this primiarly for meta game purposes but it seems like an okay play in itself since he'll only flop a pair 1/3 times. Thoughts?
