Flop check

[Rico Suave]

I wanted to get your opinions on this flop check.

Pretty meh online game.

Don't know much about MP1. He seems aggressive enough, seemed normal for typical online 3/6 guy--though I don't know what to make of the open limp.

MP2 likes to overlimp alot. He peels flops quite a bit, plays the turn more aggressively than flops, and goes to showdown a lot.

MP2 knows I am pretty aggressive preflop, postflop, but I don't showdown tons, and probably fold too much postflop.

3/6 Hold'em (10 handed)

Preflop: Hero is MP3 with K[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/heart.gif[/img].

MP1 checks, MP2 checks, Hero checks.

I bet here 99.9% of the time, for all the obvious reasons (best hand, no free cards, position, yada yada yada). I am pretty sure that the responses will mostly reflect that sentiment.

However, is there any argument for checking in this situation? I am getting called on that flop a ton, and getting c/r a decent amount. Checking does not mean giving up, as I can still call/raise/bet the turn depend on turn card and action. I also know my check will look out of place, as any hand is betting there nearly 100% of the time.

So, any takers?
