AJ clubs in SB did I wimp out?

[FA_man]

Hi everyone, ive been reading the forumns a while and this is my first post.

3/6 game online

Ive been dealt AcJc in the SB

UTG and solid player limp. I raise the SB thinking Im likely to be ahead of hands that are easier to call in CO. BB, UTG, CO call. Flop:

10s5h6h

No flush for me. I check my overcards. CO bets. I decided to checkraise to try and get a better read, and maybe knock out a flush draw. BB and UTG fold CO reraises.

I had decided ahead of time that if i was reraised I would fold. And one thing I find myself doing is justifying staying in too long even after decisions like this. This time I bit down hard and mucked. Did I wimp out?

What do you guys think?
