Just going to keep it general, playing a .05/.10NL table, I raise first to .40 first with two callers, the pot is 1.20. The flop is 4-7-J of diamonds and I have first shot. I had K-K so I raised to $1; one folded and one called. Next card was a2 of hearts, I checked and got an all-in rasie of around $5. I folded.

In that situation, should I have just checked post-flop?
