So a situation happened to me during the Giant at the WSOP and I am wondering how I should have proceeded.

I have K/3 in the BB and I defend to a raiser and a caller. The flop is k/10/3 so I have two pair. The 1st guy bets 1,000 (this is in one of the 1st levels) and the 2nd guy calls the 1,000. I think a moment and decide to raise to 5,000 and throw out a single 5,000 chip without saying anything. I don't realize immediately what this means and look at my opponents then realize when the dealer says that I have a few 1,000 chips so just throw a 1,000 chip in. So I unintentionally made the call with the oversize chip rule. I didn't say anything and acted like it was a simple mistake of grabbing the wrong chip by putting in a 1,000 and tried not to betray that I meant to raise.

What should I have done though? What would have happened if I had said "I meant that as a raise"? I feel like that would have just messed up my strategy for the hand and potentially screwed it up or I even could have been accused of an angle shoot.

The turn ended up being another K and the river a 10 and the 1st opponent had k/10, so I ended up getting lucky with a chop and it was really no issue in the end and I never said afterwards that I had meant to raise.

There shouldn't be anything that you could say to change it to a raise. You should simply accept that you made en error, and played on like you did.

Well, no matter what you intended, you know that the oversize chip was just a call, so sure, play along with it however you want. Saying you meant it as a raise is just going to delay the hand going forward in exactly the same way, only now your opponents have extra knowledge about your hand. You'd essentially be angling yourself.

It still would have been a call. You should get in the habit of verbalizing your bets rather than throwing chips around willy nilly.

Not saying anything is correct, no point in protesting now.

Also fold pre.

You meant to raise, but you didn't raise.

Good thing it wasn't a raise for you. K-10 may have come back over the top to get either you or the other caller out, especially if there was a flush draw out there. You might fold thinking he has a set of 10s and not even get your chop.

Did you really not realize that your action was a call? Or did you have a momentary brain-fart?
