qq facing overshove on flop

Play 1 3 at eastside, have a stack of 800. Probably have lag image although Ive only shown down big hands. Im usually given quite a bit of respect...

I straddle for 6. UTG makes it 18. 1 caller. I wake up with QsQc. I make it 70. UTG calls. UTG has 600ish behind.

FLOP - 964 all diamonds - pot 150

I check, he thinks for a second and shoves...........................................

He starts talking a lot, and even gets money out saying probably gonna rebuy. I tank and fold. He shows KhQd.

What do you do here, What did I do wrong? Ive been massively misplaying big pairs and losing a lot of money with them so my head is all clouded with them... Play here is similar to Gemini, probably more passive and worse

This isn't even close IMO. Very good fold.

His shove to me shows he either has a diamond draw or is protecting from a diamond. He never shows up with a flush or bluff imo. TdTx JdJx AdKx AxQd 99etc. If it were me, id call if i had the Qd in hand, but fold to his ridiculous overshove. Im not much of a math person, but i think if his all in is for 200 or less i make this call.

After seeing his KxQd, youd be calling 600 for 750 and he still has 12 outs plus a backdoor straight draw... PokerStove shows you as only a 56%. This is only a call for an extreme gambler and a rich man imo :) way to avoid the temptation, good fold.
