Twice a week.

Yeah, it's called the professional was drunk.

Pretty much, that is just a fantasy.

Could you step into the ring with a pro boxer and upset him with crazy moves? Without being very sound the way he is?

Ok, then. Now we have the term. Salam

If there is a term, it's surely another one of those German terms like "zugzwang," something like "derkinderblitzdermastermitdermadmove."

My apologies to all German speakers!

In South Africa it's known as the zilqida exceeder.

I think the word you're looking for is flagged. That's the only way that could happen.

The closest thing to doing this is called a swindle.

More commonly a player in a stronger position is sometimes swindled into a stalemate and then he doesn't get the win.😽

.. Not, spot on, as to how you described it ; But pretty close ; And a borrowed {former 'Federal Reserve' chairman}, "Alan Greenspan" descriptive quote, at that !

'IRRATIONAL, EXHUBERANCE'

Yes, the term is impossible.  Especially when the novice cannot spell professional.  

Thank you all for the feedback and the learning experience
