It seems to me that when someone overbets the pot by this much, he wants to take it down right now to avoid getting outdrawn. I would say he has something like
[Td] and doesnt want a
to fall on the turn.
I could call but if a club falls, what do I do? If Im right about his hand you would think he wouldnt put any more money in the pot, but since his ridiculous bet tells me hes a donk, who knows what he will do even without a club. What if I check to him and he all of the sudden decides that the 4th club scares me and he bets anyway?
I guess what Im saying is that this bet is weird enough that its pretty obvious he doesnt know what hes doing so I cant play it like a normal hand.
Hes obviously pretty proud of his hand right now, so why not check raise all in before he chickens out?
