Player cost himself 1000 points in poker

[Housemoney]

There were 4 cards to the Royal on the table. He had the 10 of spades in his hand. He went all in after he hit it on the river causing myself and Yisman to fold. If he checked it down, he would have pocketed 1000 points.

Hope he finishes first place and wins the 500 or so.
