Philipp Gruissem has continued his dominance at high roller events after winning the £100k WPT Alpha8 London along with £862,400 ($1,379,840). He beat out a 20-player field that featured many of the world's best poker pros.

It's not hard to understand why there were so many elite pros involved since the Alpha8 prize pool was worth $3,145,000. And with just four players cashing, these 20 grinders were all hoping to make it past the bubble. Speaking of the bubble, Tony G was the odd man out when his pocket 7's were no match for Gruissem and his pocket queens.

With play now four-handed, Gruissem (1.15 million chips) now held about 55% of the chips in play. Igor Kurganov (191k chips) was on the opposite end of the spectrum, and he was forced to go all-in rather quickly. His pocket 4's couldn't hold up against Tobias Reinkemeier's A-J combo, and he was eliminated in fourth place (£235,200).

Despite adding to his chip stack, Reinkemeier quickly found himself in trouble. He went all-in with A-3, only be be eliminated when Gruissem's pocket 4's held up. Reinkenmeier finished third and collected £352,800.

This left Scott Seiver (742k chips) to battle against Gruissem (1.26 million chips) for the top prize. Seiver put up a good fight for about an hour, but eventually got all-in with K-Q. He had the misfortune of seeing Gruissem (A-J) win the hand when J-9-4-5-4 was dealt.

With his latest victory, Gruissem adds to his growing number of high roller titles. He's now taken first in the 2011 UKIPT £20k High Roller (£450,200), the 2013 WSOP APAC $50k High Roller (A$825,000) and the Alpha8 London.
