The Power Of The Four Bet
The average stack is currently a shade over 56 big blinds, plenty of room for four-betting then, as two different players proved.
From under-the-gun Karel Kratochvil opened to 12,000, two seats along Stefan Vagner three-bet to 26,000 and next to act, Andrea Benelli made it 44,000 from the hijack. It passed back to Kratochvil he folded but Vagner made the call. The flop fell 
, Vagner checked, Benelli fired out 55,000 and after a brief think Vagner folded and preserved his 158,000 stack.
A couple of tables over Jorma Nuutinen raised to 12,000 from the cut-off, Emmanuel Francois Murcia three-bet to 29,000 from the button and Lasell King then cold four-bet to 65,000 from the big blind. Nuutinen folded but Murcia stuck around to see a 
flop. A continuation bet of 60,000 from King was enough to win the pot.
