PRO:Karl Mahrenholz GAME:Newcastle GUKPT 300GBP NL Holdem BLINDS: 100/200
CHIPS:18,000
THE SITUATION: A new player to the table limps for 200 from mid position. It may be the first hand he's played but I,ve already tagged him as quite weak based on his body language. I make it 800 to go next to act with 6

6

. Martin Silke (winner of the GUKPT London main event) calls the 800 from a stack of around 8k or 9k. To his left is quite a bad active player who folds. As he folds, Martin says in my direction 'Oh, I thought he was going to raise.' The limper calls, also playing around an 8-10k stack. The flop is 7

5

. The limper checks and I check to Martin, who I know can be reasonably aggressive. Martin quickly bets 2,100, just under full pot, leaving himself about 6k. The limper then goes into the tank,counts out a call, counts out how much he is left with, and finally calls the 2,100. What is my best move here?
