UTG+1 seems to be an average player who has kept his stack at about the same level for 4 hours, not seen any moves made. I have been card dead for about 40 minutes, playing about 2 hands in that time.

Relative stacks:-

Hero £150
UTG+1 £120

Hero is on the button with

4 limpers

Hero raises to £6

UTG+1 calls, MP calls

Flop is (pot £23.50)

UTG+1 bets £15, MP folds, Hero raises to £40, UTG+1 thinks for a while and re-raises all-in.

Hero?
