This is my first hand analysis post, please be gentle!!
Tournament is a live casino £30 buy in, with 2 rebuys available (although this hand occurred past the rebuy point, so irrelevant anyway!)
Hero - Has most chips on table due to finding big hands at the right time (AA v KK, KK v JJ). Approx chip count at this point 30k.
Villian - Old Arab man who is moaning about anything and everything. From peoples bet sizes, about the speed of the dealer, about the breaks every 3 levels - you name it! He has approx 25k.
Blinds 800/1600.
Folds round to villan on button who limps. He likes to limp / call a lot!! Hero in SB with

calls, BB checks his option. (4800 in pot)
Flop

, hero checks, BB checks, villan bets 5k. Hero calls, BB folds. (14800 in pot)
Turn

, hero checks, villan jams.
Hero?
