regarding 罗明士杯个人赛 and 团体赛, the formal MP 罗明士先生, many years with 甘榜格南, stepped down after the Singapore General Elections held in May 2006, the 个人赛 was renamed as 甘榜格南象棋个人赛 and still continue until now, as for 团体赛, from what I heard also due to a complaint during 2005 罗明士杯团体赛 and ended up with the present situation.
As mentioned in some of the earlier posts, the organisers are volunteers, usually they do not mind to spend times to plan and arrange the competitions, but they do have a strong feelings if there are complaints after the hard works.
