Logic options open Plans remain fluid for Sagitta 1000 Guineas favourite Queen`s Logic, Mick Channon stressed today. It had been thought that last season`s champion two-year-old filly would warm up for the Newmarket Classic in next month`s Fred Darling Stakes at Newbury. But her trainer said: 'We are keeping our options open - a lot will depend on the ground and on her. 'Like every trainer I am just hoping nothing goes wrong. 'At the moment everything is going right and I am pleased with her - and I think I have got a few nice fillies.' Queen`s Logic has topped the Guineas betting since her runaway win in the Cheveley Park Stakes at Newmarket last autumn, and is currently quoted at 9-4 by William Hill. Stable-companion Golden Silca may be stepped up in trip after her fine effort in the Dubai Duty Free at Nad Al Sheba last Saturday. Channon is eyeing mile-and-a-quarter races for the mare, who finished fourth in the Grade One nine-furlong contest under Richard Quinn. 'She ran a cracker as she must have been 20 lengths behind turning for home,' the trainer said. 'I was pleased with her. 'She is home now and we will have a look at her. The Attheraces Mile is a possibility for her but that may come a bit quick. 'There are a fair few options for her and I think a mile and a quarter may be the way to go with her.'
