Close but not clos enough

Yesterday i had 6 horse ACCA , 9/4 winner 6/4 winner 10/1 winner 11/8 winner and 15/8 winner all going on lwillie Mullins Quantum Boy in the 6.0clock bumper and ran as though desperately in need of the run . Mullins usually saves his better bumpers for prestige meetings and I thought he was a good bet .. Also had another five winner ACCA in the week but Fact to file let it down .... Could of easily of won 2.5 k for £7.50 worth of bets
