Freddie Robdal stayed on well to win the concluding Lismore Handicap Chase in Tramore as the fog reduced visibility. Know The Game led over two out with Freddie Robdal soon improving to challenge him.
They both jumped the last nicely and Know The Game was ridden on the short run-in by Keith Donoghue to win his race, however, Rachael Blackmore drove Freddie Robdal upsides in the final 50 yards and her mount got up by a nose close home on handicap debut.
The six-year-old gelding came in at 15/2 and gave Blackmore a double on the card as she was earlier successful aboard Saint Sam in the Tramore Racecourse Directors Chase.
Runner-up Know The Game was priced at 13/2 and he was six lengths clear of gambled-on Malinas Glory (10/1 - 13/2).
Henry de Bromhead said: "He is owned by friends of Dave Clerkin who passed away in 2018. They've just told me that Dave would have been 35 today. It's a special day for all of them, it's brilliant.
"I told them that the ground was too soft, he had no chance and that we'd get him a bit of experience and there you go, it shows how much I know! We've had tough days with this horse but Paul (Boyle) has kept the syndicate together and it's brilliant."
