The trainer, who had earlier seen his filly Maoineach beaten, said: "I came here expecting to win two races but this game would tame lions.
"I would say Vocalised would be better on better ground, and he will now probably go to Paris.
"He isn't entered at Newmarket, and I thought at that stage I had enough horses for that race.
"I would be surprised if he gets the Derby trip, but he is hardy.
"Intense Focus will to Newmarket, and I'll have to see if Gan Amhras will run as well. He was going to run tomorrow at Leopardstown but he can't go there as the ground is soft.
"For him it will be either Newmarket or York for the Dante - and the ground will be the deciding factor there.
"Intense Focus is in good shape and both he and Vocalised would be entitled to run in any Classic over a mile.
"Gan Amhras will be better suited by 10 furlongs to a mile and a half."
Dewhurst winner Intense Focus had the likes of silky-smooth Craven Stakes winner Delegator and Aidan O'Brien's Rip Vaninkle behind when scoring at Headquarters last autumn.
Bolger added: "It was a last-minute decision to run Intense Focus at Leopardstown as we were expecting soft ground and it came up better than that.
"We ran him but he needed it and it probably came a week too early.
"The Dewhurst is always a good race and Delegator looks to be the one, but Aidan (O'Brien) is very happy with Rip Van Winkle."
