Higgs production in association with a W boson and two energetic tag jets at the LHC is studied for MH = 120 \GeV, with the Higgs decaying to bb and the W to ℓν (ℓ = e, μ), guaranteeing high trigger efficiency. All parton level backgrounds are analyzed, including the effect of fake b--tagging. We discuss two detection strategies: in the first, more traditional, one, two jets are required to be b--tagged while in the second, which has not been previously examined in detail, only one tag is required. After all selection cuts about 80 and 200 events are foreseen in the two cases for a standard luminosity of 100 fb-1 with a S/B ratio of 1/25 and 1/60 respectively. The corresponding statistical significancies, S/√(\mathrm B) are 1.81 and 1.82.
