We consider ideal versions of pointwise, discrete and equal convergence of sequences of functions. Defining, in a natural way, ideal pointwise (discrete, equal) Baire classes of functions, we show that these classes are equal to their classical counterparts for ideals for which there is a winning strategy in a game introduced by Laflamme (1996) . In the proofs we make extensive use of a characterization (in terms of filters which are 蠅-diagonalizable by -universal sets) of a winning strategy. This article extends results of Laczkovich and Rec艂aw (2009) , and Debs and Saint Raymond (2009) .
